* src/term.c (handle_one_term_event): Don’t access possibly
uninitialized storage if frame is nil. This fixes an issue introduced
in commit 5eae7f5227 dated 2025-01-26
14:43:51 -0800. Issue caught by --enable-gcc-warnings, which enables
-Wanalyzer-use-of-uninitialized-value with gcc (GCC) 14.2.1 20250110
(Red Hat 14.2.1-7).
* test/lisp/emacs-lisp/bytecomp-tests.el:
(bytecomp-tests--dest-mountpoint): Skip test if bwrap prohibits
even ‘true’, which it does on my Ubuntu 24.10 platform.
* lisp/progmodes/eglot.el (eglot-menu): Add separator at end
and add in eglot-server menu at load-time.
(eglot-server-menu): Rework menu title and description.
* lisp/window.el (replace-buffer-in-windows): Preserve current
buffer when 'kill-buffer-quit-windows' is non-nil and a window
showing BUFFER shall be quit. Running 'kill-buffer-hook' relies
on it (Bug#75949).
* lisp/tab-bar.el (tab-bar--format-tab):
Add new variable 'tab-bar-format-tab-help-text-function' and a default
function 'tab-bar-format-tab-help-text-default'. 'tab-bar--format-tab'
respects this new variable when producing a tab's help text, normally
shown in the echo area or via tooltips (bug#75950).
* lisp/treesit.el:
(treesit-add-simple-indent-rules): New function.
* etc/NEWS: Update NEWS.
*
test/src/treesit-tests.el:
(treesit-test-add-simple-indent-rules): Add a test for the new
function.
Remove the nil-check conditionals around 'wc-bl' and 'wc-bbl' that reset
frame parameters 'buffer-list' and 'buried-buffer-list'. This ensures
originating nil values correctly propagate (bug#75935).
* lisp/tab-bar.el (tab-bar-define-keys):
Add new defcustom tab-bar-define-keys. Reorganize key binding functions
to accommodate. Also remove checks for tab-bar-mode enabled in
'tab-bar-select-tab-modifiers', as unnecessary and which prevented user
changes from being accepted in cases where the user defers enabling
tab-bar-mode (bug#75918).
* doc/misc/tramp.texi (Predefined connection information):
Mention also "androidsu" as special case of "tmpdir".
(Remote processes): Signals are not delivered to remote direct
async processes. Say, that there are restrictions for transfer of
binary data to remote direct async processes.
* lisp/net/tramp-compat.el (tramp-compat-temporary-file-directory):
Simplify.
* src/treesit.c (resolve_language_symbol): Move forward.
(treesit_ensure_query_compiled): Resolve language remapping
here.
(Ftreesit_parser_list): Don't resolve language remaping here,
because there's no need: parsers now carries the remapped
language.
(Ftreesit_query_compile): Don't resolve language remapping here,
because we resolve language remapping when actually compiling
the query. Also we want the query to carry the unmapped
language.
treesit-declare-unavailable-functions is not available for old
emacs versions, but python.el is a core package available on
ELPA.
Remove the treesit-declare-unavailable-functions until compat.el
releases a new version that contains it.
* lisp/progmodes/python.el: Remove
treesit-declare-unavailable-functions and add back
declare-function forms.
* src/dispnew.c (write_matrix): Don't set the cursor here. Parameter to
set the cursor or not removed.
(combine_updates_for_frame): Call tty_set_cursor here, depending on
whether or not the selected frame is related to the updated frame.
(update_frame_with_menu): Adapt to change of write_matrix.
* src/dispnew.c (WINDOW_TO_FRAME_VPOS, WINDOW_TO_FRAME_VPOS): Macros
removed.
(window_to_frame_vpos, window_to_frame_vpos): Always define, and use
them instead of the removed macros.
Parentheses in macros were getting incorrectly propertized with
the '(1) (punctuation) syntax-table text property. This was
due to a typo in the patch "CC Mode: Rationalize and optimize
cache invalidation (1)" from 2024-10-06. Correct this.
* lisp/progmodes/cc-mode.el (c-depropertize-CPP): Move the
first c-clear-syntax-table-with-value-trim-caches invocation
from inside the enclosing `when' form to after it.
When eglot-autoshutdown is t and the only reason we're
considering it is because of a revert (which tears down Eglot's
minor mode as if by killing), detect that situation and
purposedly cancel the shutdown.
* lisp/progmodes/eglot.el (eglot--managed-mode): Tweak.
Didn't know it was possible, thanks to Ergus <spacibba@aol.com> for the
tip about binding [left-margin mouse-2] in the keymap.
The technique adopted in 'eglot-mouse-call' possibly still doesn't work
very well if the margin thing we're clicking on is not on the line point
is currently on. But we don't have that problem (yet?) because LSP
action suggestions function mostly on a "at point" basis.
* lisp/progmodes/eglot.el (eglot-code-action-indications): Adjust docstring.
(eglot--mouse-call): Don't go anywhere except in text area.
(eglot-diagnostics-map): Bind eglot-mouse-actions to left-margin.
* lisp/progmodes/hideshow.el (hs-inside-comment-p-func):
New buffer-local variable.
(hs-hide-block-at-point): Check if 'hs-block-end-regexp' is
a string or a function.
(hs-inside-comment-p): Move body to 'hs-inside-comment-p--default'.
Call 'hs-inside-comment-p-func' if it's a function.
(hs-inside-comment-p--default): New function with body from
'hs-inside-comment-p'.
(hs-hide-all): Don't use 'hs-block-start-regexp' when it's not a string.
(hs-minor-mode): Don't call 'hs-grok-mode-type' when
'hs-inside-comment-p-func' already has a buffer-local value.
* lisp/treesit.el (treesit-hs-block-end)
(treesit-hs-find-block-beginning, treesit-hs-find-next-block)
(treesit-hs-looking-at-block-start-p)
(treesit-hs-inside-comment-p): New functions.
(treesit-major-mode-setup): Set hs-minor-mode buffer-local variables.
* src/frame.c (make_frame): Handle 'expose-hidden-buffer'.
(expose-hidden-buffer): New variable to handle hidden buffers.
* src/buffer.c (Fother_buffer): Mention that it does not return
a hidden buffer.
* lisp/frame.el (make-frame): In doc-string describe handling
of hidden buffers.
* doc/lispref/frames.texi (Creating Frames): Explain handling
of hidden buffers in description of 'make-frame'.
Setting this variable to true causes Eglot to send special
cancellation notification for certain stale client request.
This may help some LSP servers avoid doing costly but ultimately useless
work on behalf of the client, improving overall performance.
Request cancellation is described in
https://microsoft.github.io/language-server-protocol/
specifications/lsp/3.17/specification/#cancelRequest
* lisp/jsonrpc.el (jsonrpc-request): Accept function as value for
CANCEL-ON-INPUT.
* lisp/progmodes/eglot.el (eglot--request): Rework.
* doc/misc/eglot.texi (Customizing Eglot): Mention
eglot-advertise-cancellation.
* doc/misc/eglot.texi (Starting Eglot): Tweak.
(Using Eglot): Remove link to 'Eglot Variables'.
(Eglot Features): Rework.
(Eglot and Buffers): Rework.
(Eglot Commands): Rework.
(Customizing Eglot): New chapter.
(Customization Variables): Now contains what 'Eglot Variables'
used to contain.
(Other Variables): New section.
(More Customization): New section.
(...elsewhere...): Apply 'fill-paragraph'.
Even though highlighting the thing at point isn't really producing
documentation at point, theory and practice have shown that using
eldoc-documentation-functions for this is a feasible way to avoid
reimplementing all the idle timer logic for such functionality.
In fact, we were already using ElDoc for this purpose, but this commit
makes it so the new eglot-highlight-eldoc-function is a first class
citizen in eldoc-documentation-functions, so users can manipulate it if
so desired.
* lisp/progmodes/eglot.el (eglot--managed-mode): Use
eglot-highlight-eldoc-function
(eglot-hover-eldoc-function): Don't mix highlighting with hover.
(eglot-highlight-eldoc-function): Rename and rework from
eglot--highlight-piggyback
* src/xdisp.c (vmessage): Avoid undefined behavior if
FRAME_MESSAGE_BUF_SIZE (f) is zero, or if doprnt generates output
containing only encoding errors. Although it’s not clear whether
either is possible, it is better to be safe. Also, clarify via a
new local message_bufsize.
* src/xdisp.c (vmessage): Increase buffer size to fit an extra
multibyte character. On buffer overflow, drop the last multibyte
character to determine an accurate byte length.
