Helix finds tree-sitter grammar parser, but not highlight queries

[chjlsch]

I created a tree-sitter grammar for a custom config language i'm hacking on called prosa_conf. I got helix to pick up the parser, but not the highlight queries. Using the tree-sitter cli to highlight files works, so i think i'm doing something wrong on the helix config part.

I followed Adding languages and Languages from the helix docs.

The grammar: codeberg.org/chjlsch/tree-sitter-prosa-conf.

Helix version: helix 25.07.1 (a05c151b)

Language config:

[[language]]
name = "prosa_conf"
scope = "source.prosa.conf"
injection-regex = "prosa"
file-types = [
  { glob = "prosa.conf" },
]
roots = ["prosa.conf"]
comment-token = "#"
indent = { tab-width = 4, unit = "\t" }

[[grammar]]
name = "prosa_conf"
source = { git = "https://codeberg.org/chjlsch/tree-sitter-prosa-conf", rev = "134ef0c929f0e6b72eac34fc2275f968f66b3818" }

Helix health (hx --health prosa_conf):

Configured language servers: None
Configured debug adapter: None
Configured formatter: None
Tree-sitter parser: ✓
Highlight queries: ✘
Textobject queries: ✘
Indent queries: ✘

The [[grammar]] config only shows Helix where to find the parser. The queries need to be copied into runtime/helix/<language>/*.scm. We don't use the queries in the grammar repository since they typically do not match the captures we use: https://docs.helix-editor.com/master/themes.html#syntax-highlighting

Ah, now i understand. Thanks!

For future reference:

I placed the highlights.scm in the ~/.config/helix/runtime/queries/<language>/ directory. Now it works.
