Prefer HTTPS to FTP and HTTP in documentation Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.

(cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements.

Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted.

(cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks.

Backslash cleanup in Elisp source files This patch should not change behavior. It typically omits backslashes where they are redundant (e.g., in the string literal "^\$"). In a few places, insert backslashes where they make regular expressions clearer: e.g., replace "^\*" (equivalent to "^*") with "^\\*", which has the same effect as a regular expression. Also, use ‘\ %’ instead of ‘\%’ when avoiding confusion with SCCS IDs, and similarly use ‘\ $’ instead of ‘\$’ when avoiding confusion with RCS IDs, as that makes it clearer that the backslash is intended.

Backslash cleanup in Elisp source files This patch should not change behavior. It typically omits backslashes where they are redundant (e.g., in the string literal "^\$"). In a few places, insert backslashes where they make regular expressions clearer: e.g., replace "^\*" (equivalent to "^*") with "^\\*", which has the same effect as a regular expression. Also, use ‘\ %’ instead of ‘\%’ when avoiding confusion with SCCS IDs, and similarly use ‘\ $’ instead of ‘\$’ when avoiding confusion with RCS IDs, as that makes it clearer that the backslash is intended.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def.

(cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?).

(cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable.

Merge from upstream, upto version 5.22. After 5.0: `cperl-add-tags-recurse-noxs-fullpath': new function (for -batch mode) After 5.1: ;; Major edit. Summary of most visible changes: ;; a) Multiple <<HERE per line allowed. ;; b) Handles multiline subroutine declaration headers (with comments). ;; (The exception is `cperl-etags' - but it is not used in the rest ;; of the mode.) ;; c) Fontifies multiline my/our declarations (even with comments, ;; and with legacy `font-lock'). ;; d) Major speedup of syntaxification, both immediate and postponed ;; (3.5x to 15x [for different CPUs and versions of Emacs] on the ;; huge real-life document I tested). ;; e) New bindings, edits to imenu. ;; f) "_" is made into word-char during fontification/syntaxification; ;; some attempts to recognize non-word "_" during other operations too. ;; g) Detect bug in Emacs with `looking-at' inside `narrow' and bulk out. ;; h) autoload some more perldoc-related stuff ;; i) Some new convenience features: ISpell POD/HEREDOCs, narrow-to-HEREDOC ;; j) Attempt to incorporate XEmacs edits which reached me Fine-grained changelog: `cperl-hook-after-change': New configuration variable `cperl-vc-sccs-header': Likewise. `cperl-vc-sccs-header': Likewise. `cperl-vc-header-alist': Default via two preceding variables `cperl-invalid-face': Remove double quoting under XEmacs (still needed under 21.2) `cperl-tips': Update URLs for resources `cperl-problems': Likewise. `cperl-praise': Mention new features New C-c key bindings: for `cperl-find-bad-style', `cperl-pod-spell', `cperl-here-doc-spell', `cperl-narrow-to-here-doc', `cperl-perdoc', `cperl-perldoc-at-point' CPerl Mode menu changes: "Fix style by spaces", "Imenu on Perl Info" moved, new submenu of Tools with Ispell entries and narrowing. `cperl-after-sub-regexp': New defsubst `cperl-imenu--function-name-regexp-perl': Use `cperl-after-sub-regexp', Allows heads up to head4 Allow "package;" `defun-prompt-regexp': Use `cperl-after-sub-regexp', `paren-backwards-message': ???

"Face for highlighting trailing whitespace."
(top-level): Clean up `eval-when-compile's and assorted defvars. (cperl-invalid-face): Don't double-quote value. Change custom type. (cperl-mode): Set normal-auto-fill-function and don't zap auto-fill-function. (cperl-imenu--function-name-regexp-perl): Renamed from imenu-example--function-name-regexp-perl. (cperl-imenu--create-perl-index): Renamed from imenu-example--create-perl-index. (cperl-xsub-scan): Don't require cl.

:version "21.1"
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

:type 'boolean
(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28.

(cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1.

Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>.

Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too.

Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine.

(cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state.

(cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'.

Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28.

Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd.

(cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?).

(cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro.

(cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx.

Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early.

(cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?).

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx.

Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro.

Prefer HTTPS to FTP and HTTP in documentation Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.

want it to: put the following into your .emacs file:
Fix some more docstring etc. quoting problems Mostly these fixes prevent the transliteration of apostrophes that should stay apostrophes. Also, prefer curved quotes in Bahá’í proper names, as that’s the preferred Bahá’í style and these names are chock-full of non-ASCII characters anyway. * lisp/emacs-lisp/eieio-core.el (eieio-defclass-autoload) (eieio-defclass-internal): * lisp/emacs-lisp/eieio.el (defclass): * lisp/hi-lock.el (hi-lock-mode): Don’t transliterate Lisp apostrophes when generating a doc string or diagnostic. * lisp/international/mule-diag.el (list-coding-systems-1): * lisp/international/ogonek.el (ogonek-jak, ogonek-how): * lisp/mail/sendmail.el (sendmail-query-user-about-smtp): * lisp/vc/ediff-mult.el (ediff-redraw-registry-buffer): * lisp/vc/ediff-ptch.el (ediff-fixup-patch-map): Substitute quotes before putting them in the help buffer.

Merge from upstream, upto version 5.22. After 5.0: `cperl-add-tags-recurse-noxs-fullpath': new function (for -batch mode) After 5.1: ;; Major edit. Summary of most visible changes: ;; a) Multiple <<HERE per line allowed. ;; b) Handles multiline subroutine declaration headers (with comments). ;; (The exception is `cperl-etags' - but it is not used in the rest ;; of the mode.) ;; c) Fontifies multiline my/our declarations (even with comments, ;; and with legacy `font-lock'). ;; d) Major speedup of syntaxification, both immediate and postponed ;; (3.5x to 15x [for different CPUs and versions of Emacs] on the ;; huge real-life document I tested). ;; e) New bindings, edits to imenu. ;; f) "_" is made into word-char during fontification/syntaxification; ;; some attempts to recognize non-word "_" during other operations too. ;; g) Detect bug in Emacs with `looking-at' inside `narrow' and bulk out. ;; h) autoload some more perldoc-related stuff ;; i) Some new convenience features: ISpell POD/HEREDOCs, narrow-to-HEREDOC ;; j) Attempt to incorporate XEmacs edits which reached me Fine-grained changelog: `cperl-hook-after-change': New configuration variable `cperl-vc-sccs-header': Likewise. `cperl-vc-sccs-header': Likewise. `cperl-vc-header-alist': Default via two preceding variables `cperl-invalid-face': Remove double quoting under XEmacs (still needed under 21.2) `cperl-tips': Update URLs for resources `cperl-problems': Likewise. `cperl-praise': Mention new features New C-c key bindings: for `cperl-find-bad-style', `cperl-pod-spell', `cperl-here-doc-spell', `cperl-narrow-to-here-doc', `cperl-perdoc', `cperl-perldoc-at-point' CPerl Mode menu changes: "Fix style by spaces", "Imenu on Perl Info" moved, new submenu of Tools with Ispell entries and narrowing. `cperl-after-sub-regexp': New defsubst `cperl-imenu--function-name-regexp-perl': Use `cperl-after-sub-regexp', Allows heads up to head4 Allow "package;" `defun-prompt-regexp': Use `cperl-after-sub-regexp', `paren-backwards-message': ???

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine.

Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early.

Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'.

Note that even with newer Emacsen in some very rare cases the details
of interaction of `font-lock' and syntaxification may be not cleaned
up yet. You may get slightly different colors basing on the order of
fontification and syntaxification. Say, the initial faces is correct,
but editing the buffer breaks this.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>. (`Perl doc', `Regexp'): New submenus (latter to allow short displays). (cperl-clobber-lisp-bindings): New cfg variable. (cperl-find-pods-heres): $a->y() is not y///.

(cperl-electric-keyword): print a message, governed by `cperl-message-electric-keyword'. (cperl-electric-paren): Typing `}' was not checking for being block or not. (cperl-beautify-regexp-piece): Did not know about lookbehind; finding *which* level to work with was not intuitive. (cperl-beautify-levels): New command. (cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command. (cperl-invert-if-unless): New command (C-c C-t and in Menu). (cperl-hints): mention 20.2's goods/bads. (cperl-extra-newline-before-brace-multiline): Started to use it.

Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric.

Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated. (cperl-toggle-construct-fix): New command. Added on C-c C-w and menu. (auto-fill-mode): added on C-c C-f and menu. (cperl-style-alist): `PerlStyle' style added.

Even with older Emacsen CPerl mode tries to corrects some Emacs
misunderstandings, however, for efficiency reasons the degree of
correction is different for different operations. The partially
corrected problems are: POD sections, here-documents, regexps. The
operations are: highlighting, indentation, electric keywords, electric

Backslash cleanup in Elisp source files This patch should not change behavior. It typically omits backslashes where they are redundant (e.g., in the string literal "^\$"). In a few places, insert backslashes where they make regular expressions clearer: e.g., replace "^\*" (equivalent to "^*") with "^\\*", which has the same effect as a regular expression. Also, use ‘\ %’ instead of ‘\%’ when avoiding confusion with SCCS IDs, and similarly use ‘\ $’ instead of ‘\$’ when avoiding confusion with RCS IDs, as that makes it clearer that the backslash is intended.

should work if the balance of delimiters is not broken by POD).
The main trick (to make $ a \"backslash\") makes constructions like
${aaa} look like unbalanced braces. The only trick I can think of is
* progmodes/cperl-mode.el, progmodes/idlw-shell.el, progmodes/idlwave.el, progmodes/vhdl-mode.el: Replace `legal' with `valid'.

Similar problems arise in regexps, when /(\\s|$)/ should be rewritten
(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>. (`Perl doc', `Regexp'): New submenus (latter to allow short displays). (cperl-clobber-lisp-bindings): New cfg variable. (cperl-find-pods-heres): $a->y() is not y///. (cperl-after-block-p): Add save-excursion. (cperl-init-faces): Was failing. Init faces when loading `ps-print'. (cperl-toggle-autohelp): New command.

(cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'.

(cperl-break-one-line-blocks-when-indent): New cfg variable. (cperl-fix-hanging-brace-when-indent): New cfg variable. (cperl-merge-trailing-else): New cfg variable. Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too.

Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated. (cperl-toggle-construct-fix): New command. Added on C-c C-w and menu. (auto-fill-mode): added on C-c C-f and menu. (cperl-style-alist): `PerlStyle' style added.

Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx.

Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early.

(cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?).

Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'.

(cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28.

(cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'.

q) Can ispell POD sections and HERE-DOCs.
r) Understands comments and character classes inside regular
expressions; can find matching () and [] in a regular expression.
s) Allows indentation of //x-style regular expressions;
t) Highlights different symbols in regular expressions according
to their function; much less problems with backslashitis;
u) Allows to find regular expressions which contain interpolated parts.
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx.

(cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

5) The indentation engine was very smart, but most of tricks may be
not needed anymore with the support for `syntax-table' property. Has
progress indicator for indentation (with `imenu' loaded).
(cperl-invalid-face): double-quote underline
2000-10-11 16:53:24 +00:00
6) Indent-region improves inline-comments as well; also corrects
(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>.

(cperl-electric-keyword): `foreachmy', `formy' expanded too, Expands `=pod-directive'. (cperl-linefeed): behaves reasonable in POD-directive lines. (cperl-message-electric-keyword): new cfg variable. (cperl-electric-keyword): print a message, governed by `cperl-message-electric-keyword'. (cperl-electric-paren): Typing `}' was not checking for being block or not. (cperl-beautify-regexp-piece): Did not know about lookbehind; finding *which* level to work with was not intuitive. (cperl-beautify-levels): New command. (cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command. (cperl-invert-if-unless): New command (C-c C-t and in Menu). (cperl-hints): mention 20.2's goods/bads. (cperl-extra-newline-before-brace-multiline): Started to use it.

Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric. (cperl-electric-keyword): Electric `do' inserts `do/while'. (cperl-fontify-syntaxically): New function. (cperl-syntaxify-by-font-lock): New cfg variable. Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated. (cperl-toggle-construct-fix): New command. Added on C-c C-w and menu. (auto-fill-mode): added on C-c C-f and menu. (cperl-style-alist): `PerlStyle' style added.

"This is an incomplete compendium of what is available in other parts
of CPerl documentation. (Please inform me if I skept anything.)
There is a perception that CPerl is slower than alternatives. This part
of documentation is designed to overcome this misconception.
*By default* CPerl tries to enable the most comfortable settings.
From most points of view, correctly working package is infinitely more
comfortable than a non-correctly working one, thus by default CPerl
prefers correctness over speed. Below is the guide how to change
settings if your preferences are different.
A) Speed of loading the file. When loading file, CPerl may perform a
scan which indicates places which cannot be parsed by primitive Emacs
syntax-parsing routines, and marks them up so that either
A1) CPerl may work around these deficiencies (for big chunks, mostly
PODs and HERE-documents), or

One can add a (minor) speedup to editing operations by setting
`cperl-use-syntax-table-text-property'
variable to nil (if it is set to t). This will disable
syntax-engine-helping scan, thus will make many more Perl
constructs be wrongly recognized by CPerl, thus may lead to
wrongly matched parentheses, wrong indentation, etc.

Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine.

Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too.

`font-lock-constant-face' HERE-doc delimiters, labels, delimiters of
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state.

(cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

Summary of most visible changes: ;; a) Multiple <<HERE per line allowed. ;; b) Handles multiline subroutine declaration headers (with comments). ;; (The exception is `cperl-etags' - but it is not used in the rest ;; of the mode.) ;; c) Fontifies multiline my/our declarations (even with comments, ;; and with legacy `font-lock'). ;; d) Major speedup of syntaxification, both immediate and postponed ;; (3.5x to 15x [for different CPUs and versions of Emacs] on the ;; huge real-life document I tested). ;; e) New bindings, edits to imenu. ;; f) "_" is made into word-char during fontification/syntaxification; ;; some attempts to recognize non-word "_" during other operations too. ;; g) Detect bug in Emacs with `looking-at' inside `narrow' and bulk out. ;; h) autoload some more perldoc-related stuff ;; i) Some new convenience features: ISpell POD/HEREDOCs, narrow-to-HEREDOC ;; j) Attempt to incorporate XEmacs edits which reached me Fine-grained changelog: `cperl-hook-after-change': New configuration variable `cperl-vc-sccs-header': Likewise. `cperl-vc-sccs-header': Likewise. `cperl-vc-header-alist': Default via two preceding variables `cperl-invalid-face': Remove double quoting under XEmacs (still needed under 21.2) `cperl-tips': Update URLs for resources `cperl-problems': Likewise. `cperl-praise': Mention new features New C-c key bindings: for `cperl-find-bad-style', `cperl-pod-spell', `cperl-here-doc-spell', `cperl-narrow-to-here-doc', `cperl-perdoc', `cperl-perldoc-at-point' CPerl Mode menu changes: "Fix style by spaces", "Imenu on Perl Info" moved, new submenu of Tools with Ispell entries and narrowing. `cperl-after-sub-regexp': New defsubst `cperl-imenu--function-name-regexp-perl': Use `cperl-after-sub-regexp', Allows heads up to head4 Allow "package;" `defun-prompt-regexp': Use `cperl-after-sub-regexp', `paren-backwards-message': ???

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>. (`Perl doc', `Regexp'): New submenus (latter to allow short displays). (cperl-clobber-lisp-bindings): New cfg variable. (cperl-find-pods-heres): $a->y() is not y///. (cperl-after-block-p): Add save-excursion. (cperl-init-faces): Was failing. Init faces when loading `ps-print'. (cperl-toggle-autohelp): New command. (cperl-electric-paren): `while SPACE LESS' was buggy. (cperl-init-faces): `-text' in `[-text => 1]' was not highlighted. (cperl-after-block-p): was FALSE after `sub f {}'. (cperl-electric-keyword): `foreachmy', `formy' expanded too, Expands `=pod-directive'. (cperl-linefeed): behaves reasonable in POD-directive lines. (cperl-message-electric-keyword): new cfg variable. (cperl-electric-keyword): print a message, governed by `cperl-message-electric-keyword'. (cperl-electric-paren): Typing `}' was not checking for being block or not. (cperl-beautify-regexp-piece): Did not know about lookbehind; finding *which* level to work with was not intuitive. (cperl-beautify-levels): New command. (cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command. (cperl-invert-if-unless): New command (C-c C-t and in Menu). (cperl-hints): mention 20.2's goods/bads. (cperl-extra-newline-before-brace-multiline): Started to use it. (cperl-break-one-line-blocks-when-indent): New cfg variable. (cperl-fix-hanging-brace-when-indent): New cfg variable. (cperl-merge-trailing-else): New cfg variable. Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric. (cperl-electric-keyword): Electric `do' inserts `do/while'. (cperl-fontify-syntaxically): New function. (cperl-syntaxify-by-font-lock): New cfg variable. Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated. (cperl-toggle-construct-fix): New command. Added on C-c C-w and menu. (auto-fill-mode): added on C-c C-f and menu. (cperl-style-alist): `PerlStyle' style added.

'(' after keyword would insert a doubled paren. (cperl-calculate-indent): Update syntaxification before checks. Fix wrong indent of blocks starting with POD. (cperl-find-pods-heres): If no end of HERE-doc found, mark to the end of buffer. This enables recognition of end of HERE-doc "as one types". Require "\n" after trailing tag of HERE-doc. \( made non-quoting outside of string/comment (gdj-contributed). Likewise for \$. Remove `here-doc-group' text property at start (makes this property reliable). Text property `first-format-line' ==> t. Do not recognize $opt_s and $opt::s as s///. (cperl-after-block-p): Optional arg pre-block to check for a pre-block Recognize `continue' blocks too. (cperl-after-expr-p): Update syntaxification before checks. Work after here-docs, formats, and PODs too (affects many electric constructs). (cperl-fix-line-spacing): Allow "_" in $vars of foreach etc. (cperl-perldoc): Use case-sensitive search.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>.

(cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command.

(cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too.

(cperl-electric-paren): `while SPACE LESS' was buggy. (cperl-init-faces): `-text' in `[-text => 1]' was not highlighted. (cperl-after-block-p): was FALSE after `sub f {}'. (cperl-electric-keyword): `foreachmy', `formy' expanded too, Expands `=pod-directive'. (cperl-linefeed): behaves reasonable in POD-directive lines. (cperl-message-electric-keyword): new cfg variable.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>. (`Perl doc', `Regexp'): New submenus (latter to allow short displays). (cperl-clobber-lisp-bindings): New cfg variable. (cperl-find-pods-heres): $a->y() is not y///. (cperl-after-block-p): Add save-excursion. (cperl-init-faces): Was failing. Init faces when loading `ps-print'. (cperl-toggle-autohelp): New command. (cperl-electric-paren): `while SPACE LESS' was buggy. (cperl-init-faces): `-text' in `[-text => 1]' was not highlighted. (cperl-after-block-p): was FALSE after `sub f {}'. (cperl-electric-keyword): `foreachmy', `formy' expanded too, Expands `=pod-directive'. (cperl-linefeed): behaves reasonable in POD-directive lines. (cperl-message-electric-keyword): new cfg variable. (cperl-electric-keyword): print a message, governed by `cperl-message-electric-keyword'. (cperl-electric-paren): Typing `}' was not checking for being block or not. (cperl-beautify-regexp-piece): Did not know about lookbehind; finding *which* level to work with was not intuitive. (cperl-beautify-levels): New command. (cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command. (cperl-invert-if-unless): New command (C-c C-t and in Menu). (cperl-hints): mention 20.2's goods/bads. (cperl-extra-newline-before-brace-multiline): Started to use it. (cperl-break-one-line-blocks-when-indent): New cfg variable. (cperl-fix-hanging-brace-when-indent): New cfg variable. (cperl-merge-trailing-else): New cfg variable. Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric. (cperl-electric-keyword): Electric `do' inserts `do/while'. (cperl-fontify-syntaxically): New function. (cperl-syntaxify-by-font-lock): New cfg variable. Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated. (cperl-toggle-construct-fix): New command. Added on C-c C-w and menu. (auto-fill-mode): added on C-c C-f and menu. (cperl-style-alist): `PerlStyle' style added. (cperl-find-pods-heres): Message for termination of scan corrected. (cperl-speed): New variable with hints. (cperl-electric-else): Make backspace electric after expansion of `else/continue' too. Fixed customization to honor cperl-hairy. Created customization groups. All the compile-time warnings fixed. (cperl-syntaxify-by-font-lock): Interaction with `font-lock-hot-pass' fixed. (cperl-after-block-and-statement-beg): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p, cperl-after-expr-p): Likewise. (cperl-indent-region): Make a marker for END - text added/removed. (cperl-style-alist): Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-tips, cperl-problems): Improvements to docs.

CPerl knows several indentation styles, and may bulk set the
corresponding variables. Use \\[cperl-set-style] to do this. Use
\\[cperl-set-style-back] to restore the memorized preexisting values

Merge from upstream, upto version 5.22. After 5.0: `cperl-add-tags-recurse-noxs-fullpath': new function (for -batch mode) After 5.1: ;; Major edit. Summary of most visible changes: ;; a) Multiple <<HERE per line allowed. ;; b) Handles multiline subroutine declaration headers (with comments). ;; (The exception is `cperl-etags' - but it is not used in the rest ;; of the mode.) ;; c) Fontifies multiline my/our declarations (even with comments, ;; and with legacy `font-lock'). ;; d) Major speedup of syntaxification, both immediate and postponed ;; (3.5x to 15x [for different CPUs and versions of Emacs] on the ;; huge real-life document I tested). ;; e) New bindings, edits to imenu. ;; f) "_" is made into word-char during fontification/syntaxification; ;; some attempts to recognize non-word "_" during other operations too. ;; g) Detect bug in Emacs with `looking-at' inside `narrow' and bulk out. ;; h) autoload some more perldoc-related stuff ;; i) Some new convenience features: ISpell POD/HEREDOCs, narrow-to-HEREDOC ;; j) Attempt to incorporate XEmacs edits which reached me Fine-grained changelog: `cperl-hook-after-change': New configuration variable `cperl-vc-sccs-header': Likewise. `cperl-vc-sccs-header': Likewise. `cperl-vc-header-alist': Default via two preceding variables `cperl-invalid-face': Remove double quoting under XEmacs (still needed under 21.2) `cperl-tips': Update URLs for resources `cperl-problems': Likewise. `cperl-praise': Mention new features New C-c key bindings: for `cperl-find-bad-style', `cperl-pod-spell', `cperl-here-doc-spell', `cperl-narrow-to-here-doc', `cperl-perdoc', `cperl-perldoc-at-point' CPerl Mode menu changes: "Fix style by spaces", "Imenu on Perl Info" moved, new submenu of Tools with Ispell entries and narrowing. `cperl-after-sub-regexp': New defsubst `cperl-imenu--function-name-regexp-perl': Use `cperl-after-sub-regexp', Allows heads up to head4 Allow "package;" `defun-prompt-regexp': Use `cperl-after-sub-regexp', `paren-backwards-message': ???

(or cperl-syntaxify-by-font-lock
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'.

(progn ; Too naive???
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

(cperl-mode) <defun-prompt_regexp>: Understand prototypes. (cperl-electric-brace): Use `cperl-after-block-p' for detection. (cperl-electric-keyword): Make $if (etc: "$@%&*") non-electric. '(' after keyword would insert a doubled paren. (cperl-calculate-indent): Update syntaxification before checks. Fix wrong indent of blocks starting with POD. (cperl-find-pods-heres): If no end of HERE-doc found, mark to the end of buffer. This enables recognition of end of HERE-doc "as one types". Require "\n" after trailing tag of HERE-doc. \( made non-quoting outside of string/comment (gdj-contributed). Likewise for \$. Remove `here-doc-group' text property at start (makes this property reliable). Text property `first-format-line' ==> t. Do not recognize $opt_s and $opt::s as s///. (cperl-after-block-p): Optional arg pre-block to check for a pre-block Recognize `continue' blocks too. (cperl-after-expr-p): Update syntaxification before checks. Work after here-docs, formats, and PODs too (affects many electric constructs). (cperl-fix-line-spacing): Allow "_" in $vars of foreach etc. (cperl-perldoc): Use case-sensitive search.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

'(' after keyword would insert a doubled paren. (cperl-calculate-indent): Update syntaxification before checks. Fix wrong indent of blocks starting with POD. (cperl-find-pods-heres): If no end of HERE-doc found, mark to the end of buffer. This enables recognition of end of HERE-doc "as one types". Require "\n" after trailing tag of HERE-doc. \( made non-quoting outside of string/comment (gdj-contributed). Likewise for \$. Remove `here-doc-group' text property at start (makes this property reliable). Text property `first-format-line' ==> t. Do not recognize $opt_s and $opt::s as s///. (cperl-after-block-p): Optional arg pre-block to check for a pre-block Recognize `continue' blocks too. (cperl-after-expr-p): Update syntaxification before checks.

Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx.

(cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state.

(cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

(cperl-find-pods-heres): If no end of HERE-doc found, mark to the end of buffer. This enables recognition of end of HERE-doc "as one types". Require "\n" after trailing tag of HERE-doc. \( made non-quoting outside of string/comment (gdj-contributed). Likewise for \$. Remove `here-doc-group' text property at start (makes this property reliable). Text property `first-format-line' ==> t. Do not recognize $opt_s and $opt::s as s///. (cperl-after-block-p): Optional arg pre-block to check for a pre-block Recognize `continue' blocks too. (cperl-after-expr-p): Update syntaxification before checks.

(cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine.

Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def.

(cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'.

(cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed.

indent i shift-amt)
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro.

(cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'.

(cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?).

message if needed. If SET-ST is non-nil, will use (or generate) a
cached syntax table in ST-L. If ERR-L is non-nil, will store the
error message in its CAR (unless it already contains some error

(setq b (point)
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx.

Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks.

(cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements.

(cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'.

Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE.

(while (and end (< end (point-max))
(get-text-property end 'syntax-type))
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time.

(cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>. (`Perl doc', `Regexp'): New submenus (latter to allow short displays). (cperl-clobber-lisp-bindings): New cfg variable. (cperl-find-pods-heres): $a->y() is not y///. (cperl-after-block-p): Add save-excursion. (cperl-init-faces): Was failing. Init faces when loading `ps-print'. (cperl-toggle-autohelp): New command. (cperl-electric-paren): `while SPACE LESS' was buggy. (cperl-init-faces): `-text' in `[-text => 1]' was not highlighted. (cperl-after-block-p): was FALSE after `sub f {}'. (cperl-electric-keyword): `foreachmy', `formy' expanded too, Expands `=pod-directive'. (cperl-linefeed): behaves reasonable in POD-directive lines. (cperl-message-electric-keyword): new cfg variable. (cperl-electric-keyword): print a message, governed by `cperl-message-electric-keyword'. (cperl-electric-paren): Typing `}' was not checking for being block or not. (cperl-beautify-regexp-piece): Did not know about lookbehind; finding *which* level to work with was not intuitive. (cperl-beautify-levels): New command. (cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command. (cperl-invert-if-unless): New command (C-c C-t and in Menu). (cperl-hints): mention 20.2's goods/bads. (cperl-extra-newline-before-brace-multiline): Started to use it. (cperl-break-one-line-blocks-when-indent): New cfg variable. (cperl-fix-hanging-brace-when-indent): New cfg variable. (cperl-merge-trailing-else): New cfg variable. Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric. (cperl-electric-keyword): Electric `do' inserts `do/while'. (cperl-fontify-syntaxically): New function. (cperl-syntaxify-by-font-lock): New cfg variable. Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated. (cperl-toggle-construct-fix): New command. Added on C-c C-w and menu. (auto-fill-mode): added on C-c C-f and menu. (cperl-style-alist): `PerlStyle' style added. (cperl-find-pods-heres): Message for termination of scan corrected. (cperl-speed): New variable with hints. (cperl-electric-else): Make backspace electric after expansion of `else/continue' too.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>. (`Perl doc', `Regexp'): New submenus (latter to allow short displays). (cperl-clobber-lisp-bindings): New cfg variable. (cperl-find-pods-heres): $a->y() is not y///. (cperl-after-block-p): Add save-excursion. (cperl-init-faces): Was failing. Init faces when loading `ps-print'. (cperl-toggle-autohelp): New command. (cperl-electric-paren): `while SPACE LESS' was buggy. (cperl-init-faces): `-text' in `[-text => 1]' was not highlighted. (cperl-after-block-p): was FALSE after `sub f {}'.

(cperl-electric-keyword): print a message, governed by `cperl-message-electric-keyword'. (cperl-electric-paren): Typing `}' was not checking for being block or not. (cperl-beautify-regexp-piece): Did not know about lookbehind; finding *which* level to work with was not intuitive. (cperl-beautify-levels): New command. (cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command. (cperl-invert-if-unless): New command (C-c C-t and in Menu). (cperl-hints): mention 20.2's goods/bads. (cperl-extra-newline-before-brace-multiline): Started to use it. (cperl-break-one-line-blocks-when-indent): New cfg variable. (cperl-fix-hanging-brace-when-indent): New cfg variable. (cperl-merge-trailing-else): New cfg variable. Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric. (cperl-electric-keyword): Electric `do' inserts `do/while'. (cperl-fontify-syntaxically): New function. (cperl-syntaxify-by-font-lock): New cfg variable. Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated. (cperl-toggle-construct-fix): New command. Added on C-c C-w and menu. (auto-fill-mode): added on C-c C-f and menu. (cperl-style-alist): `PerlStyle' style added.

Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx.

Merge changes from CPerl-5.0. (toplevel): Require man. (condition-case): Don't autoload tmm-prompt (it's in loaddefs.el). (cperl-electric-backspace-untabify): New var. (cperl-electric-backspace): Use it. (cperl-vc-header-alist): Extract numeric version from the Id. (cperl-build-manpage): New fun. (cperl-menu): Use it. Add toggle-autohelp. (cperl-mode) <defun-prompt_regexp>: Understand prototypes. (cperl-electric-brace): Use `cperl-after-block-p' for detection. (cperl-electric-keyword): Make $if (etc: "$@%&*") non-electric. '(' after keyword would insert a doubled paren. (cperl-calculate-indent): Update syntaxification before checks. Fix wrong indent of blocks starting with POD. (cperl-find-pods-heres): If no end of HERE-doc found, mark to the end of buffer. This enables recognition of end of HERE-doc "as one types". Require "\n" after trailing tag of HERE-doc. \( made non-quoting outside of string/comment (gdj-contributed). Likewise for \$. Remove `here-doc-group' text property at start (makes this property reliable). Text property `first-format-line' ==> t. Do not recognize $opt_s and $opt::s as s///. (cperl-after-block-p): Optional arg pre-block to check for a pre-block Recognize `continue' blocks too. (cperl-after-expr-p): Update syntaxification before checks. Work after here-docs, formats, and PODs too (affects many electric constructs). (cperl-fix-line-spacing): Allow "_" in $vars of foreach etc. (cperl-perldoc): Use case-sensitive search.

Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>.

(cperl-electric-keyword): `foreachmy', `formy' expanded too, Expands `=pod-directive'. (cperl-linefeed): behaves reasonable in POD-directive lines. (cperl-message-electric-keyword): new cfg variable. (cperl-electric-keyword): print a message, governed by `cperl-message-electric-keyword'. (cperl-electric-paren): Typing `}' was not checking for being block or not. (cperl-beautify-regexp-piece): Did not know about lookbehind; finding *which* level to work with was not intuitive. (cperl-beautify-levels): New command. (cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'.

(cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx.

(cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'.

(cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28.

Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>.

(cperl-electric-keyword): print a message, governed by `cperl-message-electric-keyword'. (cperl-electric-paren): Typing `}' was not checking for being block or not. (cperl-beautify-regexp-piece): Did not know about lookbehind; finding *which* level to work with was not intuitive. (cperl-beautify-levels): New command. (cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command. (cperl-invert-if-unless): New command (C-c C-t and in Menu). (cperl-hints): mention 20.2's goods/bads. (cperl-extra-newline-before-brace-multiline): Started to use it. (cperl-break-one-line-blocks-when-indent): New cfg variable. (cperl-fix-hanging-brace-when-indent): New cfg variable. (cperl-merge-trailing-else): New cfg variable. Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric. (cperl-electric-keyword): Electric `do' inserts `do/while'. (cperl-fontify-syntaxically): New function. (cperl-syntaxify-by-font-lock): New cfg variable. Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated. (cperl-toggle-construct-fix): New command. Added on C-c C-w and menu. (auto-fill-mode): added on C-c C-f and menu. (cperl-style-alist): `PerlStyle' style added.

Merge changes from CPerl-5.0. (toplevel): Require man. (condition-case): Don't autoload tmm-prompt (it's in loaddefs.el). (cperl-electric-backspace-untabify): New var. (cperl-electric-backspace): Use it. (cperl-vc-header-alist): Extract numeric version from the Id. (cperl-build-manpage): New fun. (cperl-menu): Use it. Add toggle-autohelp.

'(' after keyword would insert a doubled paren. (cperl-calculate-indent): Update syntaxification before checks. Fix wrong indent of blocks starting with POD. (cperl-find-pods-heres): If no end of HERE-doc found, mark to the end of buffer. This enables recognition of end of HERE-doc "as one types". Require "\n" after trailing tag of HERE-doc. \( made non-quoting outside of string/comment (gdj-contributed). Likewise for \$. Remove `here-doc-group' text property at start (makes this property reliable). Text property `first-format-line' ==> t. Do not recognize $opt_s and $opt::s as s///. (cperl-after-block-p): Optional arg pre-block to check for a pre-block Recognize `continue' blocks too. (cperl-after-expr-p): Update syntaxification before checks. Work after here-docs, formats, and PODs too (affects many electric constructs). (cperl-fix-line-spacing): Allow "_" in $vars of foreach etc. (cperl-perldoc): Use case-sensitive search.

(cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE.

(setq b (point)
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine.

Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early.

(cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>. (`Perl doc', `Regexp'): New submenus (latter to allow short displays). (cperl-clobber-lisp-bindings): New cfg variable. (cperl-find-pods-heres): $a->y() is not y///. (cperl-after-block-p): Add save-excursion. (cperl-init-faces): Was failing. Init faces when loading `ps-print'. (cperl-toggle-autohelp): New command. (cperl-electric-paren): `while SPACE LESS' was buggy. (cperl-init-faces): `-text' in `[-text => 1]' was not highlighted. (cperl-after-block-p): was FALSE after `sub f {}'. (cperl-electric-keyword): `foreachmy', `formy' expanded too, Expands `=pod-directive'. (cperl-linefeed): behaves reasonable in POD-directive lines. (cperl-message-electric-keyword): new cfg variable. (cperl-electric-keyword): print a message, governed by `cperl-message-electric-keyword'. (cperl-electric-paren): Typing `}' was not checking for being block or not. (cperl-beautify-regexp-piece): Did not know about lookbehind; finding *which* level to work with was not intuitive. (cperl-beautify-levels): New command. (cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command. (cperl-invert-if-unless): New command (C-c C-t and in Menu). (cperl-hints): mention 20.2's goods/bads. (cperl-extra-newline-before-brace-multiline): Started to use it. (cperl-break-one-line-blocks-when-indent): New cfg variable. (cperl-fix-hanging-brace-when-indent): New cfg variable. (cperl-merge-trailing-else): New cfg variable. Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric. (cperl-electric-keyword): Electric `do' inserts `do/while'. (cperl-fontify-syntaxically): New function. (cperl-syntaxify-by-font-lock): New cfg variable. Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated. (cperl-toggle-construct-fix): New command. Added on C-c C-w and menu. (auto-fill-mode): added on C-c C-f and menu. (cperl-style-alist): `PerlStyle' style added. (cperl-find-pods-heres): Message for termination of scan corrected. (cperl-speed): New variable with hints. (cperl-electric-else): Make backspace electric after expansion of `else/continue' too.

(cperl-after-block-and-statement-beg): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p, cperl-after-expr-p): Likewise. (cperl-indent-region): Make a marker for END - text added/removed. (cperl-style-alist): Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-tips, cperl-problems): Improvements to docs.

(cperl-mode) <defun-prompt_regexp>: Understand prototypes. (cperl-electric-brace): Use `cperl-after-block-p' for detection. (cperl-electric-keyword): Make $if (etc: "$@%&*") non-electric. '(' after keyword would insert a doubled paren. (cperl-calculate-indent): Update syntaxification before checks. Fix wrong indent of blocks starting with POD. (cperl-find-pods-heres): If no end of HERE-doc found, mark to the end of buffer. This enables recognition of end of HERE-doc "as one types". Require "\n" after trailing tag of HERE-doc. \( made non-quoting outside of string/comment (gdj-contributed). Likewise for \$. Remove `here-doc-group' text property at start (makes this property reliable). Text property `first-format-line' ==> t. Do not recognize $opt_s and $opt::s as s///. (cperl-after-block-p): Optional arg pre-block to check for a pre-block Recognize `continue' blocks too. (cperl-after-expr-p): Update syntaxification before checks.

Merge changes from CPerl-5.0. (toplevel): Require man. (condition-case): Don't autoload tmm-prompt (it's in loaddefs.el). (cperl-electric-backspace-untabify): New var. (cperl-electric-backspace): Use it. (cperl-vc-header-alist): Extract numeric version from the Id. (cperl-build-manpage): New fun. (cperl-menu): Use it. Add toggle-autohelp. (cperl-mode) <defun-prompt_regexp>: Understand prototypes. (cperl-electric-brace): Use `cperl-after-block-p' for detection. (cperl-electric-keyword): Make $if (etc: "$@%&*") non-electric. '(' after keyword would insert a doubled paren. (cperl-calculate-indent): Update syntaxification before checks. Fix wrong indent of blocks starting with POD. (cperl-find-pods-heres): If no end of HERE-doc found, mark to the end of buffer. This enables recognition of end of HERE-doc "as one types". Require "\n" after trailing tag of HERE-doc. \( made non-quoting outside of string/comment (gdj-contributed). Likewise for \$. Remove `here-doc-group' text property at start (makes this property reliable). Text property `first-format-line' ==> t. Do not recognize $opt_s and $opt::s as s///. (cperl-after-block-p): Optional arg pre-block to check for a pre-block Recognize `continue' blocks too. (cperl-after-expr-p): Update syntaxification before checks. Work after here-docs, formats, and PODs too (affects many electric constructs). (cperl-fix-line-spacing): Allow "_" in $vars of foreach etc. (cperl-perldoc): Use case-sensitive search.

Merge changes from CPerl-5.0. (toplevel): Require man. (condition-case): Don't autoload tmm-prompt (it's in loaddefs.el). (cperl-electric-backspace-untabify): New var. (cperl-electric-backspace): Use it. (cperl-vc-header-alist): Extract numeric version from the Id. (cperl-build-manpage): New fun. (cperl-menu): Use it. Add toggle-autohelp. (cperl-mode) <defun-prompt_regexp>: Understand prototypes. (cperl-electric-brace): Use `cperl-after-block-p' for detection. (cperl-electric-keyword): Make $if (etc: "$@%&*") non-electric. '(' after keyword would insert a doubled paren. (cperl-calculate-indent): Update syntaxification before checks. Fix wrong indent of blocks starting with POD. (cperl-find-pods-heres): If no end of HERE-doc found, mark to the end of buffer. This enables recognition of end of HERE-doc "as one types". Require "\n" after trailing tag of HERE-doc. \( made non-quoting outside of string/comment (gdj-contributed). Likewise for \$. Remove `here-doc-group' text property at start (makes this property reliable). Text property `first-format-line' ==> t. Do not recognize $opt_s and $opt::s as s///. (cperl-after-block-p): Optional arg pre-block to check for a pre-block Recognize `continue' blocks too. (cperl-after-expr-p): Update syntaxification before checks. Work after here-docs, formats, and PODs too (affects many electric constructs). (cperl-fix-line-spacing): Allow "_" in $vars of foreach etc. (cperl-perldoc): Use case-sensitive search.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

(cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

'(' after keyword would insert a doubled paren. (cperl-calculate-indent): Update syntaxification before checks. Fix wrong indent of blocks starting with POD. (cperl-find-pods-heres): If no end of HERE-doc found, mark to the end of buffer. This enables recognition of end of HERE-doc "as one types". Require "\n" after trailing tag of HERE-doc. \( made non-quoting outside of string/comment (gdj-contributed). Likewise for \$. Remove `here-doc-group' text property at start (makes this property reliable). Text property `first-format-line' ==> t. Do not recognize $opt_s and $opt::s as s///. (cperl-after-block-p): Optional arg pre-block to check for a pre-block Recognize `continue' blocks too. (cperl-after-expr-p): Update syntaxification before checks. Work after here-docs, formats, and PODs too (affects many electric constructs). (cperl-fix-line-spacing): Allow "_" in $vars of foreach etc. (cperl-perldoc): Use case-sensitive search.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

(cperl-mode) <defun-prompt_regexp>: Understand prototypes. (cperl-electric-brace): Use `cperl-after-block-p' for detection. (cperl-electric-keyword): Make $if (etc: "$@%&*") non-electric. '(' after keyword would insert a doubled paren. (cperl-calculate-indent): Update syntaxification before checks. Fix wrong indent of blocks starting with POD. (cperl-find-pods-heres): If no end of HERE-doc found, mark to the end of buffer. This enables recognition of end of HERE-doc "as one types". Require "\n" after trailing tag of HERE-doc. \( made non-quoting outside of string/comment (gdj-contributed). Likewise for \$. Remove `here-doc-group' text property at start (makes this property reliable). Text property `first-format-line' ==> t. Do not recognize $opt_s and $opt::s as s///. (cperl-after-block-p): Optional arg pre-block to check for a pre-block Recognize `continue' blocks too. (cperl-after-expr-p): Update syntaxification before checks. Work after here-docs, formats, and PODs too (affects many electric constructs). (cperl-fix-line-spacing): Allow "_" in $vars of foreach etc. (cperl-perldoc): Use case-sensitive search.

;; Commenting \\ is dangerous, what about ( ?
(and i tail
(eq (char-after i) ?\\)
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks.

Backslash cleanup in Elisp source files This patch should not change behavior. It typically omits backslashes where they are redundant (e.g., in the string literal "^\$"). In a few places, insert backslashes where they make regular expressions clearer: e.g., replace "^\*" (equivalent to "^*") with "^\\*", which has the same effect as a regular expression. Also, use ‘\ %’ instead of ‘\%’ when avoiding confusion with SCCS IDs, and similarly use ‘\ $’ instead of ‘\$’ when avoiding confusion with RCS IDs, as that makes it clearer that the backslash is intended.

Backslash cleanup in Elisp source files This patch should not change behavior. It typically omits backslashes where they are redundant (e.g., in the string literal "^\$"). In a few places, insert backslashes where they make regular expressions clearer: e.g., replace "^\*" (equivalent to "^*") with "^\\*", which has the same effect as a regular expression. Also, use ‘\ %’ instead of ‘\%’ when avoiding confusion with SCCS IDs, and similarly use ‘\ $’ instead of ‘\$’ when avoiding confusion with RCS IDs, as that makes it clearer that the backslash is intended.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd.

(cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string.

Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx.

(cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro.

(skip-chars-backward " \t\n\f" lim)
(setq p (point))
(beginning-of-line)
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

;; What is the difference of (cperl-after-block-p lim t) and (cperl-block-p)?
;; No save-excursion; condition-case ... In (cperl-block-p) the block
;; may be a part of an in-statement construct, such as
;; ${something()}, print {FH} $data.
;; Moreover, one takes positive approach (looks for else,grep etc)
;; another negative (looks for bless,tr etc)
Merge changes from CPerl-5.0. (toplevel): Require man. (condition-case): Don't autoload tmm-prompt (it's in loaddefs.el). (cperl-electric-backspace-untabify): New var. (cperl-electric-backspace): Use it. (cperl-vc-header-alist): Extract numeric version from the Id. (cperl-build-manpage): New fun. (cperl-menu): Use it. Add toggle-autohelp. (cperl-mode) <defun-prompt_regexp>: Understand prototypes. (cperl-electric-brace): Use `cperl-after-block-p' for detection. (cperl-electric-keyword): Make $if (etc: "$@%&*") non-electric. '(' after keyword would insert a doubled paren. (cperl-calculate-indent): Update syntaxification before checks. Fix wrong indent of blocks starting with POD. (cperl-find-pods-heres): If no end of HERE-doc found, mark to the end of buffer. This enables recognition of end of HERE-doc "as one types". Require "\n" after trailing tag of HERE-doc. \( made non-quoting outside of string/comment (gdj-contributed). Likewise for \$. Remove `here-doc-group' text property at start (makes this property reliable). Text property `first-format-line' ==> t. Do not recognize $opt_s and $opt::s as s///. (cperl-after-block-p): Optional arg pre-block to check for a pre-block Recognize `continue' blocks too. (cperl-after-expr-p): Update syntaxification before checks. Work after here-docs, formats, and PODs too (affects many electric constructs). (cperl-fix-line-spacing): Allow "_" in $vars of foreach etc. (cperl-perldoc): Use case-sensitive search.

Would not look before LIM. Assumes that LIM is a good place to begin a
statement. The kind of block we treat here is one after which a new
statement would start; thus the block in ${func()} does not count."

Merge changes from CPerl-5.0. (toplevel): Require man. (condition-case): Don't autoload tmm-prompt (it's in loaddefs.el). (cperl-electric-backspace-untabify): New var. (cperl-electric-backspace): Use it. (cperl-vc-header-alist): Extract numeric version from the Id. (cperl-build-manpage): New fun. (cperl-menu): Use it. Add toggle-autohelp. (cperl-mode) <defun-prompt_regexp>: Understand prototypes. (cperl-electric-brace): Use `cperl-after-block-p' for detection. (cperl-electric-keyword): Make $if (etc: "$@%&*") non-electric. '(' after keyword would insert a doubled paren. (cperl-calculate-indent): Update syntaxification before checks. Fix wrong indent of blocks starting with POD. (cperl-find-pods-heres): If no end of HERE-doc found, mark to the end of buffer. This enables recognition of end of HERE-doc "as one types". Require "\n" after trailing tag of HERE-doc. \( made non-quoting outside of string/comment (gdj-contributed). Likewise for \$. Remove `here-doc-group' text property at start (makes this property reliable). Text property `first-format-line' ==> t. Do not recognize $opt_s and $opt::s as s///. (cperl-after-block-p): Optional arg pre-block to check for a pre-block Recognize `continue' blocks too. (cperl-after-expr-p): Update syntaxification before checks. Work after here-docs, formats, and PODs too (affects many electric constructs). (cperl-fix-line-spacing): Allow "_" in $vars of foreach etc. (cperl-perldoc): Use case-sensitive search.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>. (`Perl doc', `Regexp'): New submenus (latter to allow short displays). (cperl-clobber-lisp-bindings): New cfg variable. (cperl-find-pods-heres): $a->y() is not y///. (cperl-after-block-p): Add save-excursion. (cperl-init-faces): Was failing. Init faces when loading `ps-print'. (cperl-toggle-autohelp): New command. (cperl-electric-paren): `while SPACE LESS' was buggy. (cperl-init-faces): `-text' in `[-text => 1]' was not highlighted. (cperl-after-block-p): was FALSE after `sub f {}'. (cperl-electric-keyword): `foreachmy', `formy' expanded too, Expands `=pod-directive'. (cperl-linefeed): behaves reasonable in POD-directive lines. (cperl-message-electric-keyword): new cfg variable. (cperl-electric-keyword): print a message, governed by `cperl-message-electric-keyword'. (cperl-electric-paren): Typing `}' was not checking for being block or not. (cperl-beautify-regexp-piece): Did not know about lookbehind; finding *which* level to work with was not intuitive. (cperl-beautify-levels): New command. (cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command. (cperl-invert-if-unless): New command (C-c C-t and in Menu). (cperl-hints): mention 20.2's goods/bads. (cperl-extra-newline-before-brace-multiline): Started to use it. (cperl-break-one-line-blocks-when-indent): New cfg variable. (cperl-fix-hanging-brace-when-indent): New cfg variable. (cperl-merge-trailing-else): New cfg variable. Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro.

"Simple variant of indentation of continued-sexp.
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

"\\|") ; Flow control
Backslash cleanup in Elisp source files This patch should not change behavior. It typically omits backslashes where they are redundant (e.g., in the string literal "^\$"). In a few places, insert backslashes where they make regular expressions clearer: e.g., replace "^\*" (equivalent to "^*") with "^\\*", which has the same effect as a regular expression. Also, use ‘\ %’ instead of ‘\%’ when avoiding confusion with SCCS IDs, and similarly use ‘\ $’ instead of ‘\$’ when avoiding confusion with RCS IDs, as that makes it clearer that the backslash is intended.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

Backslash cleanup in Elisp source files This patch should not change behavior. It typically omits backslashes where they are redundant (e.g., in the string literal "^\$"). In a few places, insert backslashes where they make regular expressions clearer: e.g., replace "^\*" (equivalent to "^*") with "^\\*", which has the same effect as a regular expression. Also, use ‘\ %’ instead of ‘\%’ when avoiding confusion with SCCS IDs, and similarly use ‘\ $’ instead of ‘\$’ when avoiding confusion with RCS IDs, as that makes it clearer that the backslash is intended.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>.

Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too.

(cperl-force-face cperl-nonoverridable-face
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro.

(copy-face 'font-lock-emphasized-face 'cperl-array-face))
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def.

(cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28.

(copy-face 'font-lock-other-type-face 'cperl-nonoverridable-face))
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable.

Summary of most visible changes: ;; a) Multiple <<HERE per line allowed. ;; b) Handles multiline subroutine declaration headers (with comments). ;; (The exception is `cperl-etags' - but it is not used in the rest ;; of the mode.) ;; c) Fontifies multiline my/our declarations (even with comments, ;; and with legacy `font-lock'). ;; d) Major speedup of syntaxification, both immediate and postponed ;; (3.5x to 15x [for different CPUs and versions of Emacs] on the ;; huge real-life document I tested). ;; e) New bindings, edits to imenu. ;; f) "_" is made into word-char during fontification/syntaxification; ;; some attempts to recognize non-word "_" during other operations too. ;; g) Detect bug in Emacs with `looking-at' inside `narrow' and bulk out. ;; h) autoload some more perldoc-related stuff ;; i) Some new convenience features: ISpell POD/HEREDOCs, narrow-to-HEREDOC ;; j) Attempt to incorporate XEmacs edits which reached me Fine-grained changelog: `cperl-hook-after-change': New configuration variable `cperl-vc-sccs-header': Likewise. `cperl-vc-sccs-header': Likewise. `cperl-vc-header-alist': Default via two preceding variables `cperl-invalid-face': Remove double quoting under XEmacs (still needed under 21.2) `cperl-tips': Update URLs for resources `cperl-problems': Likewise. `cperl-praise': Mention new features New C-c key bindings: for `cperl-find-bad-style', `cperl-pod-spell', `cperl-here-doc-spell', `cperl-narrow-to-here-doc', `cperl-perdoc', `cperl-perldoc-at-point' CPerl Mode menu changes: "Fix style by spaces", "Imenu on Perl Info" moved, new submenu of Tools with Ispell entries and narrowing. `cperl-after-sub-regexp': New defsubst `cperl-imenu--function-name-regexp-perl': Use `cperl-after-sub-regexp', Allows heads up to head4 Allow "package;" `defun-prompt-regexp': Use `cperl-after-sub-regexp', `paren-backwards-message': ???

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>. (`Perl doc', `Regexp'): New submenus (latter to allow short displays). (cperl-clobber-lisp-bindings): New cfg variable. (cperl-find-pods-heres): $a->y() is not y///. (cperl-after-block-p): Add save-excursion. (cperl-init-faces): Was failing. Init faces when loading `ps-print'. (cperl-toggle-autohelp): New command. (cperl-electric-paren): `while SPACE LESS' was buggy. (cperl-init-faces): `-text' in `[-text => 1]' was not highlighted. (cperl-after-block-p): was FALSE after `sub f {}'.

(cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command. (cperl-invert-if-unless): New command (C-c C-t and in Menu). (cperl-hints): mention 20.2's goods/bads. (cperl-extra-newline-before-brace-multiline): Started to use it.

Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric.

Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated. (cperl-toggle-construct-fix): New command. Added on C-c C-w and menu. (auto-fill-mode): added on C-c C-f and menu. (cperl-style-alist): `PerlStyle' style added.

(append '(cperl-array-face cperl-hash-face)
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>. (`Perl doc', `Regexp'): New submenus (latter to allow short displays). (cperl-clobber-lisp-bindings): New cfg variable. (cperl-find-pods-heres): $a->y() is not y///. (cperl-after-block-p): Add save-excursion. (cperl-init-faces): Was failing. Init faces when loading `ps-print'. (cperl-toggle-autohelp): New command. (cperl-electric-paren): `while SPACE LESS' was buggy. (cperl-init-faces): `-text' in `[-text => 1]' was not highlighted. (cperl-after-block-p): was FALSE after `sub f {}'. (cperl-electric-keyword): `foreachmy', `formy' expanded too, Expands `=pod-directive'. (cperl-linefeed): behaves reasonable in POD-directive lines. (cperl-message-electric-keyword): new cfg variable. (cperl-electric-keyword): print a message, governed by `cperl-message-electric-keyword'. (cperl-electric-paren): Typing `}' was not checking for being block or not. (cperl-beautify-regexp-piece): Did not know about lookbehind; finding *which* level to work with was not intuitive. (cperl-beautify-levels): New command. (cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command. (cperl-invert-if-unless): New command (C-c C-t and in Menu). (cperl-hints): mention 20.2's goods/bads. (cperl-extra-newline-before-brace-multiline): Started to use it. (cperl-break-one-line-blocks-when-indent): New cfg variable. (cperl-fix-hanging-brace-when-indent): New cfg variable. (cperl-merge-trailing-else): New cfg variable. Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric. (cperl-electric-keyword): Electric `do' inserts `do/while'. (cperl-fontify-syntaxically): New function. (cperl-syntaxify-by-font-lock): New cfg variable. Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated. (cperl-toggle-construct-fix): New command. Added on C-c C-w and menu. (auto-fill-mode): added on C-c C-f and menu. (cperl-style-alist): `PerlStyle' style added. (cperl-find-pods-heres): Message for termination of scan corrected. (cperl-speed): New variable with hints. (cperl-electric-else): Make backspace electric after expansion of `else/continue' too.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>. (`Perl doc', `Regexp'): New submenus (latter to allow short displays). (cperl-clobber-lisp-bindings): New cfg variable. (cperl-find-pods-heres): $a->y() is not y///. (cperl-after-block-p): Add save-excursion. (cperl-init-faces): Was failing. Init faces when loading `ps-print'. (cperl-toggle-autohelp): New command. (cperl-electric-paren): `while SPACE LESS' was buggy. (cperl-init-faces): `-text' in `[-text => 1]' was not highlighted. (cperl-after-block-p): was FALSE after `sub f {}'. (cperl-electric-keyword): `foreachmy', `formy' expanded too, Expands `=pod-directive'. (cperl-linefeed): behaves reasonable in POD-directive lines. (cperl-message-electric-keyword): new cfg variable. (cperl-electric-keyword): print a message, governed by `cperl-message-electric-keyword'. (cperl-electric-paren): Typing `}' was not checking for being block or not. (cperl-beautify-regexp-piece): Did not know about lookbehind; finding *which* level to work with was not intuitive. (cperl-beautify-levels): New command. (cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command. (cperl-invert-if-unless): New command (C-c C-t and in Menu). (cperl-hints): mention 20.2's goods/bads. (cperl-extra-newline-before-brace-multiline): Started to use it. (cperl-break-one-line-blocks-when-indent): New cfg variable. (cperl-fix-hanging-brace-when-indent): New cfg variable. (cperl-merge-trailing-else): New cfg variable. Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric. (cperl-electric-keyword): Electric `do' inserts `do/while'. (cperl-fontify-syntaxically): New function. (cperl-syntaxify-by-font-lock): New cfg variable. Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated. (cperl-toggle-construct-fix): New command. Added on C-c C-w and menu. (auto-fill-mode): added on C-c C-f and menu. (cperl-style-alist): `PerlStyle' style added. (cperl-find-pods-heres): Message for termination of scan corrected. (cperl-speed): New variable with hints. (cperl-electric-else): Make backspace electric after expansion of `else/continue' too. Fixed customization to honor cperl-hairy. Created customization groups. All the compile-time warnings fixed. (cperl-syntaxify-by-font-lock): Interaction with `font-lock-hot-pass' fixed. (cperl-after-block-and-statement-beg): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p, cperl-after-expr-p): Likewise. (cperl-indent-region): Make a marker for END - text added/removed. (cperl-style-alist): Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-tips, cperl-problems): Improvements to docs.

"Restore a style memorized by `cperl-set-style'."
(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>. (`Perl doc', `Regexp'): New submenus (latter to allow short displays). (cperl-clobber-lisp-bindings): New cfg variable. (cperl-find-pods-heres): $a->y() is not y///. (cperl-after-block-p): Add save-excursion. (cperl-init-faces): Was failing. Init faces when loading `ps-print'. (cperl-toggle-autohelp): New command. (cperl-electric-paren): `while SPACE LESS' was buggy. (cperl-init-faces): `-text' in `[-text => 1]' was not highlighted. (cperl-after-block-p): was FALSE after `sub f {}'. (cperl-electric-keyword): `foreachmy', `formy' expanded too, Expands `=pod-directive'. (cperl-linefeed): behaves reasonable in POD-directive lines. (cperl-message-electric-keyword): new cfg variable.

(cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command. (cperl-invert-if-unless): New command (C-c C-t and in Menu). (cperl-hints): mention 20.2's goods/bads. (cperl-extra-newline-before-brace-multiline): Started to use it. (cperl-break-one-line-blocks-when-indent): New cfg variable. (cperl-fix-hanging-brace-when-indent): New cfg variable. (cperl-merge-trailing-else): New cfg variable. Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric. (cperl-electric-keyword): Electric `do' inserts `do/while'. (cperl-fontify-syntaxically): New function. (cperl-syntaxify-by-font-lock): New cfg variable. Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated.

Merge changes from CPerl-5.0. (toplevel): Require man. (condition-case): Don't autoload tmm-prompt (it's in loaddefs.el). (cperl-electric-backspace-untabify): New var. (cperl-electric-backspace): Use it. (cperl-vc-header-alist): Extract numeric version from the Id. (cperl-build-manpage): New fun. (cperl-menu): Use it. Add toggle-autohelp. (cperl-mode) <defun-prompt_regexp>: Understand prototypes. (cperl-electric-brace): Use `cperl-after-block-p' for detection. (cperl-electric-keyword): Make $if (etc: "$@%&*") non-electric. '(' after keyword would insert a doubled paren. (cperl-calculate-indent): Update syntaxification before checks. Fix wrong indent of blocks starting with POD. (cperl-find-pods-heres): If no end of HERE-doc found, mark to the end of buffer. This enables recognition of end of HERE-doc "as one types". Require "\n" after trailing tag of HERE-doc. \( made non-quoting outside of string/comment (gdj-contributed). Likewise for \$. Remove `here-doc-group' text property at start (makes this property reliable). Text property `first-format-line' ==> t. Do not recognize $opt_s and $opt::s as s///. (cperl-after-block-p): Optional arg pre-block to check for a pre-block Recognize `continue' blocks too. (cperl-after-expr-p): Update syntaxification before checks. Work after here-docs, formats, and PODs too (affects many electric constructs). (cperl-fix-line-spacing): Allow "_" in $vars of foreach etc. (cperl-perldoc): Use case-sensitive search.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'.

(cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks.

Merge from upstream, upto version 5.22. After 5.0: `cperl-add-tags-recurse-noxs-fullpath': new function (for -batch mode) After 5.1: ;; Major edit. Summary of most visible changes: ;; a) Multiple <<HERE per line allowed. ;; b) Handles multiline subroutine declaration headers (with comments). ;; (The exception is `cperl-etags' - but it is not used in the rest ;; of the mode.) ;; c) Fontifies multiline my/our declarations (even with comments, ;; and with legacy `font-lock'). ;; d) Major speedup of syntaxification, both immediate and postponed ;; (3.5x to 15x [for different CPUs and versions of Emacs] on the ;; huge real-life document I tested). ;; e) New bindings, edits to imenu. ;; f) "_" is made into word-char during fontification/syntaxification; ;; some attempts to recognize non-word "_" during other operations too. ;; g) Detect bug in Emacs with `looking-at' inside `narrow' and bulk out. ;; h) autoload some more perldoc-related stuff ;; i) Some new convenience features: ISpell POD/HEREDOCs, narrow-to-HEREDOC ;; j) Attempt to incorporate XEmacs edits which reached me Fine-grained changelog: `cperl-hook-after-change': New configuration variable `cperl-vc-sccs-header': Likewise. `cperl-vc-sccs-header': Likewise. `cperl-vc-header-alist': Default via two preceding variables `cperl-invalid-face': Remove double quoting under XEmacs (still needed under 21.2) `cperl-tips': Update URLs for resources `cperl-problems': Likewise. `cperl-praise': Mention new features New C-c key bindings: for `cperl-find-bad-style', `cperl-pod-spell', `cperl-here-doc-spell', `cperl-narrow-to-here-doc', `cperl-perdoc', `cperl-perldoc-at-point' CPerl Mode menu changes: "Fix style by spaces", "Imenu on Perl Info" moved, new submenu of Tools with Ispell entries and narrowing. `cperl-after-sub-regexp': New defsubst `cperl-imenu--function-name-regexp-perl': Use `cperl-after-sub-regexp', Allows heads up to head4 Allow "package;" `defun-prompt-regexp': Use `cperl-after-sub-regexp', `paren-backwards-message': ???

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early.

(cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise.

(cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE.

(cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise.

(cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE.

$^L What formats output to perform a formfeed. Default is \\f.
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro.

(cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise.

Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx.

(cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early.

(cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'.

(cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx.

Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early.

(cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'.

(defun cperl-contract-levels ()
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>.

(cperl-electric-keyword): print a message, governed by `cperl-message-electric-keyword'. (cperl-electric-paren): Typing `}' was not checking for being block or not. (cperl-beautify-regexp-piece): Did not know about lookbehind; finding *which* level to work with was not intuitive. (cperl-beautify-levels): New command. (cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>. (`Perl doc', `Regexp'): New submenus (latter to allow short displays). (cperl-clobber-lisp-bindings): New cfg variable. (cperl-find-pods-heres): $a->y() is not y///.

(cperl-beautify-regexp-piece): Did not know about lookbehind; finding *which* level to work with was not intuitive. (cperl-beautify-levels): New command. (cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command. (cperl-invert-if-unless): New command (C-c C-t and in Menu). (cperl-hints): mention 20.2's goods/bads. (cperl-extra-newline-before-brace-multiline): Started to use it.

Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric. (cperl-electric-keyword): Electric `do' inserts `do/while'. (cperl-fontify-syntaxically): New function. (cperl-syntaxify-by-font-lock): New cfg variable. Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated. (cperl-toggle-construct-fix): New command. Added on C-c C-w and menu. (auto-fill-mode): added on C-c C-f and menu. (cperl-style-alist): `PerlStyle' style added.

"Change `if (A) {B}' into `B if A;' etc (or visa versa) if possible.
If the cursor is not on the leading keyword of the BLOCK flavor of
construct, will assume it is the STATEMENT flavor, so will try to find
the appropriate statement modifier."
(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>. (`Perl doc', `Regexp'): New submenus (latter to allow short displays). (cperl-clobber-lisp-bindings): New cfg variable. (cperl-find-pods-heres): $a->y() is not y///. (cperl-after-block-p): Add save-excursion. (cperl-init-faces): Was failing. Init faces when loading `ps-print'. (cperl-toggle-autohelp): New command. (cperl-electric-paren): `while SPACE LESS' was buggy. (cperl-init-faces): `-text' in `[-text => 1]' was not highlighted. (cperl-after-block-p): was FALSE after `sub f {}'. (cperl-electric-keyword): `foreachmy', `formy' expanded too, Expands `=pod-directive'. (cperl-linefeed): behaves reasonable in POD-directive lines. (cperl-message-electric-keyword): new cfg variable. (cperl-electric-keyword): print a message, governed by `cperl-message-electric-keyword'. (cperl-electric-paren): Typing `}' was not checking for being block or not. (cperl-beautify-regexp-piece): Did not know about lookbehind; finding *which* level to work with was not intuitive. (cperl-beautify-levels): New command. (cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command. (cperl-invert-if-unless): New command (C-c C-t and in Menu). (cperl-hints): mention 20.2's goods/bads. (cperl-extra-newline-before-brace-multiline): Started to use it.

(cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric. (cperl-electric-keyword): Electric `do' inserts `do/while'. (cperl-fontify-syntaxically): New function. (cperl-syntaxify-by-font-lock): New cfg variable. Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated. (cperl-toggle-construct-fix): New command. Added on C-c C-w and menu. (auto-fill-mode): added on C-c C-f and menu. (cperl-style-alist): `PerlStyle' style added.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>. (`Perl doc', `Regexp'): New submenus (latter to allow short displays). (cperl-clobber-lisp-bindings): New cfg variable. (cperl-find-pods-heres): $a->y() is not y///.

(cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command.

Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated. (cperl-toggle-construct-fix): New command. Added on C-c C-w and menu. (auto-fill-mode): added on C-c C-f and menu. (cperl-style-alist): `PerlStyle' style added.

Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>. (`Perl doc', `Regexp'): New submenus (latter to allow short displays). (cperl-clobber-lisp-bindings): New cfg variable. (cperl-find-pods-heres): $a->y() is not y///.

(cperl-electric-paren): `while SPACE LESS' was buggy. (cperl-init-faces): `-text' in `[-text => 1]' was not highlighted. (cperl-after-block-p): was FALSE after `sub f {}'. (cperl-electric-keyword): `foreachmy', `formy' expanded too, Expands `=pod-directive'. (cperl-linefeed): behaves reasonable in POD-directive lines. (cperl-message-electric-keyword): new cfg variable. (cperl-electric-keyword): print a message, governed by `cperl-message-electric-keyword'. (cperl-electric-paren): Typing `}' was not checking for being block or not. (cperl-beautify-regexp-piece): Did not know about lookbehind; finding *which* level to work with was not intuitive. (cperl-beautify-levels): New command. (cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command. (cperl-invert-if-unless): New command (C-c C-t and in Menu). (cperl-hints): mention 20.2's goods/bads. (cperl-extra-newline-before-brace-multiline): Started to use it.

Workaround for another `font-lock's `syntax-table' text-property bug. `zerop' could be applied to nil. At last, may work with `font-lock' without setting `cperl-font-lock'. (cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric. (cperl-electric-keyword): Electric `do' inserts `do/while'. (cperl-fontify-syntaxically): New function. (cperl-syntaxify-by-font-lock): New cfg variable. Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated. (cperl-toggle-construct-fix): New command. Added on C-c C-w and menu. (auto-fill-mode): added on C-c C-f and menu. (cperl-style-alist): `PerlStyle' style added.

(cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric.

(defun cperl-fontify-syntaxically (end)
Can use linear algorithm for indentation if Emacs supports it. (cperl-after-expr-p): It is BLOCK if we reach lim when backup sexp. (cperl-after-block-p): Likewise. (cperl-after-block-and-statement-beg): Likewise. (cperl-after-block-p): After END/BEGIN we are a block. (cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx. (cperl-syntaxify-by-font-lock): Set to t, should be safe now. Better default, customizes to `message' too, off in text-mode. (cperl-array-face): Renamed from `font-lock-emphasized-face', `defface'd. (cperl-hash-face): Renamed from `font-lock-other-emphasized-face'. `defface'd. (cperl-emacs-can-parse): New state variable. (cperl-indent-line): Corrected to use global state. (cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements.

Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position.

Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>. (`Perl doc', `Regexp'): New submenus (latter to allow short displays). (cperl-clobber-lisp-bindings): New cfg variable. (cperl-find-pods-heres): $a->y() is not y///. (cperl-after-block-p): Add save-excursion. (cperl-init-faces): Was failing. Init faces when loading `ps-print'. (cperl-toggle-autohelp): New command. (cperl-electric-paren): `while SPACE LESS' was buggy. (cperl-init-faces): `-text' in `[-text => 1]' was not highlighted. (cperl-after-block-p): was FALSE after `sub f {}'.

(cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'. Should preserve `syntax-table' properties even with `lazy-lock'. (cperl-indent-region-fix-else): New command. (cperl-fix-line-spacing): New command.

(cperl-indent-region-fix-constructs): Renamed from `cperl-indent-region-fix-constructs'. (cperl-fix-line-spacing): could be triggered inside strings, would not know what to do with BLOCKs of map/printf/etc. (cperl-merge-trailing-else): Handle `continue' too. (cperl-fix-line-spacing): Likewise. (cperl-calculate-indent): Knows about map/printf/etc before {BLOCK}; treat after-comma lines as continuation lines. (cperl-mode): `continue' made electric.

Make syntaxification to be autoredone via `font-lock', switched on by `cperl-syntaxify-by-font-lock', off by default so far. Remove some commented out chunks. (cperl-set-style-back): Old value of style is memorized when choosing a new style, may be restored from the same menu. Mode-documentation added to micro-docs. (cperl-praise): updated. (cperl-toggle-construct-fix): New command. Added on C-c C-w and menu. (auto-fill-mode): added on C-c C-f and menu. (cperl-style-alist): `PerlStyle' style added.

(cperl-style-alist): New variable, since `c-mode' is no longer loaded. - (Somebody who uses the styles should check that they work OK!) - (a lot of work is needed, especially with new `cperl-fix-line-spacing'). Old value of style is memorized when choosing a new style, may be restored from the same menu. (cperl-perldoc, cperl-pod-to-manpage): New commands; thanks to Anthony Foiani <afoiani@uswest.com> and Nick Roberts <Nick.Roberts@src.bae.co.uk>.

(cperl-electric-keyword): print a message, governed by `cperl-message-electric-keyword'. (cperl-electric-paren): Typing `}' was not checking for being block or not. (cperl-beautify-regexp-piece): Did not know about lookbehind; finding *which* level to work with was not intuitive. (cperl-beautify-levels): New command. (cperl-electric-keyword): Allow here-docs contain `=head1' and friends for keyword expansion. Fix for broken `font-lock-unfontify-region-function'.

(cperl-after-expr-p): Skip labels when checking (cperl-indent-region): Make a marker for END - text added/removed. Disable hooks during the call (how to call them later?). Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise. (cperl-problems): Improvements to docs. (cperl-tips): Likewise. (cperl-non-problems): Likewise. (cperl-mode): Make lazy syntaxification possible. Loads pseudo-faces for the sake of `cperl-find-pods-heres' (for 19.30). `font-lock-unfontify-region-function' was set to a wrong function. (cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine. Was treating $a++ <= 5 as a glob. Tolerate unfinished REx at end-of-buffer. `unwind-protect' was left commented. / and ? after : start a REx.

(cperl-calculate-indent): Likewise. (cperl-fix-line-spacing): Likewise (not used yet). (cperl-calculate-indent): Did not consider `,' as continuation mark for statements. (cperl-calculate-indent): Avoid parse-data optimization at toplevel. Remove another parse-data optimization at toplevel: would indent correctly. Correct for labels when calculating indentation of continuations. Docstring updated. (cperl-choose-color): Converted to a function (to be compilable in text-mode). (cperl-dark-background): Disable without window-system. Do `defface' only if window-system. (cperl-fix-line-spacing): sped up to bail out early. (x-color-defined-p): was not compiling on XEmacs Was defmacro'ed with a tick. Remove another def. (cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro.

Now indents 820-line-long function in 6.5 sec (including syntaxification) the first time (when buffer has few properties), 7.1 sec the second time. (cperl-indent-region): Do not indent whitespace lines (cperl-style-alist) Include `cperl-merge-trailing-else' where the value is clear. (cperl-styles-entries): Likewise.

(cperl-find-pods-heres): Safe a position in buffer where it is safe to restart syntaxification. Changed so that -d ?foo? is a RE. Do not warn on `=cut' if doing a chunk only. 1 << 6 was OK, but 1<<6 was considered as HERE-doc. <file/glob> made into a string. Postpone addition of faces after syntactic step. Recognition of <FH> was wrong. Highlight `gem' in s///gem as a keyword. `qr' recognized. Knows that split// is null-RE. Highlights separators in 3-parts expressions as labels. <> was considered as a glob. Would err if the last line is `=head1'. $a-1 ? foo : bar; was a considered a regexp. `<< (' was considered a start of HERE-doc. mark qq[]-etc sections as syntax-type=string Was not processing sub protos after a comment ine.

(cperl-clobber-lisp-bindings): if set, C-c variants are the old ones (cperl-unwind-to-safe): New function. (cperl-fontify-syntaxically): Use `cperl-unwind-to-safe' to start at reasonable position. (cperl-fontify-syntaxically): Unwinds start and end to go out of long strings (not very successful). (cperl-forward-re): Highlight the trailing / in s/foo// as string. Highlight the starting // in s//foo/ as function-name. Emit a meaningful error instead of a cryptic one for an uncomplete REx near end-of-buffer. (cperl-electric-keyword): `qr' recognized. (cperl-electric-else): Likewise (cperl-to-comment-or-eol): Likewise (cperl-make-regexp-x): Likewise (cperl-init-faces): Likewise, and `lock' (as overridable?). Corrected to use new macros; `if' for copying `reference-face' to `constant-face' was backward. remove init `font-lock-other-emphasized-face', `font-lock-emphasized-face', `font-lock-keyword-face'. Interpolate `cperl-invalid-face'. (cperl-make-regexp-x): Misprint in a message. (cperl-syntaxify-unwind): New configuration variable (cperl-fontify-m-as-s): New configuration variable (cperl-electric-pod): check for after-expr was performed inside of POD too. (cperl-backward-to-noncomment): better treatment of PODs and HEREs. (cperl-clobber-mode-lists): New configuration variable. (cperl-not-bad-style-regexp): Updated. Init: `cperl-is-face' was busted. (cperl-make-face): New macros. (cperl-force-face): New macros. (font-lock-other-type-face): Done via `defface' too. (cperl-nonoverridable-face): New face. Renamed from `font-lock-other-type-face'. (cperl-init-faces-weak): use `cperl-force-face'. (cperl-comment-indent): Commenting __END__ was not working. (cperl-indent-for-comment): Likewise. (cperl-write-tags): Correct for XEmacs's `visit-tags-table-buffer'. When removing old TAGS info was not relativizing filename. (cperl-tags-hier-init): Gross hack to pretend we work (are we?). Another try to work around XEmacs problems. Better progress messages. (toplevel): require custom unprotected => failure on 19.28. (cperl-xemacs-p): defined when compile too (cperl-find-tags): Was writing line/pos in a wrong order, pos off by 1 and not at beg-of-line. (cperl-etags-snarf-tag): New macro (cperl-etags-goto-tag-location): New macro (cperl-version): New variable. New menu entry random docstrings: References to "future" 20.3 removed. Menu was described as `CPerl' instead of `Perl' (perl-font-lock-keywords): Would not highlight `sub foo($$);'. (cperl-toggle-construct-fix): Was toggling to t instead of 1. (cperl-ps-print-init): Associate `cperl-array-face', `cperl-hash-face' Remove `font-lock-emphasized-face', `font-lock-other-emphasized-face', `font-lock-reference-face', `font-lock-keyword-face'. Use `eval-after-load'. Remove not-CPerl-related faces. (cperl-tips-faces): New variable and an entry into Mini-docs. (cperl-indent-exp): Was not processing else-blocks. (cperl-get-state): NOP line removed. (cperl-ps-print): New function and menu entry. (cperl-ps-print-face-properties): New configuration variable. (cperl-invalid-face): New configuration variable. (perl-font-lock-keywords): Highlight trailing whitespace (cperl-contract-levels): Documentation corrected. (cperl-contract-level): Likewise. (cperl-ps-extend-face-list): New macro. (cperl-invalid-face): Change to ''underline.
