* lisp/progmodes/eglot.el (eglot--format-server-message): New helper.
(eglot-handle-notification<window/showMessage>)
(eglot-handle-request<window/showMessageRequest>): Use it.
* lisp/progmodes/python.el (python-ts-mode):
Set 'treesit-sexp-thing-down-list' to 'list' to override
sexp navigation with list navigation (bug#72478).
* lisp/emacs-lisp/lisp.el (up-list): Mention 'up-list-function' in docstring.
* etc/NEWS: Announce the new customization option (bug#80215).
* lisp/textmodes/yaml-ts-mode.el (yaml-ts-mode): New customization group.
(yaml-ts-mode-yamllint-options): New customization option.
(yaml-ts-mode--flymake-process): New variable that stores the reference
to the flymake process.
(yaml-ts-mode-flymake): New function that implements support for Flymake.
* lisp/progmodes/json-ts-mode.el (json-ts--get-path-at-node)
(json-ts--path-to-jq, json-ts--path-to-python): New functions.
(json-ts-jq-path-at-point): New command for getting JSON path at point.
* test/lisp/progmodes/json-ts-mode-tests.el: New file.
Add tests for the utility command.
* etc/NEWS: Announce new command 'json-ts-jq-path-at-point' (bug#80190).
The doc string of 'frame-or-buffer-changed-p' says not to call it
with the nil argument, but term.el did. Since "M-x term" puts
'term--update-term-menu' on the 'menu-bar-update-hook' ahead of
'menu-bar-update-buffers', it caused the latter decide that there
was no change in buffers, because the internal state variable
used by 'frame-or-buffer-changed-p' when called with the nil
argument was reset by 'term--update-term-menu'. Fix that by using
a non-nil state variable.
* lisp/term.el (term--buffers-changed): New variable.
(term--update-term-menu): Use it when calling
'frame-or-buffer-changed-p'. (Bug#80231)
Some language servers request file watching for a very large number of
directories (e.g. Python virtualenvs), which can exhaust system
resources and cause slow startup.
https://github.com/joaotavora/eglot/issues/1568
* lisp/progmodes/eglot.el (eglot-max-file-watches): New variable.
(eglot--count-file-watches): New function.
(eglot--watch-globs): Use them to limit watches. Signal jsonrpc-error
when limit is reached.
(eglot-watch-files-outside-project-root): Fix docstring punctuation.
* etc/EGLOT-NEWS: Mention change.
Now also accepts file operation kinds as keys in the alist form.
* lisp/progmodes/eglot.el (eglot-confirm-server-edits): Rework
default value, docstring and defcustom type.
(eglot--confirm-server-edits): Also check for operation-kind-based
entries.
The current 2026 landscape suggests servers (especially gopls
and ocamllsp) take advantage of this, so let's give it to them
by default.
* lisp/progmodes/eglot.el (eglot-advertise-cancellation):
Default to t.
* etc/EGLOT-NEWS: Mention change.
If the user simply C-g's signal a 'jsonrpc-error' with code 32000 to
mean "no error", provide an LSP :failureReason and keep server chill.
* lisp/progmodes/eglot.el (eglot-handle-request<workspace/applyEdit>>):
Else, if the server asks us a question, the user has just 10
seconds to ponder, which is a bit silly.
* lisp/progmodes/eglot.el (eglot-execute): Pass timeout=nil to
eglot--request.
Previously, the default answer pre-filled in the minibuffer was
obscuring the other possible answers.
* lisp/progmodes/eglot.el
(eglot-handle-request<window/showMessageRequest>): Rework.
It was completely broken, with a cancel being set for every sent (and
probably already received) async request, and no actual discarding
of the response of a cancelled request.
* lisp/progmodes/eglot.el (eglot--async-request): Fix cancellation
of async requests.
(eglot--semtok-request): Don't need 'buf' &aux anymore.
Previously, 'quit' could cause remote endpoints to never get a
reply and thus sometimes hang. Ensure we always reply. Also,
give the application a chance to signal jsonrpc-error with the
served code=32000, meaning "no error".
* doc/lispref/text.texi (JSONRPC Overview): Rework section on
request dispatchers.
* lisp/jsonrpc.el (jsonrpc-connection-receive): Rework.
This allows clients such as Eglot to act on the user
C-g's/quits out of a blocking jsonrpc-request call. It also
fixes the TIMEOUT=nil passed to jsonrpc-request. An infinite
timeout in that case (for a long-running request, for example)
and it was not being transmitted to the lower
jsonrpc-async-request.
* lisp/jsonrpc.el (jsonrpc-request): Add CANCEL-ON-QUIT. Rework
docstring.
* lisp/window.el (quit-restore-window): Try to restore the
previously selected window only if WINDOW is either the selected
window or BURY-OR-KILL is neither 'burying' nor 'killing'.
Otherwise, this might deliberately change the selected window,
for example, when 'kill-buffer-quit-windows' is non-nil and WINDOW
shows the buffer to kill.
Using 'user-error' in 'hs-minor-mode', prevents the major-mode
from initializing correctly when hideshow is not supported in
that mode, using 'message' instead fixes this.
* lisp/progmodes/hideshow.el (hs-minor-mode): Tweak.
In async mode, the workaround for the old Terminal.app collides
with the binding we install for the primary DA. Just drop it.
* lisp/term/xterm.el (xterm--init): Remove workaround for very old
macOS `Terminal.app`.
The info returned from `garbage-collect` is really handy to
track the evolution of the heap size, but sadly it's available only
at the cost of running a full GC, which has two big downsides:
it's slow, it affects what we're measuring, and it can't be used
in `post-gc-hook`.
So, this patch makes it available without running the GC.
* src/alloc.c (Fgarbage_collect_heapsize): New function, extracted from
`Fgarbage_collect`.
(Fgarbage_collect): Use it.
(syms_of_alloc): defsubr it.
* doc/lispref/internals.texi (Garbage Collection): Extract
documentation for it from that of `garbage-collect`.
This is in order to apply `browse-url-transform-alist'.
* lisp/net/browse-url.el (browse-url-with-browser-kind)
(browse-url-button-open, browse-url-button-open-url):
* lisp/net/shr.el (shr-browse-url):
* lisp/net/eww.el (eww-browse-with-external-browser):
* lisp/gnus/gnus-sum.el (gnus-summary-browse-url):
* lisp/emacs-lisp/package.el (package-browse-url): Let-bind
`browse-url-browser-function' and call `browse-url'.
* src/pdumper.c (pdumper_set_emacs_execdir):
Don’t use basename; simply use the pointer we already have.
If we ever need a basename-like function in the future, we should
use Gnulib’s basename-lgpl module, as POSIX basename modifies its
argument string and is incompatible with glibc/Android basename; see
<https://www.gnu.org/software/gnulib/manual/html_node/basename.html>.
* configure.ac: If --enable-gcc-warnings, don’t use
-Wzero-as-null-pointer-constant, which is enabled by default with
bleeding-edge Gnulib (as there seems to be movement in this
direction in C2y). Although -Wzero-as-null-pointer-constant is
useful, Emacs isn’t clean for it yet.
* lisp/simple.el (goto-line, goto-line-relative): Add new arg 'interactive'.
Remove 'declare' with 'interactive-only'. Don't push the mark when called
non-interactively.
* src/nsterm.m (ns_select_1): Return thread_select if current
thread is not the main thread or timeout is zero; otherwise call
'thread_select' with a minimal timeout to allow other Lisp
threads to run. (Bug#80110, Bug#80112)
* lisp/net/tramp-adb.el:
* lisp/net/tramp-androidsu.el:
* lisp/net/tramp-integration.el:
* lisp/net/tramp-smb.el: Do not delay
`connection-local-set-profiles' until after loading `shell'.
* lisp/net/tramp-integration.el: Add the local profile for all
hosts listed in `tramp-local-host-names'.
* lisp/net/tramp.el (tramp-local-host-names): New defvar.
(tramp-local-host-regexp): Use it.
* test/lisp/net/tramp-tests.el (tramp-test03-file-name-defaults):
Adapt test.
