This new derived mode is intended for consumers that render
Markdown content for display rather than editing, such as Eglot
and Eldoc when showing documentation popups and buffers. It
pre-sets the relevant customizations (markup hidden, inline
images on, hard-line-break markup hidden, native code-block
fontification, table and code-block context minor modes off),
makes the buffer read-only, and uses its own keymap derived from
'special-mode-map' so navigation keys behave like a viewer.
A pre-init hook lets callers normalize buffer content before the
grammar parses it; 'markdown-ts-add-final-newline' is the
default so that markup depending on a terminating newline parses
correctly. 'markdown-ts-buffer-string' returns the rendered
buffer string with overlay faces flattened into text properties,
which is useful for callers that capture the rendered output.
Along the way: 'list_marker_parenthesis' is now recognized as an
ordered list marker; the strikethrough query is simplified to a
single rule; thematic breaks span the window via an ':extend'
underline when the face supports it.
* lisp/textmodes/markdown-ts-mode.el (markdown-ts-view-mode):
New read-only derived mode.
(markdown-ts-view-mode-map): New keymap.
(markdown-ts-view-mode-pre-init-hook): New hook, defaulting to
'markdown-ts-add-final-newline'.
(markdown-ts-mode--initialize): New helper, factored out of
'markdown-ts-mode' so 'markdown-ts-view-mode' can reuse the
parser readiness and setup logic after overriding local
variables.
(markdown-ts-mode): Call 'markdown-ts-mode--initialize'.
(markdown-ts-add-final-newline): New function.
(markdown-ts-buffer-string): New function.
(markdown-ts-unordered-list-marker): New defcustom.
(markdown-ts-hard-line-break-backslash)
(markdown-ts-hard-line-break-space): Accept the symbol 'hide.
(markdown-ts--fontify-hard-line-break): Honor 'hide.
(markdown-ts--fontify-atx-heading)
(markdown-ts--fontify-setext-heading)
(markdown-ts--fontify-atx-delimiter)
(markdown-ts--fontify-unordered-list-marker)
(markdown-ts--list-item-depth): New functions supporting clean
rendering when markup is hidden.
(markdown-ts--fontify-thematic-break): Use ':extend' underline
span when the face supports it.
(markdown-ts--resolve-display-value): Accept non-cons values.
(markdown-ts--list-ordered-item-p): Also recognize
'list_marker_parenthesis'.
(markdown-ts--range-settings): Mark markdown-inline embed as
':local t'.
(markdown-ts--set-up): Create the markdown-inline parser only in
the inline setup branch; drop the redundant
'markdown-ts-hide-markup' make-local-variable.
(markdown-ts--treesit-settings): Route atx and setext headings
to their dedicated fontifiers; route unordered list markers
through 'markdown-ts--fontify-unordered-list-marker'; move
'strikethrough' to the simpler paragraph-inline query.
* lisp/textmodes/markdown-ts-mode.el
(markdown-ts--treesit-settings): Add a new font-lock block for
'paragraph-inline' that handles strikethrough nodes more
carefully.
* lisp/textmodes/markdown-ts-mode.el
(markdown-ts--treesit-settings): Move the 'code_span' and
'code_span_delimiter' font-lock rules into a separate block with
':override prepend' instead of 'append'. The heading feature
(level 1) applies its face via 'font-lock-append-text-property',
so a code span that later appends 'markdown-ts-code-span' ends
up with '(markdown-ts-heading-N markdown-ts-code-span)', where
the heading face takes priority and the code-span face is
suppressed. Prepending ensures 'markdown-ts-code-span' appears
first in the face list and wins visually.
* lisp/textmodes/markdown-ts-mode.el (markdown-ts-inline-images):
Now buffer local.
(markdown-ts--fontify-image): Defensively test for graphical
display before rendering images.
Since Emacs-27, `package-initialize` is for internal use only,
and callers should either call `package-activate-all` instead
(cheaper and faster) or do nothing at all (because the other
functions should trigger the needed initialization automatically
as needed).
* doc/lispref/package.texi (Packaging Basics): Delete `package-initialize`.
* doc/misc/eglot.texi (Reporting bugs): Don't recommend using `package-initialize`.
* doc/misc/org.org (Using Emacs packaging system): Simplify the command
line since both `(require 'package)` and `(package-initialize)` are
redundant here.
* lisp/vc/vc-dir.el (vc-dir-recompute-file-state): Delete
recently introduced TRUENAME parameter.
(vc-dir-resynch-file): Pass the file name from before calling
file-truename to vc-dir-recompute-file-state.
* doc/misc/erc.texi: Change ERCVER to 5.6.2.31.1.
* lisp/erc/erc.el: Change "Version" package header to 5.6.2.31.1. Don't
update the `customize-package-emacs-version-alist' entry because this is
not a GNU ELPA release.
(erc-version): Change version to 5.6.2.31.1.
Do not merge to master.
* lisp/textmodes/sgml-mode.el (sgml--find-<>-backward): Ignore
SGML tags that happen to occur within comments. This also means
that the contents of comments are not indented, but also do not
affect the indentation of tags following the comments as well.
(Bug#80841)
* lisp/net/eww.el (eww-submit): If a form does not specify an action
the assumed action is the current URL. If the current URL has an
existing query part, that part must be replaced by the form values,
rather than appended to.
Copyright-paperwork-exempt: yes
* lisp/minibuffer.el (completions--start-background-update):
Cancel a possible leftover timer (e.g. from the previous
after-change hook) that would suppress the display of
*Completions* when 'completion-eager-update' is nil.
(completions--after-change): Don't start background update
when not required to automatically update *Completions*.
* lisp/startup.el (prepare-user-lisp): Call
'directory-files-recursively' with a non-nil value for
FOLLOW-SYMLINKS. This was the intended way for the function to
operate, during the planning phase, so that users could
structure their User Lisp directory by linking in Lisp
directories from other parts of their file system.
* src/xterm.c (handle_one_xevent): Move the
x_clear_under_internal_border call before expose_frame, for less
chance of implicit flush to screen in between (bug#80662).
Calls to 'read-passwd' may be nested. The old code didn't handle
that, because some of the state was global and we'd end up revealing
passwords. The new code still has global state, but it has been
changed so that we hide rather than reveal passwords when we enter or
leave a nested read-passwd prompt.
* lisp/auth-source.el (read-passwd--hide-password): Removed.
(read-passwd--password-hidden): New.
(read-passwd-toggle-visibility): Add optional FORCE argument.
(read-passwd--mini-buffers): New variable.
(read-passwd-mode): Don't modify mode line when nested. Hide password
when returning to nested minibuffer or entering a new one.
This functionality has been replaced by the new sleep library
which supports more then just DBUS systems.
* lisp/obsolete/gnus-dbus.el: Add Obsolete-since header. Add
commentary.
(gnus-dbus-close-on-sleep, gnus-dbus-sleep-registration-object)
(gnus-dbus-register-sleep-signal gnus-dbus-sleep-handler)
(gnus-dbus-unregister-sleep-signal): Mark as obsolete.
Previously, "M-x rmail" would not call 'run-mode-hooks', which
didn't let globalized minor modes a chance to turn on themselves
in Rmail buffers. This modifies the way Rmail runs the various
hooks so as to abide by behavior required by Emacs 30 and later.
* lisp/mail/rmail.el (rmail-mode-2): Call 'run-mode-hooks'.
(rmail-mode): Call 'run-hooks', not 'run-mode-hooks'. Suggested
by Mark Lillibridge <mdl@alum.mit.edu>. (Bug#80879)

When the server negotiates positionEncoding utf-8 or utf-16,
ParameterInformation.label vector offsets are byte/code-unit counts
into the signature label, not character counts. Using them raw caused
wrong highlights and crashes on Unicode-rich signatures.
* lisp/progmodes/eglot.el (eglot--sig-info): Mostly rewrite.
(eglot-move-to-utf-8-linepos-function): Tweak docstring.
(eglot-move-to-utf-8-linepos, eglot-move-to-utf-16-linepos): Return
position moved to.
Improve the usability of treesit-explore-mode.
- Prompt for the primary parser first, if there is one, rather
than the first in the list reported by 'treesit-parser-list'.
Previously, in a multi-parser buffer like 'markdown-ts-mode', one
had to hunt for the primary parser.
- Kill the tree buffer and its window if the source buffer is
killed or 'treesit-explore-mode'. Previously, when
'treesit-explore-mode' is disabled in the source buffer, its
companion explorer tree buffer was left dangling and window
open (with an unrelated buffer).
- Improve 'treesit--explorer-refresh-1' to recenter the window
around the selected nodes when the selected region in the source
buffer changes. Previously, one had to navigate manually to find
the corresponding highlighted node in the tree window which may
be far away from that the source buffer's region represents.
- Disable 'treesit-explore-mode' in the source buffer if its
companion tree buffer is killed. Previously,
'treesit-explore-mode' remained active in the source buffer in
an effectively unusable state.
- Disable 'treesit-explore-mode' if the user quits
'completing-read' in 'treesit-explorer-switch-parser' when
enabling the mode. Previously, 'treesit-explore-mode' was left
enabled after quit.
- New command to switch back and forth between the source buffer
and tree buffer windows to make navigating more convenient.
Previously, in a multi-window frame, one had to navigate to/from
these two related windows in a more cumbersome way.
- New command to quit 'treesit-explore-mode' and
'treesit--explorer-tree-mode' and handle buffer and window
cleanup.
* lisp/treesit.el (treesit--explorer-refresh-1): Recenter the
window, if amenable, to the node selected in the source buffer.
(treesit--explorer-kill-explorer-buffer): Remove function.
(treesit--explorer-generate-parser-alist): Prioritize the
primary parser, if there is one.
(treesit--explorer-tree-mode-cleanup): New defun.
(treesit-explore-quit): New command.
(treesit-explorer-tree-window): New defun.
(treesit-explorer-source-buffer-window): New defun.
(treesit-explore-mode-map): Revise key bindings.
(treesit--explorer-tree-mode-map): Revise key bindings.
(treesit--explorer-tree-mode): New keymap.
(treesit-explorer-switch-parser): Add a default to
completing-read.
(treesit-explore-mode): Guard completing read quit. Wire up the
new cleanup functions.
This unbreak project-vc-dir for dirs under non-truename
hierarchies.

Fix 'vc-dir-resynch-file' (bug#80803)
* lisp/vc/vc-dir.el (vc-dir-resynch-file): Apply 'file-truename'
instead of 'expand-file-name' to FNAME argument to prevent
spurious display of symlinked files in *vc-dir* buffer.
However the similar command 'M-x project-vc-dir' was broken and made
unusable in similar circumstances.
This relatively simple fix addresses both situations touching only the
problematic 'vc-resynch-file' and one of its callees,
'vc-dir-recompute-file-state', which now discerns clearly between the
short/familiar name to present in the list and the "fname" to use to
call into the backend to gather the VC state. Since this function is
also called from another context, where the requirements are less clear,
keeping current smenatics in that situation seemed prudent, so the new
behaviour is activate with a new optional parameter.
* lisp/vc/vc-dir.el (vc-dir-resynch-file): Call
vc-dir-recompute-file-state with truename=t.
(vc-dir-recompute-file-state): Accept optional truename param.
