See https://lists.gnu.org/archive/html/emacs-devel/2025-11/msg00145.html
for the related discussions.
* nt/mingw-cfg.site (ac_cv_func_acl_entries): Set to "yes" to
disable compilation of lib/acl_entries.c on MinGW.
* lib/acl_entries.c (acl_entries): Revert last change, as it is no
longer needed.
Chdir once and for all at the beginning to simplify the code.
Eliminate some redundant `expand-file-name`s and fix a broken use
of `expand-file-name` where we passed a list as second arg.
* lisp/emacs-lisp/loaddefs-gen.el (loaddefs-generate): Rename DIR to
DIRS, to clarify that it can be a list. Use `ensure-list`.
Don't pass DIR(S) directly to `expand-file-name`.
Remove redundant `expand-file-name`.
(loaddefs-generate--excluded-files): Add sanity checks.
Return relative file names since `loaddefs-generate` will make them
absolute anyway. Simplify.
(loaddefs-generate--emacs-batch): Chdir to `lisp-directory` and
simplify the rest accordingly.
This fixes problems in some cases of out-f-tree builds
(bug#79694, bug#62099, bug#64806).
The use of true names in `load-history` dates back to to commits
33d74677e7 and 6bb6da3ec1 by Alan Mackenzie <acm@muc.de> in
May 24 2006, but that was reverted by Paul Eggert's commit
dff4f9c759 on Sep 18 2019.
* lisp/startup.el (command-line): Don't `file-truename` `lisp-directory`.
* src/lread.c (syms_of_lread) <load-history>: Adjust docstring,
to reflect the fact that the files there aren't "true names".
* doc/lispref/loading.texi (Hooks for Loading): Adjust accordingly.
Also massage the text to reflect the fact that nowadays features are
more common than file names as arguments to `with-eval-after-load`.
This results in a healthy reduction of .elc file size (> 300 KiB saved)
as well as less memory use.
* lisp/emacs-lisp/bytecomp.el (byte-compile-get-constant):
Use 'equal-including-properties' as equivalence relation for all
constants, not just strings.
* etc/NEWS: Mention it. Strictly speaking it's not an incompatible
change because it doesn't break any earlier promises, but for people
having code that made incorrect assumptions, this provides a useful
explanation.
* lib/acl_entries.c (acl_entries): Make it no-op for MinGW, as it
was before. Without this, acl_entries doesn't compile on MinGW.
* nt/gnulib-cfg.mk (OMIT_GNULIB_MODULE_issymlink)
(OMIT_GNULIB_MODULE_issymlinkat): Disable these Gnulib modules.
* doc/misc/eglot.texi (Eglot Features): Add comma after @xref.
* msdos/sed2v2.inp (GNULIB_ISSYMLINK): Define to 1.
* msdos/sedlibmk.inp (HAVE_RANDOM_H): Undefine, in line with its
deletion from gnulib.mk.
(GL_GNULIB_STRINGEQ): Define to 1.
* src/msdos.c (careadlinkat): NULL terminate at the end of the
data written, not one character beyond the same.
* src/timefns.c (Fdecode_time, Fencode_time)
(Fcurrent_time_string): Do not bother to preserve errno around
tzfree calls, as Gnulib now does that for us.
* admin/merge-gnulib (GNULIB_MODULES): Add stringeq.
With current Gnulib it is already present as in indirect dependency;
listing it here because Emacs now depends on it directly.
* lib-src/ebrowse.c, lib-src/etags.c:
(streq): Remove, as Gnulib defines this now.
* lib/fseterr.c, lib/fseterr.h, lib/issymlink.c, lib/issymlink.h:
* lib/issymlinkat.c, lib/stdio-consolesafe.c, lib/string.c:
* m4/fseterr.m4, m4/gettext_h.m4, m4/stringeq.m4:
New files from Gnulib.
* src/conf_post.h (tzfree) [__ANDROID_API__ >= 35]: Remove.
* lisp/emacs-lisp/cond-star.el (cond*): Document 'bind-and*'.
(bind-and*): Add a stub to raise an error if 'bind-and*' is used
outside of 'cond*'.
(cond*-convert-condition): Implement a new type of condition.
* lisp/userlock.el (ask-user-about-lock): Use 'read-char-choice'
instead of 'read-char'.
* lisp/subr.el (read-char-choice-with-read-key): Add fallback
cond-branch to show a message with required keys.
Rewrite the format in 'hs-special-modes-alist' to make easier to
exclude some values, add support for settings inheritance
according to current major mode and parents, and support string
hiding for lisp modes.
Bug#79671
* lisp/progmodes/hideshow.el (hs-modes-alist): New variable.
(hs-special-modes-alist): Mark as obsolete.
(hs-forward-sexp-func, hs-adjust-block-beginning)
(hs-find-block-beginning-func, hs-find-next-block-func)
(hs-looking-at-block-start-p-func): Set default values to nil.
(hs-inside-comment-p): Remove function.
(hs-adjust-block-end, hs-treesit-things): New buffer-local
variables.
(hs-block-positions): Minor updates.
(hs--get-mode-value): New function.
(hs-grok-mode-type): Rewrite.
* lisp/progmodes/f90.el (hs-special-modes-alist):
* lisp/progmodes/fortran.el (hs-special-modes-alist):
* lisp/progmodes/icon.el (icon-mode):
* lisp/progmodes/lua-mode.el (lua-mode):
* lisp/progmodes/python.el (python-base-mode):
* lisp/progmodes/verilog-mode.el (verilog-mode):
* lisp/progmodes/vhdl-mode.el (vhdl-hs-minor-mode): Rewrite
settings.
* lisp/progmodes/python.el (python-ts-hs-adjust-block-end-fn):
New function.
* lisp/treesit.el (treesit-hs-block-end)
(treesit-hs-find-block-beginning, treesit-hs-find-next-block)
(treesit-hs-looking-at-block-start-p): Minor updates.
* doc/emacs/programs.texi (Hideshow):
* etc/NEWS: Document changes.
* doc/lispref/objects.texi (Equality Predicates):
Remove incorrect and/or misleading examples, add new ones,
and display them more compactly to save space.
* lisp/frame.el (delete-other-frames): In second round make sure
the candidate frame has not been deleted in the first round to
avoid that 'frame-terminal' and friends throw an error.
* src/xsettings.c (store_config_changed_event, dpyinfo_valid)
(store_font_name_changed, store_tool_bar_style_changed): Tweak
preprocessor conditions to satisfy all builds without warnings.
* test/lisp/emacs-lisp/cl-lib-tests.el (cl-test-ldiff):
* test/lisp/emacs-lisp/seq-tests.el (test-seq-union):
These tests relied on literal constants being unique in the sense of
'eq', and would fail if they stop being that (already the case for
strings).
* test/lisp/erc/erc-scenarios-base-reuse-buffers.el
(erc-scenarios-common--base-reuse-buffers-channel-buffers): Extend some
timeouts.
* test/lisp/erc/erc-scenarios-keep-place-indicator.el
(erc-scenarios-keep-place-indicator--follow): Prefer `ert-skip' here
instead of an :unstable tag because ERC's tests can run locally on some
systems with "SELECTOR=t".
Latest tree-sitter library throws a syntax error if the
predicate names in a query don't end with question mark. So we
made the following change:
:equal changed to :eq?
:match changed to :match?
:pred changed to :pred?
Old names are transparently converted to new names when
expanding patterns.
:match predicate can now take the regexp and the node in any
order: it'll figure out which is which automatically. This way
it works with current Emacs convention (regexp first), as well
as tree-sitter's match convention (regexp second).
* doc/lispref/parsing.texi (Pattern Matching): Update manuel to
use new predicate names.
* src/treesit.c:
(Ftreesit_pattern_expand):
(Ftreesit_query_expand):
(treesit_predicate_match):
(treesit_eval_predicates):
(syms_of_treesit): Use new predicate names.
* test/src/treesit-tests.el (treesit-query-api): Update test.
* src/xsettings.c (store_tool_bar_style_changed): Compile only
under HAVE_GSETTINGS.
(xg_get_system_dark_mode): Compile only under HAVE_GSETTINGS.
* src/gtkutil.c (xg_set_gtk_theme_dark_mode)
(xg_update_dark_mode_for_all_displays, xg_set_initial_dark_mode):
Only compile when HAVE_GSETTINGS is defined.
(xg_create_frame_widgets): Call 'xg_set_initial_dark_mode' only
under HAVE_GSETTINGS.
(xg_create_frame_outer_widgets): Remove unused code. Call
'xg_set_initial_dark_mode' only under HAVE_GSETTINGS.
* src/pgtkselect.c (pgtk_reply_selection_request): Remove unused
variable.
* doc/emacs/frames.texi (Frame Commands): Document
'alter-fullscreen-frames', which is a user option. Fix indexing.
* src/frame.c (syms_of_frame) <alter-fullscreen-frames>: Doc fix.
(Bug#79756)
* src/frame.c (adjust_frame_size): Honor new option
'alter-fullscreen-frames'.
(syms_of_frame) <alter-fullscreen-frames>: New option to
maintain consistent state when attempting to resize fullscreen
frames. Default to 'inhibit' for NS builds because these
resized the frame while leaving the 'fullscreen' parameter alone
(Bug#79704).
(syms_of_frame) <Qinhibit>: Define symbol.
* lisp/cus-start.el (standard): Add customization options for
'alter-fullscreen-frames'
* doc/lispref/frames.texi (Frame Size): Describe new option
'alter-fullscreen-frames'.
* etc/NEWS: Call out new option 'alter-fullscreen-frames'.
* src/gtkutil.h: Declare 'xg_set_gtk_theme_dark_mode',
'xg_update_dark_mode_for_all_displays',
'xg_set_initial_dark_mode'.
* src/gtkutil.c (xg_set_gtk_theme_dark_mode): Toggle PGTK dark mode.
(xg_update_dark_mode_for_all_displays): Toggle PGTK dark mode for all
displays.
(xg_set_initial_dark_mode): Determine PGTK dark mode preference and set.
(xg_create_frame_widgets): Set PGTK dark mode preference for widgets.
(xg_create_frame_outer_widgets): Set PGTK dark mode preference for outer
widgets.
* src/xsettings.h: Declare 'xg_get_system_dark_mode'.
* src/xsettings.c (something_changed_gsettingsCB): Update PGTK dark mode
setting.
(xg_get_system_dark_mode): Determine PGTK dark mode preference.
GSETTINGS_COLOR_SCHEME: Defined and set to "color-scheme".
* etc/NEWS: Document automatic dark mode toggling.
(Bug#79689)
(rcirc-markup-attributes): Delete markup codes straight after
processing it, to correctly handle toggling codes. E.g. when
processing the message "one ^Btwo^B three", we previously
recognised the first interval "^Btwo^B" and moved over the ^B.
Searching for the next range to markup, we would now falsely
recognise "^B three" to be another markup range, instead of it
being the negative toggle. By removing the processed codes, we
avoid this issue. This reverts the functionality removed in
946ceca2, and therefore also re-adds the check to make an
exception to removing a ^O as that code can terminate multiple
markup sequences. (Bug#57383)
* lisp/emacs-lisp/map.el (map-contains-key): Hide old
implementation prior to f60fc128 behind a `fboundp', as the
package is distributed on ELPA and should be backwards
compatible to Emacs 26. (Bug#79711)
* lisp/emacs-lisp/map-ynp.el (map-y-or-n-p): Use the 'read-key'
branch only when the variable 'y-or-n-p-use-read-key' is non-nil.
Add a new cond-branch to read from the minibuffer.
Add a special case when def is nil in a kmacro in batch mode (bug#67836).
* test/lisp/files-tests.el (files-tests--with-buffer-offer-save):
Let-bind 'y-or-n-p-use-read-key' to t.
* doc/lispref/commands.texi (Reading One Event): Mention
'read-char-choice-use-read-key'.
* lisp/emacs-lisp/rmc.el (rmc--show-help): Show non-selected
resized Help window at bottom. Inhibit useless message.
Remove unnecessary call to 'pop-to-buffer'.
(read-multiple-choice): Call 'read-multiple-choice--from-minibuffer'
when 'read-char-choice-use-read-key' is nil.
(read-multiple-choice--from-minibuffer): New function.
* test/lisp/emacs-lisp/rmc-tests.el (test-rmc--with-minibuffer-setup):
New macro.
(test-read-multiple-choice, test-read-multiple-choice-help):
Test both values of 'read-char-choice-use-read-key'.
