Welcome to the Grammar Orchard

This is a space for collective maintenance of tree-sitter grammars.

For users

We provide a collection of grammars that you can use as:

Rust crates (uploaded to crates.io)
Python packages (uploaded to PyPI)
NPM support is being trialed
Archives downloaded from the Release pages of each grammar

All our grammars use the same tree-sitter ABI (currently 14, compatible with tree-sitter 0.20 to 0.26), and will migrate synchronously to newer versions. All our grammars are MIT-licensed or weaker.

Contributions to the grammars are actively reviewed, with an interest in onboarding contributors on the team.

For contributors

You can work on grammars with the following benefits:

not running into systematic conflicts with other contributors, as generated files are not tracked in Git (they are generated for releases in the CI)
using a streamlined release workflow, with automated publishing of bindings to package repositories
getting your contributions reviewed and becoming part of the team (which has a clear governance)
