The goal is to indent like this:
/* comment
comment --> This line aligns with the beginning of the first line
*/ --> This line aligns with the opening comment token
* lisp/treesit.el (treesit-comment-start)
(treesit-comment-end): New variables.

* doc/lispref/parsing.texi (Tree-sitter major modes): Update manual.
This mode is basically the tree-sitter playground[1] in Emacs:
displays the syntax tree with the source side-by-side, kept in sync in
real-time.

First of all, we signal error on using an outdated node, so if a node
has changes, calling treesit-node-check would only raise an error.
Besides, in order to properly answer whether a node has changed, we
would have to update the node as the buffer is edited, which we don't
do right now.
* doc/lispref/parsing.texi (Accessing Node Information): Remove
relevant manual text.
* src/treesit.c (Ftreesit_node_check): Remove docstring mentions,
remove the branch for "has-changes".
(syms_of_treesit): Remove has-changes.
* doc/lispref/parsing.texi (Retrieving Node): Update manual.
* lisp/treesit.el (treesit-node-at): Change semantic. It tries to
return the node that a user would expect in various circumstances.
* test/src/treesit-tests.el (treesit-node-at): New test.
* doc/lispref/parsing.texi (Multiple Languages): Extend and update
manual.
* lisp/treesit.el (treesit-range-functions): Remove variable.
(treesit-range-settings): New variable.
(treesit-range-rules): New function.
(treesit--merge-ranges): New function.
(treesit-update-ranges): Use treesit-range-settings instead of
treesit-range-functions.
(treesit-font-lock-rules): Fix docstring.
(treesit-indent)
(treesit-indent-region): Only update ranges in a region.
* test/src/treesit-tests.el (treesit-range): New test.
Additionally, print node's position in buffer.
* doc/lispref/parsing.texi (Retrieving Node): Reflect this change in
manual.
* src/print.c (print_vectorlike): Remove printing of buffer, add
printing of node position.
* lisp/treesit.el (treesit-language-at-point-function): New local
variable.
(treesit-language-at): Change to use
treesit-language-at-point-function rather than trying each parser
one-by-one.
* doc/lispref/parsing.texi (Multiple Languages): Update manual.
With NODE argument we can do
(setq node (treesit-search-forward-goto node))
And we can choose what node to pass to it (maybe we want to pass it
the largest node at point, rather than the smallest node, and in case
of multiple parsers, we can choose which parser to use).
* doc/lispref/parsing.texi (Retrieving Node): Update manual.
* lisp/treesit.el (treesit-search-forward-goto): Accept a NODE
argument.
* doc/lispref/parsing.texi (Retrieving Node): Update manual.
* lisp/treesit.el (treesit-node-at): Add a (when node) form just to be
explicit, return the last leaf node if there is no node after POS.
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.
* doc/lispref/parsing.texi (Parsing Program Source):
* doc/lispref/modes.texi (Font Lock Mode)
(Parser-based Font Lock): Fix wording, punctuation, and markup.
Add index entries.
* lisp/treesit.el (treesit-node-at, treesit-language-at): Rename
argument POINT to POS.
* doc/lispref/modes.texi: Update manual to reflect previous change:
remove :toggle and :level, add :feature. Document new variables and
functions.
* doc/lispref/parsing.texi: Add the missing closing bracket in
@code{(t . nil)}.
* src/treesit.c (ts_load_language): Better formatted signal data,
(Ftreesit_langauge_available_p): Optionally return the signal data if
language not available.
* doc/lispref/parsing.texi: Document the signal data in detail.
Because treesit-query-capture can now do everything it does.
* doc/lispref/parsing.texi (Pattern Matching): Update manual.
* lisp/treesit.el (treesit-query-in): Remove function.
* src/treesit.c (Ftreesit_query_capture): Accept parser and language
symbol as NODE.
* doc/lispref/parsing.texi (Retrieving Node): Update manual.
* lisp/treesit.el (treesit-search-forward-goto): Instead of taking a
node, use the node at point, and make sure we make progress.
