Perform 'regexp-opt' on nested 'or' forms, and after expansion of
user-defined and 'eval' forms. Characters are now turned into strings
for wider 'regexp-opt' scope. This preserves the longest-match
semantics for string in 'or' forms over composition.
* doc/lispref/searching.texi (Rx Constructs): Document.
* lisp/emacs-lisp/rx.el (rx--normalise-or-arg)
(rx--all-string-or-args): New.
(rx--translate-or): Normalise arguments first, and check for strings
in subforms.
(rx--expand-eval): Extracted from rx--translate-eval.
(rx--translate-eval): Call rx--expand-eval.
* test/lisp/emacs-lisp/rx-tests.el (rx-or, rx-def-in-or): Add tests.
* etc/NEWS: Announce.
Distinguish offsets between manual-vs-automatic scrolling
as integers-vs-floats instead of positive-vs-negative integers.
* lisp/tab-line.el (tab-line-format-template): Use 'numberp'
instead of 'integerp', and 'truncate' instead of 'abs'.
(tab-line-format): When the window-buffer was updated, set window-parameter
to float to enable auto-hscroll after it was disabled on manual scrolling.
(tab-line-auto-hscroll-buffer): New variable with internal buffer.
(tab-line-auto-hscroll): Erase in tab-line-auto-hscroll-buffer.
Use 'numberp' instead of 'integerp', 'truncate' instead of 'abs',
and 'float' instead of '-'.
(tab-line-hscroll): Use 'numberp' instead of 'integerp',
and 'truncate' instead of 'abs'.
This prevents a crash when attempting to create a zero-width bitmap.
* src/fringe.c (Fdefine_fringe_bitmap): Check value of width,
signal an error if outside documented range (Bug#39662).
* src/gnutls.c (syms_of_gnutls) <libgnutls-version>: Define with
DEFVAR_LISP and add docstring, so that this variable will accessible by
help facilities.
without an intervening call to after-change-functions. This would have been a
workaround to bug #38691 had the causes of that bug not been removed.
* lisp/progmodes/cc-mode.el (c-just-done-before-change): Add an extra value to
this variable, 'whole-buffer, this being set by c-before-change as a signal to
c-after-change that although c-before-change has run, it has assumed the
entire buffer as the change region.
(c-before-change, c-after-change): Adapt to the new meaning of the above.
* lisp/progmodes/cc-engine.el (c-forward-decl-or-cast-1): While attempting to
find a declaration's identifier, recast the latest found id. as that
identifier when there is no other type identifier and the result of the most
recent c-forward-type call is 'maybe or 'found. In the latter case, remove
the id. from the found types list, too.
* lisp/vc/vc-dir.el (vc-dir-ignore):
Pass relative file names to vc-ignore.
* lisp/vc/vc.el (vc-ignore): Move the responsibility of
constructing the ignore pattern (right now, most often a relative
file name) using a file name received from the user, here.
(vc-default-ignore): ...from here (bug#37189, see discussion).
Also clarify the docstring.
* doc/lispref/searching.texi (Char Classes): Warn about erroneous
usage of named character classes. Suggested by Stephen Leake
<stephen_leake@stephe-leake.org>.
* lisp/vc/vc-cvs.el (vc-cvs-ignore): Expand filename correctly
and pass on only the basename as the pattern.
(vc-cvs-append-to-ignore) Do not write duplicate strings to
.cvsignore. New optional parameter SORT to more explicitly
control sorting of the ignore entries. (Bug#37215)
* lisp/vc/pcvs.el (cvs-mode-ignore): Call 'vc-cvs-append-to-ignore'
with SORT argument.
Most of the manual here addresses Message mode, yet talks about
'send-mail-function' which is used for Mail mode.
Fixing this completely requires more involved work, but for now at
least document the difference here.
* doc/emacs/sending.texi (Mail Sending): Mention
'message-send-mail-function'. (Bug#39639)
Most of the manual here addresses Message mode, and C-c C-c directly
above cites the Message mode command, not the Mail mode command.
* doc/emacs/sending.texi (Mail Sending): Fix reference. (Bug#39639)
When the eshell prompt is protected (e.g., with rear non-sticky,
inhibited movements, etc.), 'beginning-of-line' won't move to the
actual beginning of the line and therefore won't skip over the
prompt.
* lisp/eshell/em-prompt.el (eshell-previous-prompt): Use
'forward-line' to go to the beginning of the line, even if it's
protected. (Bug#39627)
Incorrect escaping prevented these from working as intended.
Found by relint.
* lisp/progmodes/cc-defs.el (c-search-backward-char-property):
Add missing backslash.
* lisp/progmodes/simula.el (simula-mode):
Remove one backslash too many.
Problem reported by Ken Sasaki (Bug#39672).
* src/fileio.c (Ffile_directory_p):
Encode filename before giving it to file_directory_p.
This fixes a typo introduced in
2019-09-18T02:18:14Z!eggert@cs.ucla.edu.
When run with -p or -P, OMake regurgitates error messages that
prevented further progress, indented by 6 spaces. Use that fact
to ameliorate the modification done to other error message regexps.
* lisp/progmodes/compile.el (compilation-parse-errors):
When 'omake' is enabled, allow error messages to be indented by 0 or 6
spaces instead of any number of spaces, to avoid pathological
behaviour.
(compilation-error-regexp-alist-alist): Anchor the 'omake' pattern to
bol for performance. Repair the 'ruby-Test::Unit' pattern, which
relied on the previously over-generous 'omake' hack.
* etc/compilation.txt (OMake): Add examples.
* test/lisp/progmodes/compile-tests.el (compile-tests--test-regexps-data)
(compile-test-error-regexps): Add test for OMake (indented error).
They have similar structure, and both suffer from being able to
match leading spaces in multiple ways which leads to bad performance
when backtracking (bug#39595).
* lisp/progmodes/compile.el (compilation-error-regexp-alist-alist):
Improved 'msft' and 'watcom' regexps.
Anchor the regexp at line-start to prevent quadratic behaviour when
it doesn't match (bug#39595). It's unclear whether the type tag, like
[ERROR], is always present; we keep it optional just in case.
* lisp/progmodes/compile.el (compilation-error-regexp-alist-alist):
Rewrite 'maven' regexp, using rx for clarity.
* etc/compilation.txt (maven): More examples.
* test/lisp/progmodes/compile-tests.el
(compile-tests--test-regexps-data): No leading spaces; they seems to
stem from a misunderstanding in bug#11517.
