lezer-tasl

A Lezer grammar for the tasl schema language.

⚠️ This is a low-level library for parsing the AST of the schema language - if you want to parse .tasl files into proper tasl.Schema objects, you want to use the main tasl package instead.

Contributing

This library is just intended to export the compiled lezer grammar, so I don't expect to add any features or functionality beyond that. If you find issues with the grammar definition itself please open an issue to discuss them!
