'python-shell-get-process' is frequently called from
'python-eldoc--get-doc-at-point' and etc., invoking
'project-current' unless there is a buffer-specific Inferior
Python process. When the buffer is a remote buffer not
belonging to any project and has significant latency,
'project-current' may take a long time. To avoid this,
implement a process cache in 'python-shell-get-process'.
* lisp/progmodes/python.el (python-shell--process-cache)
(python-shell--process-cache-valid): New variables.
(python-shell--invalidate-process-cache): New function.
(python-shell-make-comint): Add a call to the above function.
(python-shell-get-process): Add process cache. (Bug#80045)
Previously, both the definition of __PYTHON_EL_get_completions
and the call to __PYTHON_EL_get_completions were sent to the
inferior Python each time
'python-shell-completion-get-completions' was executed.
However, there is no need to send the definition every time as
long as the definition remains unchanged. We improved this so
that the definition of __PYTHON_EL_get_completions is only sent
during the inferior Python initialization; it is no longer sent
during 'python-shell-completion-get-completions' execution.
* lisp/progmodes/python.el
(python-shell-completion-send-setup-code): New function.
(python-shell-first-prompt-hook): Add the above new function.
(python-shell-completion-get-completions): Omit sending
'python-shell-completion-setup-code'. (Bug#80182)
With higher values of 'calc-string-maximum-character', rules
made up of glyphs of non-unit width can be the wrong length.
Calculate the number of characters in the rule based on the
display width, rounded up to the nearest integer. Refines
feature introduced in bug#78528.
* lisp/calc/calccomp.el (math-comp-simplify-term): Calculate
rule width with a ratio of 'string-pixel-width's.
With higher values of 'calc-string-maximum-character' the
string length can differ from the displayed width. Calculate
alignment offsets based on the the display width, rounded up to
the nearest integer. Refines feature introduced in bug#78528.
* lisp/calc/calccomp.el (math-comp-width): Replace 'length' with
a ratio of 'string-pixel-width's.
Previously, if 'calc-string-maximum-character' wasn't a valid
character 'math-vector-is-string' would throw an error in the
comparison, leading to an incomplete display of the stack and a
cryptic error message. Instead, have 'math-vector-is-string'
return nil, which effectively disables the display of strings.
Refines feature introduced in bug#78528.
* doc/misc/calc.texi (Customizing Calc): Update description of
behavior for invalid 'calc-string-maximum-character'.
* lisp/calc/calccomp.el (math-vector-is-string): Return nil when
'calc-string-maximum-character' doesn't represent a character.
* test/lisp/calc/calc-tests.el (calc-math-vector-is-string): Correct
and simplify tests.
* lisp/textmodes/text-mode.el (center-line-mode--track-changes):
New local variable for storing the id of the change tracker registered
for the current buffer.
(center-line-mode--track-changes-signal): New function to be called by
the track-changes library whenever there is a change in the current
buffer.
(center-line-mode--track-changes-function): New function called from the
above signal function, iterates over the lines of the modified region,
calling 'center-line' for each non-empty line.
(center-line-mode): New minor mode.
* etc/NEWS: Document the new minor mode.
* etc/NEWS:
* doc/emacs/maintaining.texi (Projects):
* lisp/progmodes/project.el (project-mode-line): Update
documentation due to changes in bug#78545.
Add an optional 'context' argument to 'make-progress-reporter'
which 'progress-reporter-echo-area' consults to inhibit updates
if the context is 'async' and the echo area is busy.
* lisp/subr.el (make-progress-reporter): Add the optional
'context' argument.
(progress-reporter-context): New defun accessor.
(progress-reporter-echo-area): Consult
'progress-reporter-context'.
* doc/lispref/display.texi: Document context.
* etc/NEWS: Announce context.
* lisp/textmodes/ispell.el (ispell-save-corrections-as-abbrevs):
New user option.
(ispell--abbrev-saving-allowed)
(ispell--save-correction-as-abbrev): New variables.
(ispell--maybe-save-correction-abbrev): New function.
(ispell-word, ispell-process-line): Use them to save corrections
as abbrevs when appropriate (bug#79985).
(ispell-command-loop): Add C-u as command character to toggle
abbrev saving for an immediately following replacement command.
(ispell-help): Document C-u binding.
* doc/emacs/fixit.texi (Spelling): Document new feature.
(project-name-cache-timeout): New variable.
(project-name-cached): New function (bug#78545).
(project-mode-line): New value 'non-remote'.
(project-mode-line-format): Don't show the remote project's name
when 'project-mode-line' is 'non-remote'. Use 'project-name-cached'.
* lisp/term/xterm.el (xterm-update-cursor): Mention OSC 112 in
doc string.
(xterm--reset-cursor-color-escape-sequence): New constant.
(xterm--init-update-cursor, xterm--update-cursor-color): Use it
(bug#80091).
When a completion candidate has no suffix, then there is no need to
add whitespace "between" the candidate and suffix, since there is no
need to align suffixes if there are none. In this case the trailing
whitespace only serves to needlessly make all candidates the same
length, with the result that if one candidate does not fit one a
single line, then all other candidates are made to not fit either.
* lisp/emacs-lisp/package-activate.el: Move defvar of
`Info-directory-list` to when we know it should exist.
* lisp/emacs-lisp/package.el (Info-directory-list): Defvar before we
`let-bind it.
Now when calling 'Buffer-menu-unmark-all-buffers', only the
selected mark is removed.
* lisp/buff-menu.el (Buffer-menu--unmark): Add a mark parameter
to correctly select it in the entry.
(Buffer-menu-unmark, Buffer-menu-unmark-all-buffers)
(Buffer-menu-backup-unmark): Usage.
They're always called immediately before a `<` char, in which case
they do the same anyway. This saves us from having to touch
`forward-list-function` in addition to `forward-exp-function`.
While at it, change `sgml-tags-invisible` to use `define-minor-mode`.
* lisp/textmodes/sgml-mode.el (sgml-delete-tag)
(sgml-electric-tag-pair-before-change-function): Prefer `forward-sexp`
over `forward-list`.
(sgml-tags-invisible): Define with `define-minor-mode`. Don't disable
`cursor-sensor-mode` when we don't need it any more, since some other
package may be using it. Remove redundant binding of `inhibit-read-only`.
* lisp/emacs-lisp/lisp.el (forward-sexp-function): Give it a default value.
(forward-sexp): Simplify a bit.
(up-list-default-function): Fix for `forward-sexp-default-function`.
A unique frame id is assigned to a new or cloned frame, and
reused on an undeleted frame.
The id facilitates unambiguous identification among frames that
share identical names or titles, deleted frames where a live
frame object no longer exists that we can resurrect by id, for
example via 'tab-bar-undo-close-tab'. It also aids debugging at
the C level using the frame struct member id.
Rewrite 'clone-frame' and 'undelete-frame' to not let bind
variables that 'make-frame' uses to avoid conflicts with nested
'make-frame' calls, for example via
'after-make-frame-functions'.
* lisp/frame.el (clone-frame, undelete-frame): Use
'frame--purify-parameters' to supply parameters explicitly.
(undelete-frame--save-deleted-frame): Save frame id for
restoration.
(undelete-frame): Restore frame id.
(frame--purify-parameters): New defun.
(make-frame): Assign a new id for a new or cloned frame, reuse
for undeleted frame.
* src/frame.h (struct frame): Add id member.
(frame_next_id): New extern.
* src/frame.c (frame_next_id): New global counter.
(frame_set_id, frame_set_id_from_params): New function.
(Fframe_id): New DEFUN.
(syms_of_frame <Sframe_id>): New defsubr.
(syms_of_frame <Qinternal_id>): New DEFSYM.
(syms_of_frame <frame_internal_parameters>): Add 'Qinternal_id'.
* src/androidfns.c (Fx_create_frame):
* src/haikufns.c (Fx_create_frame):
* src/nsfns.m (Fx_create_frame):
* src/pgtkfns.c (Fx_create_frame):
* src/w32fns.c (Fx_create_frame):
* src/xfns.c (Fx_create_frame): Call 'frame_set_id_from_params'.
* doc/lispref/frames.texi: Add documentation.
* etc/NEWS: Announce frame id.
(html-ts-mode--show-paren-data): New function to exclude
unbalanced tags when the closing tag is missing.
(html-ts-mode): Set 'show-paren-data-function' to
'html-ts-mode--show-paren-data' (bug#80151).
(sgml-electric-tag-pair-before-change-function):
Let-bind 'forward-list-function' to nil.
(sgml-delete-tag): Let-bind 'forward-sexp-function'
and 'forward-list-function' to nil.
(sgml-tags-invisible): Let-bind 'forward-list-function' to nil.
All this is required to use the default definitions of sexp/list
that significantly differ from treesit definitions (bug#80151).
* lisp/emacs-lisp/cl-generic.el (cl--generic-make-function):
Preserve advertised-calling-convention info.
* test/lisp/emacs-lisp/pcase-tests.el (pcase-tests-quote-optimization):
Require `byte-opt` to fix the test when the compiler is not loaded yet.
* lisp/progmodes/elisp-mode.el: Fix some >80column problems.
(elisp--xref-format-extra)
(elisp--xref-format): Make them constant, now that we don't have
the purespace. Also, use %S since some of the elements
don't necessarily have names and even if they do, we'd want to
escape any funny characters in them to avoid ambiguities.
(elisp--xref-find-definitions): Fix uses of
`elisp--xref-format-extra` accordingly.
Improve heuristic to distinguish proper `cl-defgeneric` from
implicit ones.
(elisp-eldoc-docstring-length-limit)
(elisp-eldoc-funcall-with-docstring-length): Remove redundant `:group`.
* lisp/cedet/mode-local.el (xref-mode-local-overload): Pass the
override symbol rather than its name through `elisp--xref-format-extra`.
* test/lisp/progmodes/elisp-mode-tests.el (find-defs-constructor):
Adjust test to new text.
* lisp/faces.el (tab-bar, tab-line): Adapt to dark background.
Suggested by Philip Kaludercic <philipk@posteo.net>.
* lisp/tab-bar.el (tab-bar-tab, tab-bar-tab-inactive, tab-bar-tab-highlight):
* lisp/tab-line.el (tab-line-tab, tab-line-tab-inactive)
(tab-line-tab-current, tab-line-highlight): Adapt faces to dark background.
