* lisp/emacs-lisp/byte-opt.el (byte-optimize-lapcode):
Clean up and simplify an old jump-to-conditional-jump rule that was
originally intended for moving loop branches from the top to the bottom,
but is today not much used because it relies on other transformations
only made for dynbound variables.
This change should not alter code generation.
Discussed in
https://lists.gnu.org/archive/html/emacs-devel/2025-12/msg00903.html.
* lisp/progmodes/project.el (project-files) <vc>: Look up the
value of 'project-vc-ignores' inside DIR rather than project root.
This allows this variable to be applied in external dirs as well.
(project-ignores) <vc>: Do likewise.
(project--value-in-dir): Ensure that DIR has a trailing slash.
The caller might pass the value without slash if produced
differently.
* test/lisp/progmodes/project-tests.el
(project-vc-ignores-in-external-directory): New test.
(project-vc-supports-files-in-subdirectory): Update the test,
considering the subtle change in behavior: the directory DIR
directly includes a .dir-locals.el which sets project-vc-ignores,
which wasn't previously applied because it wasn't set in the root.
This is easier to understand and easier to customize.
* lisp/vc/diff-mode.el (diff-mode-shared-map): Move bindings for
"W", "w", "A", "r" and "R" from here ...
(diff-mode-read-only-map): ... to here, a new map.
(diff-mode-map): Bind diff-mode-shared-map to "ESC".
(diff-read-only-map): Make a composed map from
diff-mode-read-only-map instead of diff-mode-shared-map.
Rework the implementation of `project-files<vc>` so as to
delegate more to the `project-list-files` operation, including
the default implementation.
This can change the behavior in some cases, because it changes
which ignore settings apply where and also it can now use
a dedicated VC backend implementation even for directories
that are outside of the project's root. But the effect should
hopefully be marginal and rather positive by making the behavior
more "regular".
* lisp/progmodes/project.el (project-vc--backend): New function.
(project-files) <vc>: Use it. Call VC's `project-list-files` operation
for all dirs with a backend and remove the `vc-not-supported` fallback.
Inline the `project--dir-ignores` call.
(vc-default-project-list-files): New function, extracted from
`project-files<vc>`.
(vc-git-project-list-files): Use it instead of signaling `vc-not-supported`.
(project--vc-ignores): New function, extracted from `project-ignores<vc>`.
Remove the `vc-not-supported` since the operation has a default
implementation. Use DIR's `ignore-completion-table` regardless
if we're at the root of the project.
(project-ignores) <vc>: Use it.
In particular, don't auto-resize in flymake-start if the current buffer
already has suitable margins. Otherwise it's impossible to operate two
windows showing the same buffer with different scrolls while using
Flymake.
Also, when attempting to restore margins, remember to actually apply
them.
* lisp/progmodes/flymake.el (flymake--original-margin-width)
(flymake--suitably-fringed-p, flymake--bs-display)
(flymake--restore-margins, flymake-restore-margins): Move to
separate section. Rework.
(flymake--suitable-margin-width, flymake--apply-margins)
(flymake--appropriate-margin): New helpers.
This should have been updated along with the recent change to
make the UPSTREAM-LOCATION argument to the incoming-revision
backend API function optional.
* lisp/vc/vc.el (vc--maybe-read-upstream-location): Default to
returning nil, not an empty string.
* lisp/calendar/calendar.el (calendar-redraw)
(calendar-other-month): Make sure that the mode line is updated
after cursor motion in case 'date' is used in
'calendar-mode-line-format'.
(calendar-set-date-style): Delete call to
calendar-update-mode-line because it is called in calendar-draw.
(calendar-generate-window): Delete calls to
calendar-update-mode-line and calendar-cursor-to-visible-date.
It's better for the caller to do it.
(calendar-basic-setup): Update cursor position and mode line.
* lisp/calendar/cal-move.el (calendar-goto-today): Delete
calendar-update-mode-line because calendar-move-hook is called
last. This is consistent with other cal-move commands.
* test/lisp/calendar/calendar-tests.el
(calendar-test-date-in-mode-line): New test.
* lisp/emacs-lisp/track-changes.el (track-changes-undo-only): New var.
(track-changes-fetch): Bind it.
(track-changes--state): New slot `undo`.
(track-changes--after): Set it.
* lisp/vc/diff-mode.el (diff--track-changes-function): Use the
new var.
* doc/lispref/text.texi (Tracking changes): Mention
`track-changes-undo-only`.
* lisp/vc/vc.el (vc--read-branch-to-log): New function.
(vc-print-root-branch-log): Rewrite to use
vc--read-branch-to-log and vc--with-backend-in-rootdir.
(vc-print-fileset-branch-log): New command.
* lisp/vc/vc-dir.el (vc-dir-mode-map):
* lisp/vc/vc-hooks.el (vc-prefix-map):
(vc-menu-map): Bind it.
* doc/emacs/maintaining.texi (VC Change Log):
* etc/NEWS: Document it.
* lisp/vc/vc.el (vc--read-limit): New function.
(vc-print-root-log): Call it.
(vc-print-log): Call it. Modernize style. Fix docs regarding
LIMIT: it defaults to vc-log-show-limit only for interactive
calls.
Zero-length strings are just 'empty'; 'null' can be confusing in several
ways.
* lisp/subr.el (split-string, string-lines):
* doc/lispref/strings.texi (Creating Strings):
Change argument names from 'omit-nulls' to 'omit-empty'.
* doc/lispref/strings.texi (Creating Strings):
* lisp/subr.el (split-string):
Make it clear that the SEPARATORS argument should not match the empty
string, since the behaviour was entirely an artefact of the original
implementation in this case; it makes little sense otherwise.
Clean up the examples for conciseness and do not waste space on
irrelevant details.
* lisp/frame.el (set-frame-size-and-position): Correctly
interpret width and height of workarea as returned by
'frame-monitor-attributes'. If LEFT or RIGHT are floats,
position FRAME according to left/top position of workarea.
`noindent` is more precise than what we did since it gives more
info to the caller: `indent-for-tab-command` can treat it
differently (e.g. fall back to `indent-relative`) than `indent-region`.
* lisp/nxml/nxml-mode.el (nxml-compute-indent-in-token): Use `noindent`
in CDATA.
(nxml-compute-indent-in-delimited-token): Remove CDATA case, not used
any nmore.
Some of the fixes are to continue to use American
rather than British spelling.
* doc/misc/modus-themes.org (my-modus-themes-engraved-faces):
Fix misspelled ‘:foreground’s.
* etc/themes/modus-themes.el (modus-themes-faces):
Fix misspelled ‘modus-themes-bold’.
* lisp/emacs-lisp/rx.el (rx--normalize-char-pattern):
Rename from rx--normalise-char-pattern.
(rx--optimize-or-args): Rename from rx--optimise-or-args.
* lisp/frame.el (frame--special-parameters):
Fix misspelled "right-divider-width".
* lisp/net/tramp.el (tramp-fingerprint-prompt-regexp):
Use American spelling “centered”, to match current libfprintf.
* lisp/org/org-fold-core.el (org-fold-core--optimize-for-huge-buffers):
Rename from org-fold-core--optimise-for-huge-buffers.
(org-fold-core-update-optimization):
Rename from org-fold-core-update-optimisation,
leaving an alias behind.
(org-fold-core-remove-optimization):
Rename from org-fold-core-remove-optimisation,
leaving an alias behind.
* lisp/org/org.el (org-advertized-archive-subtree):
This alias is now obsolete.
* lisp/play/zone.el (zone-ignored-buffers):
Fix misspelling of ‘zone--buffer-encrypted-p’.
* lisp/progmodes/csharp-mode.el (csharp-ts-mode-faces):
Fix misspelling of ‘csharp’ group.
* lisp/vc/vc.el (vc-clonable-backends-custom-type):
Rename from vc-cloneable-backends-custom-type,
leaving an alias behind.
* test/lisp/emacs-lisp/bytecomp-tests.el:
(bytecomp-tests--warn-arity-non-compiled-callee):
Rename from bytecomp-tests--warn-arity-noncompiled-callee.
(bytecomp-test-defface-spec): Reword a deliberate misspelling
of “default” that is so common I don’t want it to pollute the
spelling dictionary.
* test/lisp/emacs-lisp/package-vc-tests.el:
(package-vc-tests-preserve-artifacts):
Rename from package-vc-tests-preserve-artifacts.
* test/lisp/eshell/em-prompt-tests.el:
(em-prompt-test/forward-backward-paragraph-1):
Reword a deliberate misspelling of “goodbye” that is so common I
don’t want it to pollute the spelling dictionary.
* lisp/net/tramp-adb.el (tramp-adb-do-ls): New function.
(tramp-adb-handle-file-attributes)
(tramp-adb-handle-directory-files-and-attributes)
(tramp-adb-handle-file-name-all-completions): Use it. (Bug#80054)
In large buffers, responses to textDocument/documentHighlight
requests may return thousands of occurrences. Avoid incurring
expensive eglot--lsp-position-to-point calls, by restricting the
highlights to visible region in the active window.
* lisp/progmodes/eglot.el (eglot-highlight-eldoc-function):
Rework.
Fix the case when an image file is visited in the directory with
image files without image file extensions, and 'dired-movement-style'
is non-nil, and 'dired-next-line' wraps to the top of the dired buffer,
doesn't find the next image file and goes into an infinite loop.
Remember the original file name and exit the loop when after wrapping
'dired-next-line' reaches the original file.
When moving to the middle of an intangible chunk, and either end
of the chunk would result in a movement in the right direction, prefer
the shorter movement, since it's easier for the users to repeat a
movement than to "go back".
(see https://lists.gnu.org/archive/html/emacs-devel/2025-12/msg00686.html)
* lisp/emacs-lisp/cursor-sensor.el (cursor-sensor-tangible-pos):
Refine the choice.
* lisp/emacs-lisp/cursor-sensor.el (cursor-sensor-tangible-pos):
Prefer a tangible position, even if it means going in the wrong
direction; and don't favor shorter movement.
The main purpose is to make the code more symmetric and make it
easier to tweak the behavior, compared to the previous code which
focused on moving always in the direction of the overall motion.
* lisp/emacs-lisp/cursor-sensor.el (cursor-sensor-tangible-pos):
Rewrite and allow movement in both directions, tho with (hopefully)
minimal changes in behavior.
