VCL language failing syntax highlighting

[salarkhan]

i often work on a language with no lsp/treesitter out there (VCL). with vim, i just set syntax=ruby and i'm good to go.

with helix's language model, i figured setting the treesitter to ruby should suffice, but no dice. i could have sworn i had it working for a moment but i can't figure out where my config is wrong. i checked the logs via :log-open with -vvv passed in, but saw nothing of value:

here's the configuration i set:

[[language]]
name = "vcl"
scope = "source.vcl"
injection-regex = "vcl"
file-types = ["vcl"]
comment-token = "#"
indent = { tab-width = 2, unit = "  " }
roots = []

[[grammar]]
name = "vcl"
source = { git = "https://github.com/tree-sitter/tree-sitter-ruby", rev = "206c7077164372c596ffa8eaadb9435c28941364" }

i've tried older revs for ruby as well to no avail (4c600a463d97e36a0ca5ac57e11f3ac8c297a0fa), as well as other languages (bash).

To re-use ruby's tree-sitter parser you should set grammar = "ruby" in the [[language]] block for vcl. You will also need to set up syntax highlighting queries in $HELIX_RUNTIME/queries/vcl/highlights.scm. If you re-use the ruby tree-sitter parser you can also re-use the syntax highlight queries by adding the comment ; inherits: ruby to that file.

fantastic, got it working now. thanks for the help!

one thing to call out, not sure if it's a bug or expected:

if i re-use the tree-sitter, the comment-token value under [[language]] seems to be ignored
