lezer-tasl v0.3.0

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.

Testing

Tests use AVA 4 and live in the test directory.

npm run test

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!
