How do I get highlights working for templ files?

[Teajey]

I want to edit .templ files in Helix for my Go server: https://github.com/a-h/templ

I've gotten as far as successfully adding the language and grammar:

[[language]]
name = "templ"
auto-format = true
scope = "source.templ"
injection-regex = "templ"
grammar = "templ"
file-types = ["templ"]
roots = ["go.sum"]
comment-token = "//"
indent = { tab-width = 4, unit = "\t" }
language-server = { command = "templ", args = ["lsp"] }
formatter = { command = "templ" , args = ["fmt"] }

[[grammar]]
name = "templ"
source = { git = "https://github.com/vrischmann/tree-sitter-templ", rev = "6ab863186d1ba91718125f59deae6cf68d765fcb" }

The tree-sitter grammar appears to have support for highlights: https://github.com/vrischmann/tree-sitter-templ/tree/master/queries

But after running hx --grammar fetch and hx --grammar build I'm still not seeing highlights in the editor, or under --health:

[thomas@thomas-mbp ~/.config/helix] hx --health templ
Configured language server: templ
Binary for language server: /Users/thomas/go/bin/templ
Configured debug adapter: None
Highlight queries: ✘
Textobject queries: ✘
Indent queries: ✘
[thomas@thomas-mbp ~/.config/helix]

Any ideas what I might be missing?

You need to also write highlight queries: https://docs.helix-editor.com/guides/adding_languages.html#queries

It won't work if the queries are just in the grammar folder -- they have to be in runtime/queries

[Teajey]

Ah, okay. Why is that? I imagined hx --grammar fetch or hx --grammar build would take care of something like that automatically

[kirawi]

So we can provide better highlight queries. Queries in repos are usually very basic, tailored for neovim, or they have none.

@Teajey,
Did you get everything to work?

Can you please guide me in getting this setup?

Like the folder structure and files added, or perhaps share your Dotfile repo?

[Teajey]

Sorry, I don't use Templ these days. I've just stuck with using Go's standard templates

Both LSP and tree-sitter seem to work for me out of the box
