defined by 'treesit-defun-type-regexp'.
(html-ts-mode--outline-predicate): New function.

in 'treesit-thing-settings'. Use "tag_name" and "attribute"
in 'sentence' to conform to sentence navigating arguments
in other ts-modes. Remove unnecessary heading
from 'treesit-simple-imenu-settings' and use "element"
supported by 'html-ts-mode--defun-name'.

Set 'treesit-simple-imenu-settings' and 'treesit-outline-predicate'.
Use 'kill-local-variable' for 'forward-sexp-function'
and 'show-paren-data-function' instead of resetting their value.
* lisp/treesit.el (treesit-outline-search): Check for the thing
before the end of the line to support such case when the thing
fits on the current line and ends before the end of the line
such as e.g. '<h1>...</h1>' in html-ts-mode.
(treesit-hs-find-next-block, treesit-hs-inside-comment-p):
Use anchors for "\\`comment\\'" (bug#75609).
* lisp/treesit.el (treesit-node-at): Make the logic for finding
the parser (and the root node) more explicit and
straightforward. Don't use treesit-buffer-root-node; instead,
find the parser and use treesit-parser-root-node directly.

New buffer-local variable.
(hs-hide-block-at-point): Check if 'hs-block-end-regexp' is

(hs-hide-all): Don't use 'hs-block-start-regexp' when it's not a string.

(treesit-imenu): Fix tests.
Up to this point, functions in
treesit.el (font-lock/indentation/etc) creates a parser if one
doesn't exist. This doesn't work well with local parsers,
because local parsers are not visible at global level and
font-lock or indentation functions might accidentally create a
global parser for an embedded language.
The solution is to not create parsers automatically. This has
the potential of breaking things, but I don't expect any actual
breakage: all the major modes create parsers they need in the
major mode body, even though previously it isn't technically
necessary.
* lisp/treesit.el (treesit-buffer-root-node):
(treesit--update-ranges-local):
(treesit-update-ranges):
(treesit--guess-primary-parser): Use treesit-parser-list instead
of treesit-parser-create.
This should help major modes to support grammar versions.
* doc/lispref/parsing.texi (Pattern Matching): Mention new function.
* lisp/treesit.el (treesit-query-first-valid): New function.
(treesit-query-valid-p): New function.
* lisp/treesit.el (treesit-major-mode-setup): Move setting of
'transpose-sexps-function' outside of 'treesit-thing-defined-p'
since 'treesit-transpose-sexps' doesn't depend on the 'sexp' thing.
* lisp/textmodes/yaml-ts-mode.el (yaml-ts-mode):
Add 'treesit-thing-settings' with the 'list' thing,
but use it only for list commands, not sexp commands (bug#73404).
* lisp/treesit.el (treesit--forward-list-with-default): Improve to
better support the case when point is inside an opening/closing node
with a name longer than 1 character such as "#if" and "#endif".
(treesit-navigate-thing): No need to check for thing 'list'
since list commands now use other functions.
* lisp/progmodes/c-ts-mode.el (c-ts-mode--thing-settings): Add
more preproc nodes such as #if/#endif and #ifdef/#endif and their
variants to the 'list' thing.
* doc/lispref/parsing.texi (User-defined Things): Mention new
functions 'treesit-forward-list', 'treesit-down-list',
'treesit-up-list', 'treesit-show-paren-data' that use the thing
'list' with the symbol property 'treesit-thing-symbol' (bug#73404).
* lisp/treesit.el: Put the property 'treesit-thing-symbol'
on the symbol 'list'.
(treesit--forward-list-with-default, treesit-down-list)
(treesit-up-list, treesit-navigate-thing)
(treesit-show-paren-data--categorize, treesit-major-mode-setup):
Replace 'sexp-list' with 'list'.

* lisp/progmodes/js.el (js-ts-mode):

Replace 'sexp-list' with 'list'.
* src/treesit.c (treesit_traverse_validate_predicate)
(treesit_traverse_match_predicate): Check if the 'pred'
symbol has the property 'Qtreesit_thing_symbol'.
(syms_of_treesit): New symbol 'Qtreesit_thing_symbol'.
(treesit--forward-list-with-default): New internal function
with body from 'treesit-forward-sexp-list' (bug#73404).
(treesit-forward-sexp-list, treesit-forward-list):
Replace body with a call to the shared implementation
'treesit--forward-list-with-default' using the
corresponding default function as an argument.
(treesit-show-paren-data--categorize): Use 'treesit-thing-defined-p'
to check if the thing exists for the language at POS before calling
'treesit-parent-until' that raises an error for an undefined thing.
(treesit-thing-defined-p): Add the alias signature to the docstring.
Use 'treesit-thing-next' and 'treesit-thing-prev' with
'treesit-node-named' to transpose named siblings that leaves the right
punctuation in anonymous nodes between named siblings. Fall back
to 'transpose-sexps-default-function' inside strings and comments.
(treesit-node-named): New helper function.
* lisp/treesit.el (treesit-explore-mode): We added the hook to
kill-buffer-hook, so make sure to remove it from
kill-buffer-hook, not post-command-hook.
* lisp/treesit.el (treesit-forward-sexp-list): Rewrite to support
the value of ARG more than 1. In this case every step moves forward
either over the next treesit-based list or over the syntax-based symbol.
(treesit-down-list, treesit-up-list): Rewrite to support the fallback
to the syntax-based navigation while inside the treesit-based list.
Also use a loop for ARG more than 1 (bug#73404).
Copy the implementation of treesit-parent-until here, and call
its treesit-node-match-p with the argument IGNORE-MISSING set to t
that causes it to fail silently instead of raising an error when
the predicate 'sexp-list' is not defined in an embedded language.
(treesit-major-mode-setup): Set show-paren-data-function to
treesit-show-paren-data only when 'sexp-list' thing is defined
that is used by treesit-show-paren-data--categorize (bug#75198).
* admin/tree-sitter/compat-template.html: Update template.
* admin/tree-sitter/treesit-admin.el:
(treesit-admin--builtin-language-sources): Add sources.
(treesit-admin--builtin-modes): New variable.
(treesit-admin--verify-major-mode-queries): Don't need to pass
LANGS argument anymore.
(treesit-admin-verify-major-mode-queries): Move, and use
treesit-admin--builtin-modes.
(treesit-admin--mode-languages): Set some variables so it gets
all the languages.
(treesit-admin--find-latest-compatible-revision): Also return
commit timestamp.
(treesit-admin--generate-compatibility-report): New parameter
EMACS-EXECUTABLES. Support generating report for multiple Emacs
versions.
* lisp/treesit.el (treesit--language-git-timestamp): New function.
Make treesit-admin--verify-major-mode-queries use
treesit--install-language-grammar-1, rathre than the interactive
command treesit-install-language-grammar.
* admin/treesit-admin.el:
(treesit-admin--verify-major-mode-queries): Add parameter
SOURCE-ALIST. Use treesit--install-language-grammar-1.
(treesit-admin-verify-major-mode-queries): Pass
treesit-admin--builtin-language-sources to
treesit-admin--verify-major-mode-queries.
* lisp/treesit.el (treesit-install-language-grammar): Don't
return revision of the git repo.
Separate treesit--install-language-grammar-1 into two functions,
one clones the repository, the other builds and installs the
grammar.
* lisp/treesit.el (treesit--install-language-grammar-1):
Refactor out treesit--build-grammar.
(treesit--build-grammar): New function.
(treesit--language-git-revision): Now takes REPO-DIR as an
argument.
* lisp/treesit.el (treesit-show-paren-data--categorize):
New internal function.
(treesit-show-paren-data): New function.
(treesit-major-mode-setup): Set 'show-paren-data-function' to
'treesit-show-paren-data'.
* lisp/emacs-lisp/lisp.el (up-list-function): New variable (bug#73404).
(up-list-default-function): New function.
(up-list): Split part to 'up-list-default-function'.
* lisp/treesit.el (treesit-up-list): New function.
(treesit-major-mode-setup): Set 'up-list-function' to
'treesit-up-list'.
