* lisp/emacs-lisp/bytecomp.el (byte-compile-file): Bind
`byte-compiler-error-flag' instead of setting it (bug#41065).
This fixes a problem of "leaking" the flag when compiling
something that then compiles something that errors out (i.e., an
"inner" compile).
* lisp/progmodes/tcl.el (tcl-syntax-propertize-function):
Propertize {} forms after commands as strings (bug#39277).
(tcl-set-font-lock-keywords): Fontify as strings. This allows
things like puts {"foo} to be fontified correctly.
Copyright-paperwork-exempt: yes
* lisp/help-mode.el (help-mode-revert-buffer): Don't require
confirmation before reverting (bug#44202). This mimics how most
other non-file reverting functions work.
* lisp/mh-e/mh-show.el (mh-display-msg):
* lisp/textmodes/rst.el: Don't use obsolete variable
write-contents-hooks.
Problem reported by Stefan Monnier <monnier@iro.umontreal.ca>.
* lisp/mail/hashcash.el (hashcash-point-at-bol)
(hashcash-point-at-eol): Make obsolete.
(hashcash-token-substring): Don't use the above now obsolete aliases.
* lisp/vc/vc.el (vc-responsible-backend): Search through all the
VC backends instead of the first one, and choose the one that's
most specific (bug#42966).
* doc/lispref/modes.texi (Defining Minor Modes): Describe the new
:predicate keyword (bug#44232).
* lisp/emacs-lisp/easy-mmode.el (define-globalized-minor-mode):
Allow a new :predicate keyword.
(easy-mmode--globalized-predicate-p): New function.
* lisp/emacs-lisp/shortdoc.el (shortdoc-example): Removed.
(shortdoc-section): Remove colors.
(shortdoc-separator): New face.
(shortdoc-display-group, shortdoc--display-function): Don't use
background colours, because that makes things harder to read.
Separate with a horizontal line instead.
* src/composite.c (composition_gstring_cache_clear_font): New
function.
* src/composite.h (composition_gstring_cache_clear_font): Add
prototype.
* src/font.c (font_clear_cache): When we are about to close a
font, remove from the gstring cache any lgstring that uses this
font. (Bug#42943)
While there are currently no known security holes in play-sound-file,
the attack surface is considerable and historically audio file
processing has had more than its share of security problems; the
benefit to risk ratio is low.
* lisp/emacs-lisp/unsafep.el: Don't mark play-sound-file as safe.
* src/composite.c (composition_gstring_lookup_cache): Renamed from
gstring_lookup_cache and made external. All callers changed.
* src/composite.h (composition_gstring_lookup_cache): Add
prototype.
* src/font.c (Ffont_shape_gstring): Call
composition_gstring_lookup_cache and return the cached composition
if it is already in the cache.
* lisp/language/misc-lang.el (egyptian-shape-grouping): New
function.
(composition-function-table): Use egyptian-shape-grouping in
setting up compositions for Egyptian Hieroglyphs. Fix the
composition setup for horizontal and vertical joiners.
* lisp/emacs-lisp/checkdoc.el (checkdoc-autofix-ask-replace):
Ensure that the end-of-doc-string marker is really at the end,
even if we replace the final " char in the string (bug#44201).
XRef supports Emacs versions back to Emacs 26.3, so it can’t use newer
functions such as ‘ert-resource-directory’.
* test/lisp/progmodes/xref-tests.el (xref-tests-data-dir): Don’t use
‘ert-resource-directory’
Flymake supports all Emacs versions back to 26.1, so it can’t use
‘ert-resource-file’.
* test/lisp/progmodes/flymake-tests.el (flymake-tests-data-directory):
Recreate.
(flymake-tests--call-with-fixture): Stop using ‘ert-resource-file’.
This patch implements some of my suggestions in Bug#8545,
with further changes suggested by Eli Zaretskii (Bug#43439).
* src/doprnt.c: Improve comments.
(SIZE_BOUND_EXTRA): Now at top level, for parse_format_integer.
(parse_format_integer): New static function, containing some of
the old doprnt. Fix a bug that caused doprnt to infloop on
formats like "%10s" that Emacs does not use. We could simplify
doprnt further if we dropped support for these never-used formats.
(doprnt_nul): New function.
(doprnt): Use it. Change doprnt API to exit when either it finds NUL
or reaches the character specified by FORMAT_END. In the typical case
where FORMAT_END is null, take just one pass over FORMAT, not two.
Assume C99 to make code clearer. Do not use malloc or alloca to
allocate a copy of the format FMTCPY; instead, use a small fixed-size
array FMTSTAR, and use '*' in that array to represent width and
precision, passing them as separate int arguments. Use eassume to
pacify GCC in switch statements.
* lisp/wid-edit.el (restricted-sexp widget): New :value-to-external
function. If value is not in the internal format, then we might be
dealing with a bad default value for the widget, so display a warning
about that (bug#25152).
Per bug#43543. Now uses logical lines, not visual lines.
* lisp/emacs-lisp/eldoc.el (eldoc-echo-area-use-multiline-p): Rework
semantics.
(eldoc--echo-area-substring): New helper.
(eldoc--echo-area-prefer-doc-buffer-p): New helper.
(eldoc-display-in-echo-area): Rework using new helpers.
The new name makes it consistent with other variables controlling the
display of ElDoc documentation in the echo area.
Per bug#43543.
* etc/NEWS (Eldoc): Rename eldoc-display-truncation-message to
eldoc-echo-area-display-truncation-message.
* lisp/emacs-lisp/eldoc.el
(eldoc-echo-area-display-truncation-message): Rename from
eldoc-display-truncation-message.
(eldoc-display-in-echo-area): Use new variable name.
* lisp/time.el (world-clock--timer): New variable.
(world-clock): Save timer to above variable when it is started.
(world-clock-cancel-timer): Delete timer saved in variable instead of
searching for the function name.
This reverts commit a497b8e4a4.
This conversion to lexical-binding broke the eval specification,
documented in the ELisp manual. We will probably want to add tests
for that before we can confidently convert this to lexical-binding.
Problem reported by Mattias Engdegård <mattiase@acm.org>.
