When writing c-ts-mode Theo used parent-bol which works well except
one case:
1 for (int i=0;
2 i < 5;
3 i++) {
4 func(i);
5 }
In this case, when indenting "func(i)", parent-bol returns the start
of "i++" on line 3, instead of the "correct" anchor, the start of
"for" on line 1. parent-bol would have worked if the "for (...) {"
part is in one line.
To support this case I tried numerous things and added a bunch of
stuff, culminating in c-ts-common-statement-offset. It's complicated,
requires extra setup, and slow.
Not anymore! I think the new anchor standalone-parent really captures
the logic behind how people expect indentation to work. It's simple
and fast, and requires no setup.

Now prev-adaptive-prefix looks at the current line and checks if it
begins with a prefix itself. If it does, prev-adaptive-prefix tries
to place the anchor before the prefix on the previous line, rather
than after it.
- prev line
- this line -> This line starts with a "-", i.e., begins with a
prefix, so we place the anchor at the beginning of the
"-" of the previous line, rather than after it
- prev line
this line -> This line doesn't start with a prefix, so the anchor
is placed after the previous line's "-".

There are two possible ways to solve the problem raised in the bug
report: either make sure NODE is never the root (so that parent is
never nil), or allow parent to be nil.
If we go with the latter, a lot of matcher and anchor functions need
change (they need to guard against a null parent). I tried it, and
needing to check for null parent is pretty annoying. In comparison,
if NODE is never the root, it is very convenient for the user, and it
doesn't complicate the rule that much (and it's rather intuitive,
people usually don't think of the case where NODE is the root node).
So that's what I choose.
* doc/lispref/modes.texi (Parser-based Indentation): Update manual.
* lisp/treesit.el (treesit-indent-function): Update docstring.
(treesit--indent-1): Make sure NODE is not the root.
* doc/lispref/modes.texi (Parser-based Font Lock):

treesit-load-suffixes with dynamic-library-suffixes.

Fix pxref to Parser-based Indentation.
(Tree-sitter C API): Fix function names.
* lisp/treesit.el (treesit--simple-indent-eval): Remove cond BODY
duplicated from CONDITION.
(treesit)<define-short-documentation-group>: Fix function names.
"Language grammar" is apparently the more widely used term among
people talking about tree-sitter. To avoid confusion, I think it's
good to use that rather than "language definition", which is a term
that I made up :-)
Feel free to revert this if it is too much change.

We didn't add an integration for Imenu because we aren't sure what
should it look like. Now we have a pretty good idea. All the major
modes copy-paste the two Imenu functions and tweaks them in a standard
way. With the addition of treesit-defun-type-regexp and
treesit-defun-name-function, now is a good time to standardize Imenu
integration.
In the next commit we update all the major modes to use this
integration.
* doc/lispref/modes.texi (Imenu): Add manual.
* doc/lispref/parsing.texi (Tree-sitter major modes): Update manual.
* lisp/treesit.el (treesit-simple-imenu-settings): New varaible.
(treesit--simple-imenu-1)
(treesit-simple-imenu): New functions.
(treesit-major-mode-setup): Setup Imenu.
Now indent and filling works like in c-mode. The only noticeable
missing piece is that the "*/" is not attached to the last sentence
when filling. c-mode does it by replacing whitespaces between the
"*/" and the end of the last sentence with xxx, fill it, then change
the xxx back. I don't know if we should do that in c-ts-mode's filling.
* doc/lispref/modes.texi (Parser-based Indentation): Add new preset.
* lisp/progmodes/c-ts-mode.el (c-ts-mode--indent-styles): Add new
indent rule.
(c-ts-mode--fill-paragraph): New function.
(c-ts-base-mode): Setup paragraph-start, adaptive-fill, etc.
* lisp/treesit.el (treesit-simple-indent-presets): Add new preset.
Comment indentation should use a adaptive-fill-based indent, rather
than comment-start-skip.
Also remove manual description of removed variables in treesit.el and
add documentation for n-p-gp upon request.
* doc/lispref/modes.texi (Parser-based Indentation)
* lisp/treesit.el (treesit-simple-indent-presets): Add n-p-gp, remove

treesit-comment-start/end.
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)

Change from
(START END NODE OVERRIDE &rest _)
to
(NODE OVERRIDE &rest _)
START and END aren't used frequently enough to justify. If a

Before this change, we rebind font-lock-fontify-region-function and
call font-lock's function in tree-sitter's function, and the order of
fontification is tree-sitter, font-lock syntax, font-lock regexp.
Now we make font-lock's syntax function customizable and replace it
with tree-sitter's function, and the order of fontification is
tree-sitter, font-lock regexp.

font-lock functions.
(treesit-font-lock-enable): Remove this function. It is not used even
before this change.

font-lock-fontify-region-function, now bind to
font-lock-fontify-syntactically-function. And we can let font-lock do
it's thing.
* doc/lispref/modes.texi (Parser-based Indentation): Document the
semantic clearly.
* lisp/treesit.el (treesit-simple-indent-presets): Replace with
current-indentation.

always the smallest node above NODE that spans BOL.
(treesit-indent): Don't use save-excurtion, no one else does.
