This simplifies the GC code, as this was the only field in the charset
struct that referenced the GC heap. Without it, we no longer need to
trace the charset_table.
* src/charset.h (struct charset.attributes): Removed.
(charset_attributes_getter): New helper.
(CHARSET_ATTRIBUTES): Use it.
* src/charset.c (charset_attributes_table): New.
(Fdefine_charset_internal): Place attrs in charset_attributes_table.
(syms_of_charset): Initialize charset_attributes_table.
(mark_charset): Deleted.
* src/pdumper.c (dump_charset): Skip attributes field.
* src/lisp.h (mark_charset): Deleted.
* src/alloc.c (garbage_collect): mark_charset no longer needed.
Eliminate 'vtable--limit-string' in favor of the more efficient
'truncate-string-pixelwise'. Remove extraneous pre-measurement
calls to 'string-pixel-width' and ellipsis concatenation as
'truncate-string-pixelwise' does both.
The 'make-vtable' 'ellipsis' keyword can be a string to override
the default returned by 'truncate-string-ellipsis'.
* lisp/emacs-lisp/vtable.el (vtable--ellipsis): New defun.
(vtable-insert-object, vtable--insert): Use 'vtable--ellipsis'.
(vtable--insert-line, vtable--insert-header-line): Call
'truncate-string-pixelwise' instead of 'vtable--limit-string'.
(vtable--limit-string): Remove function.
* test/lisp/emacs-lisp/vtable-tests.el
(test-vtable--limit-string-with-face-remapped-buffer): Remove
test, obsoleted by misc-test-truncate-string-pixelwise.
* doc/misc/vtable.texi: Document that :ellipsis can be a string.
* lisp/files.el (find-sibling-file-search): Following expansion
of each EXPANSION, advance the search start position to reflect
the actual length of the expanded text (the updated string), not
the length of the "\\([&0-9]+\\)" (the string before expansion).

This provides limited support for window-specific overlay properties.
To complete it, we still need to add support for it to
`next/previous-single-char-property-change`.
* lisp/emacs-lisp/cursor-sensor.el (cursor-sensor--intangible-p):
Add `window` argument.
(cursor-sensor-tangible-pos, cursor-sensor--detect):
Pass `window` argument to the functions
looking for overlay properties.
On some profiles (after disabling syntax and refined
fontification), this was taking >90% of the time to fontify a buffer.
* lisp/vc/diff-mode.el (diff--git-preamble-overlay)
(diff--git-footer-overlay): New variables.
(diff--git-preamble-end, diff--git-footer-start): Use them to cache
the result.
See https://lists.gnu.org/archive/html/emacs-devel/2026-03/msg00567.html.
* test/lisp/use-package/use-package-tests.el (use-package-test-normalize/:vc):
Drop or change expected to match change that interprets a string
argument to :vc in the same manner as 'package-vc-install.
* lisp/progmodes/elisp-mode.el (elisp-fontify-symbol): Mark
the 'cursor-sensor-functions' property as 'rear-nonsticky',
to adapt to 'cursor-sensor-mode' taking into account
property stickiness since f4a1c00656. See also bug#80593.
* lisp/whitespace.el (whitespace-global-mode-buffers): New custom
option.
(whitespace-enable-predicate): Use it.
(whitespace-global-modes): Refer to the new option.
* doc/lispref/windows.texi (Window Sizes):
* src/window.c (Fwindow_body_height, Fwindow_total_height)
(Fwindow_total_width, Fwindow_body_width): Clarify that window
dimensions are returned in canonical columns and lines.
(Bug#80620)
This minor mode configures hs-minor-mode to use
indentation-based folding.
* lisp/progmodes/hideshow.el (hs-hideable-block-p): New
function.
(hs-indentation-respect-end-block): New option.
(hs-indentation--store-vars): New variable.
(hs-cycle-filter, hs-get-first-block-on-line, hs-get-near-block)
(hs-find-block-beg-fn--default): Adapt code to use
'hs-hideable-block-p'.
(hs-block-positions): Update.
(hs-indentation-mode): New minor mode.
* doc/emacs/programs.texi (Hideshow): Update documentation.
* etc/NEWS: Announce changes
* test/lisp/progmodes/hideshow-tests.el: Add 'require'.
(hideshow-check-indentation-folding): New test.
Eliminate an annoying event-loop delay after dropping into an
Emacs window.
* src/nsterm.m: ([EmacsView performDragOperation:]): Kick the
event loop after posting the DRAG_N_DROP_EVENT.
* lisp/simple.el (blink-matching-paren-offscreen): Inherit from
show-paren-match face.
(blink-paren-open-paren-line-string): Add blink-matching-paren-offscreen
face properties to opening paren instead of replacing original
fontification.
* lisp/paren.el (show-paren-context-when-offscreen): Mention
blink-matching-paren-highlight-offscreen in docstring.
* src/widget.c (EmacsFrameRealize): Assign bit_gravity, and use
the value of NorthWestGravity which matches the GTK3 behavior,
and the general intuition that window's contents should move
with its top-left corner. The result is that the frame is not
blinking during resizing (bug#80369).
* src/xfns.c (x_window) [!USE_X_TOOLKIT]: Change bit_gravity from
StaticGravity to NorthWestGravity as well, to match the others.
This makes :vc behave more like 'package-vc-install'.
* lisp/use-package/use-package-core.el (use-package-normalize/:vc):
Translate :vc arguments that are just a string into a minimal
package specification containing only a :url field, thus
preventing a type error down the line.
Further to bug#80428, they are no longer used since commit of
2018-08-05 "Simplify regex-emacs code by assuming Emacs".
Suggested by Pip Cet <pipcet@protonmail.com>.
* src/conf_post.h [emacs] (RE_TRANSLATE_TYPE): Remove;
no longer used except under lib-src.
[emacs] (RE_TRANSLATE): Remove; redefined in src/regex-emacs.c.
* doc/lispref/lists.texi:
* lisp/emacs-lisp/let-alist.el (let-alist): Improve docs.
Namely, clarify that 'let-alist' does not "see" symbols
introduced by macro-expansion in its body, and that the
generated code looks up symbols in the alist whether or not
they are actually used in runtime.
See also bug#79706 for some relevant discussion.
* doc/lispref/lists.texi (Building Lists): Document it.
* etc/NEWS: Mention it.
* lisp/emacs-lisp/shortdoc.el (list): Demonstrate it.
* lisp/subr.el (ensure-proper-list): Add it.
* doc/emacs/custom.texi (Newcomers Theme): Move to the beginning
of the node, so as to be visible even when the Emacs frame is
too small and wrap it in a conditional to not print the message
in non-Info outputs.
