Helix

In your Helix config folder (~/.config/helix/ by default), create languages.toml if it does not already exist. Add a grammar and language entry for Halcyon:

[[grammar]]
name = "halcyon"
source = { git = "https://git.lgatlin.dev/logan/tree-sitter-halcyon.git", rev = "main" }

[[language]]
name = "halcyon"
scope = "source.hc"
file-types = ["hc"]
grammar = "halcyon"
comment-tokens = ["--"]
block-comment-tokens = { start = "(*", end = "*)" }

Next, fetch and build the grammar. If this is your first time building grammars this will take several minutes.

helix -g fetch
helix -g build

Finally, download the highlight queries to your runtime directory:

mkdir -p ~/.config/helix/runtime/queries/halcyon
wget https://git.lgatlin.dev/logan/tree-sitter-halcyon/raw/branch/main/queries/highlights.scm \
  -O ~/.config/helix/runtime/queries/halcyon/highlights.scm
