Integration/configuration of tree-sitter-rstml

[vincentberthier]

There is a project intended to offer better syntax highlighting when developing with Rust web frameworks such as Leptos: https://github.com/rayliwell/tree-sitter-rstml

Problem is, I have absolutely no idea of how to do this. It explains how for Neovim, so hopefully it isn’t that hard though?

Anyone willing to have a look and share how it’s done?

Maintainer of tree-sitter-rstml here,

Helix queries and instructions should probably be up within a few days.

Once they are mature enough, I'd be happy to open a pull request to merge them into helix.

Cool!

My config is helix config.
