* lisp/cedet/semantic/symref/grep.el (semantic-symref-grep--local-dir):
New variable.
(semantic-symref-perform-search): Use it. And use "." when
expanding the template to substitute for the current dir.
(semantic-symref-parse-tool-output-one-line): Use it (bug#55016)
`xref-find-references` was unable to find symbols like
`backquote-list*-macro`.
* lisp/cedet/semantic/symref/grep.el
(semantic-symref-grep--quote-extended): New function.
(semantic-symref-perform-search): Call it.
* lisp/cedet/semantic/symref/grep.el (semantic-symref-perform-search):
Use the `-w` flag instead of wrapping the pattern in regexps that make
matching much slower. This speeds up `xref-find-references` by about
3× on macOS.
* lisp/progmodes/grep.el (grep-compute-defaults):
Add '-H' to grep-find-template (bug#48471).
* lisp/cedet/semantic/symref/grep.el (semantic-symref-perform-search):
Pass the root directory name without the trailing slash.
* lisp/progmodes/xref.el (xref-matches-in-directory): Ditto.
* test/lisp/progmodes/xref-tests.el (xref--xref-file-name-display-is-abs)
(xref--xref-file-name-display-is-relative-to-project-root):
Make tests more strict again.
* lisp/progmodes/project.el (project--files-in-directory):
Make sure the directory includes the trailing slash in case it's
a symlink, discussed in
https://lists.gnu.org/archive/html/emacs-devel/2021-01/msg00345.html.
* lisp/progmodes/xref.el (xref-matches-in-directory): Same.
* lisp/cedet/semantic/symref/grep.el (semantic-symref-perform-search):
Same.
* lisp/cedet/semantic/symref/grep.el
(semantic-symref-filepattern-alist): Fix the entry for
'html-mode', which used a regexp-like syntax where only glob
syntax is permitted. As a result, 'xref-find-references' (M-?)
can now find references in HTML files. Also duplicate the same
entry for the sake of 'mhtml-mode', and add a new one for
'python-mode'.
(semantic-symref-derive-find-filepatterns): In the documentation,
clarify that returned patterns must follow the glob syntax. Fix
an 'if' test that always evaluates to nil.
(semantic-symref-tool-grep):
(semantic-symref-perform-search): Fix typos.
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.
* lisp/cedet/semantic/symref/grep.el (greppattern): Remove.
(grepflags): Rename to semantic-symref-grep-flags.
(semantic-symref-grep-expand-keywords): Update accordingly.
(semantic-symref-grep-use-template): Remove the last two
arguments to make sure they don't shadow the (not renamed)
global variables.
(semantic-symref-perform-search)
(semantic-symref-parse-tool-output-one-line): Use slot names
instead of keywords, like the byte-compiler wants us to.
* lisp/progmodes/grep.el (grep-mode-font-lock-keywords): Allow for NUL
characters following filename in grep context lines.
(grep--regexp-alist-column, grep--regexp-alist-bin-matcher)
(grep-with-null-regexp-alist, grep-fallback-regexp-alist): Remove.
(grep-regexp-alist): Recombine their contents here.
(grep-mode):
* lisp/cedet/semantic/symref/grep.el
(semantic-symref-parse-tool-output-one-line):
* lisp/progmodes/xref.el (xref-collect-matches): Use the variable
`grep-regexp-alist' rather than the function.
* lisp/cedet/semantic/symref/grep.el
(semantic-symref-grep--line-re): Delete.
(semantic-symref-parse-tool-output-one-line):
Use regexp and group numbers from (grep-regexp-alist).
* lisp/progmodes/xref.el (xref-collect-references): Instead of
calling `semantic-symref-find-references-by-name', use
`semantic-symref-instantiate' and `semantic-symref-perform-search'
directly. Ask for `line-and-text' results (bug#23223).
(xref-collect-matches): Include the line text in the "hit"
structure.
(xref--convert-hits): New function, split off from
`xref-collect-references' and `xref-collect-matches', to convert
"hits" to xref instance list. Create a temporary buffer here, to
use it for post-processing all hit lines.
(xref--collect-matches): Use a different approach for non-visited
files. Insert the line text into the temp buffer, apply the
file's major mode the best we can without reading its whole
contents, syntax-propertize, and search in the result.
(xref--collect-matches-1): Extract, to handle the common logic
between two cases.
(xref--find-buffer-visiting): New function, a wrapper around
`find-buffer-visiting' to amortize its cost.
* lisp/cedet/semantic/symref/idutils.el
(semantic-symref-idutils--line-re): New constant.
(semantic-symref-parse-tool-output-one-line): Support result type
`line-and-text'.
* lisp/cedet/semantic/symref/grep.el
(semantic-symref-grep--line-re)
(semantic-symref-parse-tool-output-one-line): Same.
* lisp/cedet/semantic/symref/cscope.el
(semantic-symref-cscope--line-re)
(semantic-symref-parse-tool-output-one-line): Same.
* lisp/cedet/semantic/symref/global.el
(semantic-symref-global--line-re)
(semantic-symref-parse-tool-output-one-line): Same.
* lisp/cedet/semantic/symref/grep.el
(semantic-symref-derive-find-filepatterns): Return a list.
(semantic-symref-perform-search): Quote the result here once and for all.
* lisp/cedet/semantic/symref/grep.el
(semantic-symref-derive-find-filepatterns): Use
'shell-quote-argument' instead of manually quoting in a way that
only works with Posix shells. (Bug#22289)
* lisp/cedet/semantic/symref/grep.el
(semantic-symref-grep-use-template): Update a comment.
* lisp/progmodes/grep.el (grep-compute-defaults): Restore <D>
instead of '.' in grep-find-template (bug#20719).
(rgrep): Pass nil as the directory to rgrep-default-command.
* lisp/progmodes/grep.el (grep-expand-keywords): Use '.' as the
default value for DIR.
* lisp/progmodes/xref.el (xref-collect-matches): Drop the
workaround.
* lisp/cedet/semantic/symref/grep.el
(semantic-symref-perform-search): Instead of wrapping input in
word boundaries, check that the characters before and after are
not word constituents.
* lisp/cedet/semantic/symref.el
(semantic-symref-hit-to-tag-via-buffer): Don't regexp-quote when
the search type is regexp.
* lisp/cedet/semantic/symref/grep.el
(semantic-symref-perform-search): Support the regexp search type.
Pass -E to Grep when it's used.
* lisp/cedet/semantic/symref/idutils.el
(semantic-symref-parse-tool-output-one-line): Fix the search
regexp to match MS-Windows file names with drive letters.
(Bug#19468)
* lisp/cedet/semantic/symref/grep.el
(semantic-symref-grep-use-template): Remove "--color=always" from
Grep switches on MS-Windows.
(semantic-symref-grep-shell): Use shell-file-name as the default
value, so this works not only on Posix platforms.
(semantic-symref-perform-search): Use shell-quote-argument instead
of literal '..' for portable quoting of Grep command-line
argument. Use shell-command-switch instead of a literal "-c".
* lisp/cedet/semantic/bovine/gcc.el
(semantic-gcc-get-include-paths): Use file-name-absolute-p to test
for an absolute file name in a portable way.
