Justification: We want to make the SIDE argument in
treesit-search-forward-goto optional, so I changed it to START.
It makes more sense for BACKWARD to follow START so two common
case, search for end forward and beginning backwards are
(treesit-search-forward-goto node pred)
(treesit-search-forward-goto node pred t t)
Then since we swapped BACKWARD and ALL for
treesit-search-forward-goto, it's best to swap them for
treesit-search-forward and treesit-search-subtree, too. And BACKWARD
will probably be used more frequently than ALL anyway.
* doc/lispref/parsing.texi (Retrieving Node): Resolve FIXME and update
function signitures.
* lisp/treesit.el (treesit-search-forward-goto): Change SIDE to
START, swap BACKWARD and ALL.
(treesit-beginning-of-defun)
(treesit-end-of-defun): Update use of treesit-search-forward-goto
* src/treesit.c (Ftreesit_search_subtree)
(Ftreesit_search_forward): Swap BACKWARD and ALL.
* lisp/treesit.el (treesit-search-forward-goto): Remove UP argument.
* src/treesit.c (treesit_traverse_child_helper): New function.
(treesit_search_forward): Remove UP_ONLY and SKIP_START argument.
Don't traverse subtree of START. And after we've found the next
sibling/parent, go down to the first leaf node. Also change recursion
to loop.
(Ftreesit_search_forward): Change docstring, remove UP argument.
Pattern vs query: a query consists of many patterns. I tightened up
the use of pattern vs query in the manual, now there shouldn't be
ambiguities.
* doc/lispref/modes.texi (Parser-based Font Lock):
* doc/lispref/parsing.texi (Language Definitions): Resolve FIXME's.

Add index entries.
* lisp/treesit.el (treesit-node-at, treesit-language-at): Rename
argument POINT to POS.
Now instead of a toggle function (major-mode-backend-function), we let
major mode set local variables like treesit-font-lock-settings,
treesit-imenu-function, then treesit-mode takes care of activating
those things (clearing font-lock-keywords, setting
imenu-create-index-function to treesit-imenu-function, etc).
js.el and python.el: I've returned js-mode and python-mode to exactly
what they were before tree-sitter change, plus lines at the end
setting up tree-sitter variables. Sorry about all these fuss :-D
* lisp/treesit.el (treesit-mode-inhibit-message): Remove option.
(major-mode-backend-function)
(treesit-remapped-major-mode-alist): Remove variables.
(treesit-mode): Move down to the end of buffer. Do more things.
(global-treesit-mode): Move down to the end of buffer. Don't handle
major-mode-remap-alist anymore.
(global-treesit-mode--turn-on): Move down to the end of buffer.
(treesit-ready-p): Move down to the end of buffer. Changed signature.
(treesit-font-lock-enable): Remove function.

(treesit-end-of-defun): New function.
(treesit-imenu-function): New variable.
(treesit-mode-supported)
(treesit-required-languages)

(treesit--backup-local-variable): New function
* lisp/progmodes/js.el (js-use-tree-sitter): Remove option.
(js--treesit-defun-type-regexp): Remove variable. (Now set inline in
js-mode.)
(js--treesit-beginning-of-defun)
(js--treesit-end-of-defun): Remove functions. (Now use
treesit-beginning/end-of-defun.)
(js--backend-toggle)
(js--json-backend-toggle): Remove function.
(js-mode)
(js-json-mode): Restore back to before tree-sitter changes. Add
tree-sitter setup at the end.
* lisp/progmodes/python.el (python--backend-toggle): Remove function.
(python-mode): Restore back to before tree-sitter changes. Add
tree-sitter setup at the end.
* lisp/progmodes/ts-mode.el (ts-mode--font-lock-settings): Use
js--fontify-template-string.
(ts-mode--fontify-template-string): Remove function (because we can
just use js--fontify-template-string).
(ts-mode--defun-type-regexp): Remove variable (now set inline in
ts-mode).
(ts-mode--beginning-of-defun)
(ts-mode--end-of-defun): Remove functions (now using
treesit-beginning/end-of-defun).
(ts-mode): Setup tree-sitter variables and then turn on treesit-mode
or move to js-mode.
There is now support for three font-locking levels, 'minimal',
'moderate' and 'full'. The richest experience is to be expected from
the 'full', and all levels are enabled by default.
* lisp/progmodes/js.el (js--treesit-font-lock-settings): New defvar
renamed from 'js--treesit-settings'.
(js--treesit-font-lock-settings): New defvar renamed from
'js--json-treesit-settings'.
* lisp/progmodes/ts-mode.el (ts-mode--font-lock-settings): New defvar
renamed from 'ts-mode--settings'.
Basically we now have treesit-mode and global-treesit-mode. Major
modes set major-mode-backend-function which treesit-mode calls to
activate/deactivate tree-sitter.
js.el needs a bit explanation: I'm so sorry for messing up the
history, but basically now js-mode and js-json-mode should be exactly
the same as before any tree-sitter change was introduced, sans some
initialization code that are moved to js(-json)--backend-toggle.
js-mode and js-json-mode now just sets major-mode-backend-function and
initialize with js(-json)--backend-toggle.
* lisp/treesit.el (treesit-mode-inhibit-message): New option.
(treesit-can-enable-p): Remove function.
(major-mode-backend-function)

(treesit-mode)
(global-treesit-mode): New minor modes.
(global-treesit-mode--turn-on)
(treesit-ready-p): New functions.
* lisp/progmodes/python.el: Remove option.
(python--backend-toggle): New function.
(python-mode): Remove the if-form, all the initialization code are
moved to python--backend-toggle, python-mode now just sets
major-mode-backend-function and initialize with
python--backend-toggle.
* lisp/progmodes/js.el (js--treesit-can-enable-p)
(js--json-treesit-can-enable-p)
(js--treesit-enable)
(js--json-treesit-enable): Remove functions.
(js--backend-toggle)
(js-json--backend-toggle): New function.
* lisp/progmodes/ts-mode.el (ts-mode): Use treesit-ready-p.

that on WINDOWSNT the library could be loaded dynamically.

(ts_named_node_p): Add prototypes.
* src/print.c (print_vectorlike):

remove :toggle and :level, add :feature. Document new variables and
functions.
* doc/lispref/parsing.texi: Add the missing closing bracket in
@code{(t . nil)}.
Remove :toggle and :level, add :feature.

(Ftreesit_langauge_available_p): Optionally return the signal data if
language not available.
* doc/lispref/parsing.texi: Document the signal data in detail.
* lisp/progmodes/ts-mode.el (ts-mode): New major mode for TypeScript
with support for tree-sitter. It uses the TSX parser, so that we get
support for TSX as well as TypeScript. If we cannot find tree-sitter,
we default to using js-mode.
See comment on struct Lisp_TS_Query for why. Previous commits adding
python and js support for tree-sitter breaks Emacs build if language
definitions aren't available at build time. This commit fixes that.
Now query object don't compile the query upon creation, but stores the
query source and language symbol, and compiles upon first use (in
treesit-query-capture).
I want ts_ensure_query_compiled to return signal symbol and data
rather than signaling itself, because it's a helper function not lisp
function. But because it calls ts_load_language, I had to update
ts_load_language to also use the signal symbol/data interface.
* src/treesit.h (struct Lisp_TS_Query): Add two new field.
* src/treesit.c (ts_load_language): Return signal symbol and data
rather than signaling itself.
(Ftreesit_langauge_available_p)
(Ftreesit_parser_create): Update usage of ts_load_language
(make_ts_query): Now returns a lisp object.
(ts_query_error_to_string): Moved because it's used by
ts_compose_query_signal_data.
(ts_compose_query_signal_data)
(ts_ensure_query_compiled): New functions.
(Ftreesit_query_compile): Delay compiling the query.
(Ftreesit_query_capture): Instead of creating a query object which
compiles the query, now goes two routes: if QUERY is a query object,
make sure it is compiled and use the TSQuery; if QUERY is a cons or
string, compile directly to TSQuery, and free it after use. Creating
a lisp query requires the language symbol, but in this function we
only have TSLanguage.
* lisp/treesit.el (treesit-node-at): We only need to use
treesit-node-first-child-for-pos. This is both faster for large
buffers and simpler. Also remove the TODO comment.
The diff for js-mode, js-json-mode, js-jsx-mode are a bit strange, but
all we did is to wrap some the old code in
(if tree-sitter
(tree-sitter-enable)
...some old-code)
...other old-code (that’s tree-sitter-agnostic)
* lisp/progmodes/js.el (treesit): Add tree-sitter dependency

(js-mode, js-json-mode, js-jsx-mode): Add support for tree-sitter
functionalities.
