Highlighting breaks with Helix editor

[tynanbe]

It looks like it stopped working at this commit: https://github.com/gleam-lang/tree-sitter-gleam/commit/b7ae2c9374083e4f4569a2f9e218efe409f98664

Do you have custom config in ~/.config/helix/languages.toml to update the [[grammar]] block? Generally you can't update the parser alone - if there are breaking changes like in https://github.com/gleam-lang/tree-sitter-gleam/commit/23d2b896514087d97f75a62035b325a4704cbae5 (the parent of the commit you linked) then the queries might fail to compile.

Also see https://github.com/helix-editor/helix/pull/9003 - that PR has the updates for the queries that should fix query compilation.

Using Helix v23.10, with this in languages.toml:

[[grammar]]
name = "gleam"

[grammar.source]
git = "https://github.com/gleam-lang/tree-sitter-gleam"
rev = "23d2b896514087d97f75a62035b325a4704cbae5"

I do see an error in helix.log stating that the Gleam queries couldn't be parsed, after running the following with any rev newer than the above.

> hx --grammar fetch && hx --grammar build

Sounds like I need a newer Helix build?

Yep you need the updates to the highlight query that lives in runtime/queries/gleam/highlights.scm. You can overwrite the one in ~/.config/helix/runtime/queries/gleam/highlights.scm (or $HELIX_RUNTIME/queries/gleam/highlights.scm if you set the HELIX_RUNTIME environment variable) with the latest one from the Helix repo if you don't want to rebuild Helix from source.

Sure enough, the updated queries resolved the issue. Thanks very much; sorry for taking your time!
