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.
In particular, multiline comments lacking escaped newlines.
* lisp/progmodes/cc-engine.el (c-backward-sws): Whilst searching backward for
a putative beginning of macro, move back over block comments whose innards
lack escaped newlines.
* lisp/progmodes/cc-langs.el (c-last-open-c-comment-start-on-line-re): Comment
out.
(c-open-c-comment-on-logical-line-re): Remove.
* lisp/progmodes/cc-engine.el (c-end-of-macro): Handle multiline block
comments lacking escaped newlines using parse-partial-sexp rather than the
former variables removed from cc-langs.el.
* lisp/sort.el (reverse-region): Signal a user-error if the region
includes less than one full line, thus avoiding an inadvertent
deletion of text following the current line. Fix the doc string.
Fix comments to start with a capital letter. (Bug#39376)
* lisp/emacs-lisp/package.el (package-menu-mode-menu): Remove obsolete
menu entry "Redisplay buffer".
(package-menu-mode-menu): Menu entry "Refresh Package List":
make the doc string more accurate.
(Bug#39436)
When the 'msft' rule was moved and modified, the old copy was left
in place by mistake.
* lisp/progmodes/compile.el (compilation-error-regexp-alist-alist):
Remove old rule.
This argument was added for the 'or' clause in rx, but it turned out
to be a bad idea (bug#37659), and there seems to be little other use
for it.
* lisp/emacs-lisp/regexp-opt.el (regexp-opt): Remove KEEP-ORDER.
* doc/lispref/searching.texi (Regexp Functions):
* etc/NEWS: Remove it from the documentation.
* test/lisp/emacs-lisp/regexp-opt-tests.el (regexp-opt-test--match-all)
(regexp-opt-test--check-perm, regexp-opt-test--explain-perm)
(regexp-opt-keep-order, regexp-opt-longest-match): Simplify test.
* lisp/minibuffer.el (minibuffer--message-overlay-pos): New
function.
(set-minibuffer-message): Use it to determine where to show the
overlay with the temporary message.
* lisp/ido.el (ido-exhibit): Revert "Render Ido suggestions using
an overlay"; this restores the original code which inserted the
match-status information into the minibuffer, instead of
displaying it in an overlay with an after-string. Put the special
'minibuffer-message' text property at the beginning of the
inserted text. (Bug#39379)
* etc/NEWS:
* doc/lispref/display.texi (Displaying Messages):
* doc/lispref/text.texi (Special Properties): Document the
'minibuffer-message' text property and its effect.
Revert to the Emacs 26 semantics that always gave the longest match
for rx 'or' forms with only string arguments. This guarantee was
never well documented, but it is useful and people likely have come to
rely on it. For example, prior to this change,
(rx (or ">" ">="))
matched ">" even if the text contained ">=".
* lisp/emacs-lisp/rx.el (rx--translate-or): Don't tell regexp-opt to
preserve the matching order.
* doc/lispref/searching.texi (Rx Constructs): Document the
longest-match guarantee for all-string 'or' forms.
* test/lisp/emacs-lisp/rx-tests.el (rx-or): Update test.
* lisp/vc/vc-hg.el (vc-hg-dir-status-files):
Make sure it works correctly in a subdirectory of the repo root.
Bind default-directory to DIR and add 're: -I .' to the arguments
(bug#39380).
* lisp/progmodes/cc-langs.el (c-last-open-c-comment-start-on-line-re): Make
obsolete, and supersede by ...
(c-open-c-comment-on-logical-line-re): New language variable.
* lisp/progmodes/cc-engine.el (c-end-of-macro): Inside macros, handle
multiline block comments whose line ends are not escaped correctly.
* doc/emacs/package.texi (Package Menu): Improve the description
of the 'H' command.
* lisp/emacs-lisp/package.el (package-menu-mode-menu): More
accurate wording of the help-echo string.
(package-menu-hide-package): Make the doc string more accurate.
(Bug#39436)
That commit caused errors when the connection was dropped in the
middle of a package refresh. To avoid any further issues this close
to the pretest, we simply remove this feature. (Bug#39187)
Don't merge to master, where we will instead try to fix the bug.
* lisp/gnus/mm-view.el (mm-display-inline-fontify):
* lisp/vc/diff-mode.el (diff-syntax-fontify-props):
* lisp/vc/vc.el (vc-find-revision-no-save):
Add delay-mode-hooks around set-auto-mode calls
to not run hooks that might assume buffer-file-name
really associates buffer with a file.
Fixes Bug#39363.
* configure.ac: Add check for 3-argument version of
pthread_setname_np.
* src/systhread.c (sys_thread_set_name)
[HAVE_PTHREAD_SETNAME_NP_3ARG]: Call pthread_setname_np with
3 arguments.
* lisp/subr.el (add-to-ordered-list, add-to-history):
* doc/lispref/lists.texi (List Variables):
* doc/lispref/minibuf.texi (Minibuffer History):
Note in the doc string and manual that the variable arguments to
add-to-ordered-list and add-to-history cannot refer to a lexical
variable (bug#39373).
Since 'add-to-list', being a plain function, cannot access lexical
variables, such use must be rewritten for correctness.
(Some instances actually do work thanks to a compiler macro,
but it's not something code should rely on.)
* lisp/autoinsert.el (auto-insert-alist):
* lisp/cedet/mode-local.el (mode-local-print-bindings):
* lisp/net/tramp-cache.el (tramp-flush-connection-properties)
(tramp-list-connections):
* lisp/net/zeroconf.el (zeroconf-list-service-names)
(zeroconf-list-service-types, zeroconf-list-services):
* lisp/org/org.el (org-reload):
* lisp/whitespace.el (whitespace-report-region):
* test/lisp/emacs-lisp/map-tests.el (test-map-do):
Replace add-to-list with push.
While add-to-list often works with lexical variables, this is a hack
that isn't always effective; better tell the user not to try.
* doc/lispref/lists.texi (List Variables): Add a note about lexical
variables to the add-to-list description. Fix the equivalent code.
* lisp/subr.el (add-to-list): Amend doc string.
* lisp/mh-e/mh-show.el (mh-display-msg, mh-show-mode): buffer-altering
code formerly in mh-show-mode is moved to the location in mh-display-msg
where mh-show-mode used to be called before the fix to MH-E bug #470
moved the call earlier.
* lisp/mh-e/mh-e.el, doc/misc/mh-e.texi (mh-show-mode-hook): Now that
the fix for MH-E bug #470 calls mh-show-mode-hook earlier, update the
documentation to no longer say that the message contents are available.
* lisp/net/goto-addr.el, doc/emacs/misc.texi: Do not use MH-E as the
example of how to add a hook to goto-address, because MH-E calls
goto-address internally.
This patch adds all capital blackboard bold letters and those for "1"
and "2". Most characters are in common use in mathematics, but it does
not seem useful to exclude the few not widely used.
Reference: https://en.wikipedia.org/wiki/Blackboard_bold
* lisp/leim/quail/latin-ltx.el (latin-ltx--define-rules): Add all
the blackboard bold commands from AMSTeX. (Bug#21103)
