* lisp/textmodes/markdown-ts-mode.el
(markdown-ts--fontify-delimiter): When `markdown-ts-hide-markup'
is enabled in `markdown-ts-view-mode', also hide the whole line
containing a `fenced_code_block_delimiter' (including its
terminating newline) so Eldoc/LSP markdown snippets render
without stray blank lines around the code block. Scoped to
view-mode and to fenced delimiters on purpose: the same handler
is shared by inline delimiters (emphasis, code span, link
brackets) where munching surrounding whitespace would collapse
word separators, and tuning rendering for
hide-markup-while-editing is not a goal.
The grammar reports leading spaces as part of the atx_heading "marker"
and we cannot use the length of the marker as a result. Instead, count
the number of consecutive # after any blanks to determine its "level."
* lisp/textmodes/markdown-ts-mode.el
(markdown-ts--fontify-atx-heading): Count the octothorpes rather
than using the length of the marker node's text.
Do not assume every command run in
'markdown-ts--run-command-in-code-block' produces output that needs to
be merged from the temp/work buffer into the source buffer. One example
is 'xref-find-definitions', the temp buffer of which is unrelated to the
source buffer.
* lisp/textmodes/markdown-ts-mode.el
(markdown-ts-code-block-commands): Add 'complete-symbol'.
(markdown-ts-code-block-ignore-output-commands): New defvar.
(markdown-ts--run-command-in-code-block): Ignore command output
when necessary.
Replace the "c" character-prompt interactive spec with
'read-multiple-choice', which presents named options instead of
requiring users to decode the prompt string and type a single
character.
* lisp/textmodes/markdown-ts-mode.el
(markdown-ts-table-align-column): Use 'read-multiple-choice'.
Adjust ALIGN docstring punctuation.
* lisp/textmodes/markdown-ts-mode-x.el
(markdown-ts-toc-insert-template): Use 'read-multiple-choice'.
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.

span when the face supports it.

'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.
* 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.

Variable names to control indentation have never been
standardized, but over the years some conventions have naturally
arisen, mostly the use of `FOO-indent-offset`,
`FOO-basic-offset`, or `FOO-indent-level` for `FOO-mode`.
When the new TS modes were introduced, a mistake was made that
I failed to catch at the time, where those modes used
`FOO-mode-indent-offset` instead of the "standard" `FOO-indent-offset`.
In order to save packages like `editorconfig-mode` and `indent-bars-mode`
from having to cater to yet-another-convention, rename those
vars to what they should have been all along.
* lisp/editorconfig.el (editorconfig-indentation-alist): Remove the
ad-hoc entries for the deviating modes using `FOO-mode-indent-offset`.
* lisp/textmodes/toml-ts-mode.el (toml-ts-indent-offset):
* lisp/textmodes/mhtml-ts-mode.el (mhtml-ts-js-css-indent-offset)
(mhtml-ts--js-css-indent-offset):
* lisp/textmodes/html-ts-mode.el (html-ts-indent-offset):
* lisp/progmodes/typescript-ts-mode.el (typescript-ts-indent-offset):
* lisp/progmodes/php-ts-mode.el (php-ts-indent-offset)
(php-ts-js-css-indent-offset, php-ts-html-indent-offset):
* lisp/progmodes/json-ts-mode.el (json-ts-indent-offset):
* lisp/progmodes/java-ts-mode.el (java-ts-indent-offset)
(java-ts-method-chaining-indent-offset):
* lisp/progmodes/go-ts-mode.el (go-ts-indent-offset):
* lisp/progmodes/csharp-mode.el (csharp-ts-indent-offset):
* lisp/progmodes/cmake-ts-mode.el (cmake-ts-indent-offset):
* lisp/progmodes/c-ts-mode.el (c-ts-indent-offset):
Rename `FOO-mode-indent-offset` to `FOO-indent-offset`,
with obsolete alias.
* lisp/textmodes/markdown-ts-mode.el
(markdown-ts-hide-markup): New defcustom controlling
visibility of markup delimiters.
(markdown-ts--fontify-delimiter): Fontify delimiter nodes and
conditionally apply invisibility.
(markdown-ts--set-hide-markup): Internal helper to update
invisibility state.
(markdown-ts-toggle-hide-markup): Interactive command to toggle
delimiter visibility.
(markdown-ts-setup): Initialize delimiter hiding according to
'markdown-ts-hide-markup' and register managed properties.
(markdown-ts--treesit-settings): Use
'markdown-ts--fontify-delimiter' for delimiter nodes.
(require 'outline): Ensure outline faces are available so
headings are fontified correctly on first load.
* lisp/textmodes/page-ext.el (pages-directory-revert-function): New
function.
(pages-directory-list-all-headers-p, pages-directory-count-lines-p)
(pages-directory-regexp): New variables to store the page directory
style. (Bug#80319)
It is both simpler to code and marginally more general (allows
spaces in arguments).

a list.
(yaml-ts-mode-flymake): Adjust accordingly.
* etc/NEWS: Announce the change.

member. Update comment for 'extra_line_spacing.'
* src/buffer.c (syms_of_buffer): Update the docstring of
'line-spacing' to describe the cons cell usage.
* src/buffer.h (struct buffer): Update comment for
'extra_line_spacing'.
* src/frame.c (gui_set_line_spacing): Handle cons cell value for
'line-spacing'. Calculate and set 'extra_line_spacing_above'
for both integer and float pairs.
* src/xdisp.c (init_iterator): Initialize 'extra_line_spacing_above'
from buffer or frame 'line-spacing', handling cons cells for both
integer and float values.

spacing between ascent and descent. Update 'max_extra_line_spacing'
calculation.
(resize_mini_window): Take line spacing into account when resizing the
mini window. Pass height of a single line to 'grow_mini_window' and
'shrink_mini_window'.

argument which defines height of a single line.
* src/window.h (grow_mini_window, shrink_mini_window): Adjust function
prototypes accordingly with unit argument.
* lisp/subr.el (total-line-spacing): New function to calculate total
spacing from a number or cons cell.
(posn-col-row): Use total-line-spacing.

* test/lisp/subr-tests.el (total-line-spacing): New test.
* test/src/buffer-tests.el (test-line-spacing): New test.
* doc/emacs/display.texi (Display Custom): Document that
'line-spacing' can be a cons cell.
(Line Height): Document the new cons cell format for 'line-spacing'
to allow vertical centering.
