no highlighting: --health says ok, but when opening file, "the parser's shared library does not exist"

[2-www]

Summary

all black text for all languages, even tho --health reports ok:

Reproduction Steps

1. hx --health python
2. hx somecode.py

I expected this to happen: code is colorful

Instead, this happened: code is all black text(

can you try hx -g fetch and hx -g build?

[2-www]

thank you, i will do that, i checkeded /usr/lib/hx/runtime/grammars/ and it is indeed empty (so --health output wrong)

[2-www]

do you know if it's possible to not build /all/ of the gramars?

[2-www]

i read https://github.com/helix-editor/helix/blob/master/helix-loader/src/grammar.rs and did this:

# cat ~/.config/helix/languages.toml 
[use-grammars]
only = ["python"]

[2-www]

it works, thank you!

[2-www]

i'll still leave this open because output of --health is not correct

[m4rch3n1ng]

looked into it, cannot reproduce, if it cannot find the grammar it prints Tree-sitter parser: None for me.

looked into the code and the code that prints None and logs the Skipping syntax config for ... info message are doing the exact same check, so i heave no idea what's going on on your side:

	return Ok(None);
