Arrange for the library to be usable on older Emacsen, which
includes reducing the noise when `before/after-change-functions`
are badly paired or missing.
Also, since the signal function receives the distance (for `:disjoint`),
we don't need `track-changes--disjoint-threshold`: the signal
function can simply do nothing when the distance is smaller than
the threshold it wants to use.
* lisp/emacs-lisp/track-changes.el: Prepare header for ELPA.
(track-changes--tracker, track-changes--state): Don't use `:noinline`,
so as to be compatible with Emacs<27.
(track-changes-record-errors): New variable.
(track-changes--recover-from-error): Use it. Record only the last 20
keys and the last 50 stack frames in the error log.
(track-changes--disjoint-threshold): Delete variable.
(track-changes--before): Don't use it any more.
* lisp/progmodes/eglot.el (eglot--track-changes-signal):
Coalesce disjoint changes nearer than what used to be coalesced because of
`track-changes--disjoint-threshold`.
Until now `cl-defstruct` signaled an error when encountering an
unknown option. It's easy to code and it does the job, but it
doesn't give good location info in the compiler's output,
and it makes it more painful to use not-yet-supported options.
So just signal a warning instead.
* lisp/emacs-lisp/cl-macs.el (cl-defstruct): Warn about unknown
options, instead of signaling an error.
* doc/lispref/peg.texi: Make more use of defmac/defmacro, and try to
clarify the relationships between the various macros and functions.
* lisp/progmodes/peg.el (peg-parse): Remove claim that PEXS can also be
a single list of rules.
* lisp/tab-line.el (tab-line-select-tab-buffer): Optimize.
(tab-line-switch-cycling): Enable by default like in tab-bar-mode.
(tab-line-switch-to-prev-tab, tab-line-switch-to-next-tab):
Add a prefix argument ARG and support it for switching tabs.
Improve docstring.
* doc/lispref/peg.texi: Make more use of defmac/defmacro, and try to
clarify the relationships between the various macros and functions.
* lisp/progmodes/peg.el (peg-parse): Remove claim that PEXS can also be
a single list of rules.
* lisp/emacs-lisp/track-changes.el (track-changes--before):
Widen the buffer before accessing it with positions
potentially outside the beg..end region.
* src/window.c (grow_mini_window, shrink_mini_window): Reimplement
how the frame's 'frozen_window_starts' flag is set and reset, to
make sure it is always reset when the mini-window gets to its
normal one-line height. Patch by Martin Rudalics
<rudalics@gmx.at> (Bug#70038)
* lisp/info.el (Info--dont-hide-references): New variable.
(Info-fontify-node): Use 'Info--dont-hide-references' to disable
hiding "*Note" or showing "See" instead of it in select nodes.
(Bug#70382)
* doc/emacs/android.texi (Android Environment): Rewrite several
paragraphs to better reflect recent changes and emphasize
behavior on modern OS releases.
* src/xdisp.c (note_fringe_highlight): Don't proceed if
popup_activated, window is outdated, or when row beneath pointer
does not display text. (bug#70385)
Bug reported and fix proposed by Aris Spathis.
* src/sort.c (merge_markmem): Mark heap-allocated temporary key values.
(tim_sort): Delay key function calls to after marking function has been
registered.
* test/src/fns-tests.el (fns-tests-sort-gc): New test.
* lisp/emacs-lisp/lisp.el (forward-sexp-default-function):
New function with body from 'forward-sexp' (bug#68993).
(forward-sexp-function): Change the default value from nil to
'forward-sexp-default-function'.
(forward-sexp): Use either 'forward-sexp-function' or
'forward-sexp-default-function'.
* lisp/treesit.el (treesit-forward-sexp): In nodes of type 'text'
fall back to 'forward-sexp-default-function'. Improve docstring.
* doc/lispref/positions.texi (List Motion): Fix pxref.
The command 'list-keyboard-macros' allows editing and re-arranging
macros using 'tabulated-list-mode'. Existing keyboard macros can be
duplicated or deleted. Macro counters and counter formats can take new
values read from the minibuffer. Macro keys can be edited using
'edit-kbd-macro'.
* doc/emacs/kmacro.texi (Kmacro Menu): Document the new command
and the menu's commands.
* etc/NEWS (Kmacro Menu Mode): Mention the new mode and command.
* lisp/kmacro.el (kmacro-menu-mark, kmacro-menu-marked)
(kmacro-menu-flagged): Add faces for marks and flags.
* lisp/kmacro.el (kmacro-menu-mode-map, kmacro-menu-mode): Add mode
and map.
* lisp/kmacro.el (list-keyboard-macros, kmacro-menu): Add command.
* lisp/kmacro.el (kmacro-menu--deletion-flags, kmacro-menu--marks)
(kmacro-menu--id-kmacro, kmacro-menu--id-position, kmacro-menu--kmacros)
(kmacro-menu--refresh, kmacro-menu--map-ids, kmacro-menu--replace-all)
(kmacro-menu--replace-at, kmacro-menu--query-revert, kmacro-menu--assert-row)
(kmacro-menu--propertize-keys, kmacro-menu--do-region)
(kmacro-menu--marks-exist-p): Add utility functions of mode
and commands.
* lisp/kmacro.el (kmacro-menu-mark, kmacro-menu-flag-for-deletion)
(kmacro-menu-unmark, kmacro-menu-unmark-backward)
(kmacro-menu-unmark-all): Add commands for marks and flags.
* lisp/kmacro.el (kmacro-menu-do-flagged-delete, kmacro-menu-do-copy)
(kmacro-menu-do-delete): Add commands that modify the ring.
* lisp/kmacro.el (kmacro-menu-edit-position, kmacro-menu-transpose)
(kmacro-menu-edit-format, kmacro-menu-edit-counter)
(kmacro-menu-edit-keys, kmacro-menu-edit-column): Add commands that
modify a keyboard macro.
This fixes bug#70367.
* lisp/progmodes/cc-mode.el (c-fl-decl-start): After searching
backwards for the end of the previous statement, check whether
or not we found it.
* lisp/textmodes/reftex-cite.el (reftex-all-used-citation-keys):
Match the citation keys used with multicite macros provided by
biblatex. (bug#38249)
* test/lisp/textmodes/reftex-tests.el
(reftex-all-used-citation-keys): Adjust test accordingly.
* lisp/progmodes/peg.el (peg-parse): Refine heuristic since unknown
terminals are resolved at run-time rather than compile-time now.
(peg--macroexpand) <stack-action>: Avoid generating a `let` with an
empty body.
(peg--translate-rule-body): Adjust to name change of
`macroexp-warn-and-return` and the fact that it's always available.
* test/lisp/progmodes/peg-tests.el (peg-parse-string):
Add `indent` declaration.
(peg-test): Check that the compiler emits the warnings we expect.
When `define-globalized-minor-mode` was introduced (Emacs-22),
`run-mode-hooks` was brand new, so we could not expect all major
modes to use it and we had to rely on brittle workarounds to try
and approximate `after-change-major-mode-hook`.
These workarounds have undesirable side effects, and (we hope)
they're not needed any more now that virtually all major modes
have been changed to use `run-mode-hooks` (or
`define-derived-mode`).
* lisp/emacs-lisp/easy-mmode.el (define-globalized-minor-mode):
Rely only on `after-change-major-mode-hook`, remove the "cmhh"
[typo for the intended "cmmh", BTW] workaround.
* doc/lispref/modes.texi (Mode Hooks): Clarify the importance of
`after-change-major-mode-hook` w.r.t `define-globalized-minor-mode`.
(Defining Minor Modes): Rewrite the explanation of which buffers
are affected, including adjusting it to the fact that
`fundamental-mode` has used run `run-mode-hooks` for last 10 years.
* lisp/emacs-lisp/easy-mmode.el (define-globalized-minor-mode) <MODE-cmhh>:
Try and detect well-behaved modes so they're not affected by
those which require the cmhh hack.
This new package provides an API that is easier to use right than
our `*-change-functions` hooks.
The patch includes changes to `diff-mode.el` and `eglot.el` to
make use of this new package.
* lisp/emacs-lisp/track-changes.el: New file.
* test/lisp/emacs-lisp/track-changes-tests.el: New file.
* doc/lispref/text.texi (Tracking changes): New subsection.
* lisp/progmodes/eglot.el: Require `track-changes`.
(eglot--virtual-pos-to-lsp-position): New function.
(eglot--track-changes): New var.
(eglot--managed-mode): Use `track-changes-register` i.s.o
`after/before-change-functions` when available.
(eglot--track-changes-signal): New function, partly extracted from
`eglot--after-change`.
(eglot--after-change): Use it.
(eglot--track-changes-fetch): New function.
(eglot--signal-textDocument/didChange): Use it.
* lisp/vc/diff-mode.el: Require `track-changes`.
Also require `easy-mmode` before the `eval-when-compile`s.
(diff-unhandled-changes): Delete variable.
(diff-after-change-function): Delete function.
(diff--track-changes-function): Rename from `diff-post-command-hook`
and adjust to new calling convention.
(diff--track-changes): New variable.
(diff--track-changes-signal): New function.
(diff-mode, diff-minor-mode): Use it with `track-changes-register`.
* lisp/progmodes/compile.el
(compilation--insert-abbreviated-line): Handle long lines that end
in a newline. (Bug#70236)
The fix in commit 8f93cba324 resulted in
the previous "Don't hide the final newline" code causing an off-by-one
error. With the new code the value of point is what is wanted in both
cases.
* src/image.c (free_image):
* src/xfaces.c (free_realized_face): Handle scenarios where
free_frame_faces is called with the display connection cut.
* src/xterm.c (x_free_frame_resources): Call free_frame_faces
unconditionally, lest fontsets for this dead frame contaminate
Vfontset_list and produce crashes afterwards. (bug#66151)
