Derive a grammar

[SuperBo]

Hi Shadaj,

I am very interested in this project when I read this blog.

Tree-sitter provides a mechanism for deriving a language (grammar) as you can see in this:

• https://github.com/tree-sitter/tree-sitter-typescript/blob/ebd10b475722d59a1fa7e4b38047e768413794fc/common/define-grammar.js#L24
• https://github.com/tree-sitter/tree-sitter-cpp/blob/d5e90fba898f320db48d81ddedd78d52c67c1fed/grammar.js#L23

This is helpful when you want to parse a language which has many dialects (e.g TSX and Typescript), or in case your language have different standards (e.g C++11, C++14, C++18).

I wonder there is a way can do that with Rust Sitter.

Regards,
