We add a symbol property 'elisp-scope-variable-spec', which
holds a specification for the values of a variable with that
property. For example, (put 'foo '(symbol . face)) says
that the value of variable 'foo' is a face name.
This allows elisp-scope.el to analyze forms such as
(setq foo 'bar) and (let ((foo 'bar)) ...) more accurately.
This is also used for analyzing macros that let-bind (one of)
their arguments to a specific special variable, such as
'with-connection-local-application-variables'.
We initially add this new property to some common variables.
* lisp/emacs-lisp/elisp-scope.el: Add
'elisp-scope-variable-spec' property to
'coding-system-for-read/write' and 'major-mode'.
(elisp-scope--variable-spec): New defsubst.
(elisp-scope--let-1, elisp-scope-let*, elisp-scope-setq):
Use it.
* test/lisp/progmodes/elisp-mode-resources/semantic-highlighting.el:
Add test form.
* lisp/frame.el (get-mru-frame): New defun.
* src/frame.c (delete_frame): Call 'get-mru-frame' (when force
is not Qnoelisp) to select the most recently used frame that is
not the deleted frame as the candidate to select.
(syms_of_frame): Qget_mru_frame new DEFSYM.
* doc/lispref/frames.texi: Document the new functions.
* etc/NEWS: Announce the new functions.
* src/treesit.c (ts_tree_cursor_copy) [WINDOWSNT]: Define and load
from the DLL if 'ts_tree_cursor_goto_previous_sibling' is not
available. This fixes the MS-Windows build broken by the last
change here. (Bug#80108)
Now we use treesit_traverse_sibling_helper when it exists, and
use the old code otherwise. So we still support older
tree-sitter versions.
* configure.ac (LIBSYSTEMD_CFLAGS): Add back old config checking
for the malloc function. Add another check for
ts_tree_cursor_goto_previous_sibling.
* src/treesit.c: (treesit_traverse_sibling_helper): Add back the
old code that doesn't require
ts_tree_cursor_goto_previous_sibling.
* lisp/vc/vc.el (vc-root-diff-outgoing-base)
(vc-diff-outgoing-base, vc-log-outgoing-base)
(vc-root-log-outgoing-base): Rename from these ...
(vc-root-diff-outstanding, vc-diff-outstanding)
(vc-log-outstanding, vc-root-log-outstanding): ... to these.
All uses changed.
* lisp/progmodes/project.el (project--delete-zombie-projects):
Bind tramp-error-show-message-timeout to nil, to instruct Tramp
not to display the "failed to connect" and its message, hiding the
current prompt (bug#80340).
* lisp/window.el (split-width-threshold): Change the default value
from 160 to 150 (bug#80050).
(split-window-preferred-function):
Mention 'split-window-preferred-direction' in the docstring.
* doc/misc/tramp.texi (External packages): Mention handler-bind to
trap for remote-file-error.
(Traces and Profiles): Explain tramp-error-show-message-timeout.
- Add several autoload cookies.
- Separate public API hook used internally into a private hook.
- Fix thinko in setting up the special event sleep-event handler.
- Probe the D-Bus session bus for screen saver support during
enable.
* lisp/system-sleep.el (system-sleep--set-back-end): Move dbus
endpoint tests into the system-sleep--enable dbus
implementation.
(system-sleep--event-after-hook-functions): New private hook.
(system-sleep--dbus-has-screensaver): New defvar.
(system-sleep--sleep-event-handler): Call the new private hook.
(system-sleep--sleep-event-function): Remove. Use
'system-sleep--sleep-event-handler'.
(system-sleep--enable): Use the internal hook.
(system-sleep--enable): [dbus] Probe session bus for screen
saver support.
(system-sleep--disable): Remove the new internal hook.
(system-sleep--block-sleep): Call screen saver dbus endpoint
only when screen saver support is known to exist.
Without this fix, a 64-bit build on Ubuntu 25.10 x86-64 failed
when the libselinux1-dev:i386 package (providing <selinux/selinux.h>)
was installed but the libselinux1-dev package (providing
/usr/lib/x86_64-linux-gnu/libselinux.so) was not.
The first symptom was when compiling emacsclient:
‘/usr/bin/ld: ../lib/libgnu.a(file-has-acl.o): in function
`get_aclinfo': .../lib/file-has-acl.c:247:(.text+0x4d8): undefined
reference to `getfilecon'’.
* configure.ac: Default with_selinux to maybe, not to yes.
Defer our SELinux configuration to after Gnulib’s, so that
we handle any SELinux problems that Gnulib discovers.
project-try-vc--search in a submodule directory tries to find the git
root directory, so the local variable root would be set to nil if it
didn't exist. Calling project--vc-merge-submodules-p on nil would lead
to a crash, so now the while loop aborts beforehand.
* lisp/progmodes/elisp-mode.el
(elisp--highlight-function-argument): Handle special usage
syntax correctly when scanning usage arguments using
'forward-sexp' (bug#8432). Before binding 'origin', skip over
blanks, so as not to highlight them, and to move immediately
before any possible opening square brackets. After binding
'origin' and before calling 'forward-sexp', skip over opening
square brackets, so as to highlight them. After calling
'forward-sexp' and before setting 'start' and 'end', skip over
closing square brackets and periods, so as to highlight them.
* lisp/progmodes/elisp-mode.el
(elisp--highlight-function-argument): Use 'forward-sexp' to move
over usage arguments, handling parenthesized argument patterns
monolithically (bug#8432). Set 'start' and 'end' to the
beginning and end, respectively, of the usage argument.
* lisp/progmodes/elisp-mode.el
(elisp--highlight-function-argument): Insert 'args' into
temporary buffer to prepare for better handling of usage
arguments (bug#8432). Move point after the first opening
parenthesis of the arguments string. In the loop, let `origin'
track the point. No functional change.
* lisp/calendar/diary-icalendar.el (diary-icalendar--tz-is-utc-p): New
function.
(diary-icalendar-convert-time-via-strategy): Don't expect a VTIMEZONE
for UTC times.
(diary-icalendar-export-region): Don't generate a VTIMEZONE for 'local
export strategy in UTC.
* test/lisp/calendar/diary-icalendar-tests.el
(diary-icalendar-test-entry-parser): Don't generate a VTIMEZONE for
'local export strategy in UTC.
* lisp/delsel.el (delete-selection-replacement-face): Delete var.
(delete-selection-replacement): New face, to replace it.
(delsel--replace-overlay, delsel--replace-text): Delete vars and ...
(delete-selection--replacement-text): ...use this single var instead.
(delete-selection--replacement-cursor): New function.
(delete-active-region): Use it with `cursor-sensor-mode` to avoid the
overlay lingering too long.
(delete-selection--replacement-text): New function extracted from
`delete-selection-repeat-replace-region`, with adjustments to account
for the above changes.
(delete-selection-repeat-replace-region): Use it.
* lisp/emacs-lisp/cursor-sensor.el (cursor-sensor--detect): Do use
`get-pos-property` when it works. Fix the `missing-p` subfunction
so as not to get fooled by a missing property at END.
This patch was sent back in 2014 as part of bug#18886.
* lisp/delsel.el (delsel--replace-text-or-position): Delete var.
(delete-selection-replacement-face): New defcustom.
(delsel--replace-text, delsel--replace-overlay): New vars.
(delete-active-region, delete-selection-repeat-replace-region):
Use overlay to track replacement text instead of abusing the
undo-list; this allows the text to be edited before it is
used for substitutions. Add highlight to the replacement text.
Now that json.el uses the new sort calling convention, there's no
need to prefer string< over value<, which may even run faster.
Suggested by Mattias Engdegård <mattias.engdegard@gmail.com>.
* lisp/json.el (json-encoding-object-sort-predicate): Mention value<
in docstring.
(json-pretty-print-buffer-ordered, json-pretty-print-ordered): Use
value< in place of string<.
* test/lisp/json-tests.el (test-json-encode-hash-table-sort): Use
value< as json-encoding-object-sort-predicate in at least one test.
