* lisp/minibuffer.el (define-completion-category): New function.
(completion-category-get): New function, implements completion
category property lookup with (multiple) inheritance.
(completion-metadata-get, completion--styles)
(completion--cycle-threshold): Use it.
(completion-category-defaults): Mention it in docstring.
Remove entry for 'project-buffer' category, and instead...
* lisp/progmodes/project.el: ...have 'project-buffer' inherit
from 'buffer'.
* test/lisp/minibuffer-tests.el
(completion-category-inheritance): New test.
* etc/NEWS: Announce support for category inheritance.
The previous change actually introduced a bug in a closely
related but distinct place. We need to address the off-by-one
in the 'substring' call, not the 'add-face-text-property'.
* lisp/progmodes/eglot.el (eglot--sig-info): Fixup.
* lisp/isearch.el (isearch-mode): Don't override
'isearch--saved-local-map' when 'overriding-terminal-local-map'
was already set to 'isearch-mode-map' in a previous call.
(with-isearch-suspended): Don't call the function 'isearch-mode'
when the variable 'isearch-mode' is already non-nil.
* lisp/emacs-lisp/macroexp.el (macroexp--obsolete-warning): `instead`
can be a list.
* lisp/dom.el (dom-text, dom-texts): Fix obsolescence declaration.
The correct Emacs executable to use for
'elisp-flymake-byte-compile' is not necessarily the running
Emacs. For example, when editing trunk with Emacs 30,
various Lisp changes will cause spurious flymake warnings.
Add 'elisp-flymake-byte-compile-executable' to allow
customizing this.
* lisp/progmodes/elisp-mode.el
(elisp-flymake-byte-compile-executable)
(elisp-flymake-byte-compile--executable): Add. (Bug#79342)
(elisp-flymake-byte-compile): Invoke
'elisp-flymake-byte-compile--executable'.
* etc/NEWS: Announce the change.
Revert "Avoid duplicating strings in pcm--merge-completions",
commit b511c38bba. It broke
existing behavior, now covered by tests adding in this commit.
* lisp/minibuffer.el (completion-pcm--merge-completions):
* test/lisp/minibuffer-tests.el (completion-pcm-test-anydelim):
(completion-pcm-bug4219):
* lisp/vc/diff-mode.el (project-root): Declare.
(diff-find-matching-buffer): New function.
(diff-mode): Use it.
* doc/emacs/vc1-xtra.texi (Other Working Trees): Document
'C-x v w w' in diff-mode buffers.
* lisp/vc/vc-bzr.el (vc-bzr-incoming-revision):
* lisp/vc/vc-hg.el (vc-hg-incoming-revision):
* lisp/vc/vc.el (vc-diff-incoming, vc--incoming-revision): New
REFRESH optional argument.
(vc-default-log-incoming): Pass it.
* lisp/vc/vc-git.el (vc-git-incoming-revision): New REFRESH
optional argument. When nil, use cached info (bug#62940).
* lisp/tab-line.el (tab-line-define-keys): New defcustom.
(tab-line--define-keys, tab-line--undefine-keys):
New functions that explicitly bind commands from
'tab-line-mode-map' to 'ctl-x-map'.
(tab-line-mode-map): Leave this keymap empty by default
to avoid breaking 'ctl-x-map' (bug#79323).
(global-tab-line-mode): Call either 'tab-line--define-keys'
or 'tab-line--undefine-keys'.
This feature was tweaked and last tested with a 2019 edition of
the 'ccls' LSP. The spec does not clearly specify this number
to be 0-indexed, but it would make sense that it would be so.
So there's not need to 1+ - correct the numbers at all before
using them in substring. This would fix the Haskell server use
of this feature (which is bug#79259)
* lisp/progmodes/eglot.el (eglot--sig-info): Fix likely off-by-1.
Escape literal % characters in Eglot URIs
Otherwise, a literal % in a file-name will be interpreted (by the
language server) as if it were a part of a percent-encoded sequence.
See Bug#78984 for context on why `url-path-allowed-chars' cannot be
changed to escape literal % characters.
* lisp/progmodes/eglot.el (eglot--uri-path-allowed-chars): Escape %,
remove the redundant variable definition.
* test/lisp/progmodes/eglot-tests.el (eglot-test-path-to-uri-escape):
test it.
Command edebug-bounce-to-previous-value uses the previous value
observed while single-stepping or evaluating an expression to
bounce point in the outside current buffer to the buffer
position corresponding to that value.
* lisp/emacs-lisp/edebug.el (edebug-previous-value): Add
variable.
(edebug-compute-previous-result, edebug-eval-expression): Update
it.
(edebug-bounce-to-previous-value): Add command.
(edebug-mode-map): Add keybinding for the new command, replacing
the binding of "P" to edebug-view-outside.
(edebug-mode-menus): Add menu entry for the new command.
* doc/lispref/edebug.texi (Edebug Views): Add documentation.
* test/lisp/emacs-lisp/edebug-resources/edebug-test-code.el
(edebug-test-code-bounce-point): Add test code.
* test/lisp/emacs-lisp/edebug-tests.el
(edebug-tests-bounce-outside-buffer)
(edebug-tests-bounce-outside-point)
(edebug-tests-bounce-outside-mark)
(edebug-tests-bounce-record-outside-environment)
(edebug-tests-should-have-bounced-to): Add infrastructure to
test bounces.
(edebug-tests-check-keymap): Update tests to new key bindings.
(edebug-tests-bounce-point)
(edebug-tests-bounce-to-previous-value)
(edebug-tests-bounce-to-previous-non-position): Add tests.
(edebug-tests-evaluation-of-current-buffer-bug-19611): Clean up
side effects. (Bug#79288)
* lisp/progmodes/lua-ts-mode.el (lua-ts--comment-font-lock):
Apply 'font-lock-comment-delimiter-face' to the entire span of
initial dashes. In particular, this improves the appearance of
LuaCATS and EmmyLua style annotations which use "---".
* test/lisp/progmodes/lua-ts-mode-resources/font-lock.lua:
Add tests. (Bug#79258)
* doc/misc/calc.texi (Customizing Calc): Document the new option.
* etc/NEWS: Document the new option.
* lisp/calc/calc.el (calc-inhibit-startup-message): New option to
inhibit Calc’s startup message.
(calc): Respect the option in Calc’s startup code.
* test/lisp/calc/calc-tests.el (ert): Require ert-x for
'ert-with-message-capture'.
(calc-inhibit-startup-message): Test the new user option.
(markdown-ts--range-settings): Move embed settings
for html/toml/yaml to 'markdown-ts-setup'.
(markdown-ts-setup): Append range rules to 'treesit-range-settings'
only when grammars for html/toml/yaml are installed.
* lisp/org/org-habit.el (org-habit-build-graph): Rewrite without using
string mutation (using vectors instead), fixing a bug where
org-habit-completed-glyph and org-habit-today-glyph wouldn't display
properly if in the U+0080..00FF range, discovered by the more restricted
string mutation.
Reported by Daniel Mendler in
https://lists.gnu.org/archive/html/emacs-orgmode/2025-08/msg00224.html
This fixes a failure in 'test-custom-opts' caused by both strings
and integers being used for 'lua-prefix-key'.
* lisp/progmodes/lua-mode.el (lua-prefix-key): Convert option to
'key-sequence' type.
(lua-mode-map, lua-prefix-key-update-bindings, lua-set-prefix-key)
(lua--customize-set-prefix-key): Adjust to the change of type for
'lua-prefix-key'.
(lua-prefix-mode-map): Use 'defvar-keymap'. (Bug#79335)
