Is there a tree-sitter grammar for RSX/RSTML?

[aguynamedben]

It seems the only attempt at a tree-sitter grammar for RSX/RSTLM was: https://github.com/tjdevries/tree-sitter-rsx

Are there any plans to extend/fork the tree-sitter-rust grammar to add support for RSX?

What editor/extension do you use for actually building things with RSX?

Hi!

What editor/extension do you use for actually building things with RSX?

Currently during proc macro expanding - rstml preserve original spans, so any IDE with "semantic highlight" and proc-macro support should work well.

I tested it with rust-analyzer (on vscode) and IDEA Rust plugin.

Is there a tree-sitter grammar for RSX/RSTML?

I dont think so.

I had no plans for this, and see the following problems with it:

1. The needs to support two sets of rules (one in rstml code itself, and one specific for tree-sitter)
2. as you mention in original issue: js and ts parser are both embed jsx/tsx implementation, which is good for new users, since they don't need to install any specific grammar/plugin for html in js.
   But rstml is just a syntax for macro, and it differ with yew's implementation, so it no chance that Rust original grammar will embed it at some time, is there a way in tree-sitter to extend existing grammar dynamically?
3. Also rstml is library for parsing, not a macro implementation, so other libraries could name entrypoint in different ways.
