Hare syntax highlighting not working

[blainsmith]

Summary

I upgraded to Helix to 24.03 and the Hare syntax highlighting stopped working. I can still edit .ha files, but no highlighting is applied.

I noticed in the helix.log that it was attempting to load /usr/lib/helix/runtime/grammars/hare.so and it threw an ERROR log line, but I do not have a grammar set. I never had a grammar set for Hare before. I was able to downgrade back to Helix 23.10 and syntax highlighting worked fine.

• The file ~/.config/helix/languages.toml does not exist
• The file ~/.confg/helix/runtime/grammars/hare.so does not exist
• hx --health reports Hare highlighting is green checkmarked

After installing Helix 24.03 I even re-fetched and re-built my grammars with hx --grammar (fetch|build).

Reproduction Steps

I tried this:

1. hx main.ha

use fmt;

export fn main() void = {
	const greetings = [
		"Hello, world!",
		"¡Hola Mundo!",
		"Γειά σου Κόσμε!",
		"Привіт, світ!",
		"こんにちは世界！",
	];
	for (let greeting .. greetings) {
		fmt::println(greeting)!;
	};
};

Taken from https://harelang.org

I expected this to happen: The main.ha file opened in Helix fine and syntax highlighting of keywords defined in https://github.com/helix-editor/helix/blob/master/runtime/queries/hare/highlights.scm to be applied.

Instead, this happened: The main.ha file opened fine, but no highlighting was applied.

I don't use the grammars, but the syntax highlighting so that should still work which it isn't.

[kirawi]

The grammars are responsible for syntax highlighting, so without them you won't be getting any. You need to enable it in your languages.toml (documentation for it is on the website) and then run hx --grammar fetch && hx --grammar build (assuming you have a semi-recent C/C++ environment)

[blainsmith]

Ah, TIL, thank you. I will try to get things built manually. I thought they were separate.

[blainsmith]

I got it working with the following:

1. Installed https://github.com/tree-sitter/tree-sitter toolchain
2. Cloned https://git.sr.ht/~ecmma/tree-sitter-hare
3. Generated hare.so and moved it into ~/.config/helix/runtime/grammars/

Removing it from use-grammars in languages.toml and running hx --grammar fetch && hx --grammar build didn't rebuild it.
