Adds some tree-sitter font-locking rules in rust-ts-mode to fontify
meta variables, their types, and repetition operators in macros.
These rules add new font-locking as indicated in the following
snippet:
macro_rules! unsafe_raw_call {
($env:expr, $name:ident $(, $args:expr)*) => {
// ^ font-lock-variable-name-face
// ^ font-lock-type-face
// ^ font-lock-operator-face
// ^
font-lock-operator-face
{
let env = $env;
// ^ font-lock-variable-use-face
let result = unsafe {
let $name = raw_fn!(env, $name);
$name(env.raw $(, $args)*)
};
env.handle_exit(result)
}
};
}
I also removed the last occurrence of the following duplicated rule from
the `type` feature:
(type_identifier) @font-lock-type-face

Great! Thanks! I’ll merge this in some time once I figure out whether
should we apply it to emacs-29 or master.
Meanwhile, it seems that you’ve recently working on tree-sitter modes.
If you’re interested, maybe you can take a look at ert-font-lock, and
add some tests that cover the bugs your patches fixes? This is
completely optional, of course. I bought it up because I think you might
be interested.

Noah,
...and if you decide to add ert-font-lock tests and something is not
working as expected - let me know, happy to fix or extend
ert-font-lock.
Thanks!

I've attached a patch with font-locking tests for the recent additions
in (bug#70464) and (bug#70465). So, it will fail without those being
merged.
Thanks!
