The direct cause of the problem in the bug report is that when
user runs treesit-font-lock-recompute-features to add the
emacs-devel feature in c-ts-mode's mode hook, the added query
for emacs-devel aren't compiled.
This change consists of two parts:
1. The immediate fix: validate and compile queries in
treesit-font-lock-recompute-features.
2. To make it more fool-proof, change treesit-font-lock-rules
back to compile the queries and make
treesit--compile-query-with-cache support compiled queries. This
way, as long as the query goes through treesit-font-lock-rules,
it'll be compiled eventually and not cause slow-down. I had to
add some c-level functions, but they're kind of overdue anyway,
so I don't have any problem adding them to the API.
* lisp/treesit.el (treesit--compile-query-with-cache): Support
compiled queries.
(treesit-font-lock-rules): Compile the queries (but not
eagerly).
(treesit-font-lock-recompute-features): Validate and compile
queries.
(treesit-major-mode-setup): Remove call to

called in treesit-font-lock-recompute-features.
* src/treesit.c (Ftreesit_query_eagerly_compiled_p):

* doc/lispref/parsing.texi (Pattern Matching): Add manual

Latest tree-sitter library throws a syntax error if the
predicate names in a query don't end with question mark. So we
made the following change:
:equal changed to :eq?
:match changed to :match?
:pred changed to :pred?
Old names are transparently converted to new names when
expanding patterns.
:match predicate can now take the regexp and the node in any
order: it'll figure out which is which automatically. This way
it works with current Emacs convention (regexp first), as well
as tree-sitter's match convention (regexp second).

Add line-column tracking for tree-sitter parsers. Copied from
comments in treesit.c:
Technically we had to send tree-sitter the line and column
position of each edit. But in practice we just send it dummy
values, because tree-sitter doesn't use it for parsing and
mostly just carries the line and column positions around and
return it when e.g. reporting node positions[1]. This has
been working fine until we encountered grammars that actually
utilizes the line and column information for
parsing (Haskell)[2].
[1] https://github.com/tree-sitter/tree-sitter/issues/445
[2] https://github.com/tree-sitter/tree-sitter/issues/4001
So now we have to keep track of line and column positions and
pass valid values to tree-sitter. (It adds quite some
complexity, but only linearly; one can ignore all the linecol
stuff when trying to understand treesit code and then come
back to it later.) Eli convinced me to disable tracking by
default, and only enable it for languages that needs it. So
the buffer starts out not tracking linecol. And when a
parser is created, if the language is in
treesit-languages-require-line-column-tracking, we enable
tracking in the buffer, and enable tracking for the parser.
To simplify things, once a buffer starts tracking linecol, it
never disables tracking, even if parsers that need tracking
are all deleted; and for parsers, tracking is determined at
creation time, if it starts out tracking/non-tracking, it
stays that way, regardless of later changes to
treesit-languages-require-line-column-tracking.
To make calculating line/column positons fast, we store
linecol caches for begv, point, and zv in the
buffer (buf->ts_linecol_cache_xxx); and in the parser object,
we store linecol cache for visible beg/end of that parser.
In buffer editing functions, we need the linecol for
start/old_end/new_end, those can be calculated by scanning
newlines (treesit_linecol_of_pos) from the buffer point
cache, which should be always near the point. And we usually
set the calculated linecol of new_end back to the buffer
point cache.
We also need to calculate linecol for the visible_beg/end for
each parser, and linecol for the buffer's begv/zv, these
positions are usually far from point, so we have caches for
all of them (in either the parser object or the buffer).
These positions are far from point, so it's inefficient to
scan newlines from point to there to get up-to-date linecol
for them; but in the same time, because they're far and
outside the changed region, we can calculate their change in
line and column number by simply counting how much newlines
are added/removed in the changed
region (compute_new_linecol_by_change).

The previous fix fixed the problem that treesit-parser-create
always use the current buffer, but that introduce another subtle
problem: if an indirect buffer creates a parser, the parser
saves the base buffer rather than the indirect buffer. In Emacs
29, if you create a parser in an indirect buffer, the parser
saves the indirect buffer. This change of behavior breaks some
existing use-cases for people using indirect buffer with
tree-sitter.
In Emacs 31, indirect buffers and base buffer get their own
parser list, so this problem doesn't exist anymore. The fix is
only for Emacs 30.

This is needed for creating embedded parsers for embedded code
blocks of which language cannot be known ahead of time. E.g.,
markdown and org mode's code block.
* src/treesit.c (Ftreesit_query_capture): Add parameter GROUPED.

Add parser properties embed-level and parent-node. They'll be
help us implement arbitrarily nested embeded parser, and
navigation across embedded and host parsers, respectively.
* src/treesit.c:
(Ftreesit_parser_embed_level):
(Ftreesit_parser_set_embed_level):
(Ftreesit_parser_parent_node):
(Ftreesit_parser_set_parent_node): New functions.

* src/treesit.c (treesit_sync_visible_region): Use character position
instead of byte position when comparing to ranges, because the
ranges are in character position.

* src/treesit.c (resolve_language_symbol): Move forward.
(treesit_ensure_query_compiled): Resolve language remapping
here.
(Ftreesit_parser_list): Don't resolve language remaping here,
because there's no need: parsers now carries the remapped
language.
(Ftreesit_query_compile): Don't resolve language remapping here,
because we resolve language remapping when actually compiling
the query. Also we want the query to carry the unmapped
language.
