compiled changes but don't include a file name each error message.
Speed up by searching for regexps one by one instead of combining.
(compile-internal): Takes more optional arguments. All five regexp
alists can be given as argument.
Change name of variable regexp-alist to error-regexp-alist. Change
some local variables directly by setq instead of rebinding by let.
(compilation-shell-minor-mode): New minor mode.
Similar to compilation-minor-mode, but key bindings don't
collide with shell mode.
(compilation-shell-minor-mode-map, compilation-shell-minor-mode):
New variables.
(compile-auto-highlight): Doc fix.
(compilation-error-regexp-alist): Removed unnecessary line break
in first regexp. Replaced \\(\\|.* on \\) by \\(.* on \\)? in
regexp for Absoft FORTRAN 77 Compiler 3.1.3. Added regexp for
SPARCcompiler Pascal. Divided long line in regexp for Cray C
compiler error messages. Made comment fit in line at regexp for
Sun Ada (VADS, Solaris). FILE-IDX may be nil, meaning an
error message with no file name, so the file name must be taken
from an earlier message. LINE-IDX may be a function which is
called with two arguments the file name and column strings and
returns an error position descriptor.
(compilation-enter-directory-regexp-alist)
(compilation-leave-directory-regexp-alist): New variables.
(compilation-file-regexp-alist)
(compilation-nomessage-regexp-alist): New variables.
(grep-regexp-alist): Removed unnecessary ^ at beginning of regexp.
(compilation-enter-directory-regexp)
(compilation-leave-directory-regexp): Variables deleted.
Replaced by compilation-enter-directory-regexp-alist and
compilation-leave-directory-regexp-alist.
(compilation-buffer-p): Return true also for buffer in
compilation-shell-minor-mode.
(compilation-next-error-locus): Split a long line.
(count-regexp-groupings): Comment about this function not being
needed any more.
(compilation-current-file, compilation-regexps); New variables.
(compilation-parse-errors): Large parts rewritten. Don't put the
regexps together in one large regexp, instead match them one by one.
Support the generalized subexpression indices.
(compile-collect-regexps, compile-buffer-substring): New functions
supporting compilation-parse-errors.
(grep-command): Use it, and test whether it supports the -e
option; fix doc string (last command is stored in history variable).
(grep-null-device): Declare before grep-program and grep-command.
(grep-find-use-xargs, grep-find-command, grep-find-history):
New variables.
(grep-find): New command.
(grep): Only concatenate grep-null-device to COMMAND when it's
not nil (to support grep-find).
(compilation-handle-exit): Parse error messages here
as specified by compile-highlight-display-limit.
(compile-reinitialize-errors): Add highlighting to error messages
once they are parsed.
(compilation-forget-errors): Remove highlighting properties here.
(compilation-sentinel, compile-internal): Use it.
(compilation-exit-message-function): Doc fix for protocol change: take
process status and exit-code args instead of process object.
(grep): Use new protocol for compilation-exit-message-function.
processes: do relevant parts of compilation-sentinel after the
process exits; make modeline during and after compilation be
similar to what compilation-sentinel displays.
(compilation-sentinel): If compilation-exit-message-function is non-nil,
call it to produce messages for buffer and mode line.
(grep): Use that variable to produce snazzier messages.
abbreviate-file-name to it and then use its directory part as the first
search path element, searching for its nondirectory part.
Fix prompting code not to use a free variable.
(compilation-parse-errors, compile-abbreviate-directory): Use
abbreviate-file-name on directories.
(compilation-parse-errors): Don't store the beginning of the line
containing the end of the error-regexp match. Instead, store the beginning
of the line containing the start of the match, unless the match starts
with a newline, in which case the beginning of the next line.
