tree-sitter-toolang

Tree-sitter grammar for Toolang.

This repository publishes:

  • the npm grammar package tree-sitter-toolang
  • the Python extension package tree-sitter-toolang
  • the Rust crate tree-sitter-toolang

Install

Python

python -m pip install tree-sitter-toolang tree-sitter

import tree_sitter_toolang
from tree_sitter import Language, Parser

language = Language(tree_sitter_toolang.language())
parser = Parser(language)
tree = parser.parse(b"with skill a/b\n")

The Python package also exposes packaged query strings: HIGHLIGHTS_QUERY, INJECTIONS_QUERY, INDENTS_QUERY, OUTLINE_QUERY, and TAGS_QUERY.

Tree-sitter CLI

Install tree-sitter-toolang or clone this repository, then make sure the directory that contains tree-sitter-toolang is listed in your Tree-sitter parser-directories.

tree-sitter init-config
tree-sitter dump-languages
tree-sitter parse path/to/file.too
tree-sitter highlight path/to/file.too
tree-sitter tags path/to/file.too

Installing the npm package alone does not make tree-sitter dump-languages discover Toolang automatically. The package must still live under one of the configured parser-directories, or the grammar path must be provided explicitly.

Rust

[dependencies]
tree-sitter = "0.25"
tree-sitter-toolang = "0.0.11"

let language = tree_sitter::Language::new(tree_sitter_toolang::LANGUAGE);

Development

Edit:

  • grammar.js
  • queries/*.scm
  • test/corpus/*.txt

Regenerate and test:

npm install
npm run generate
npm test
npm run test:cli
npm run build:wasm
cargo test
python -m pip install -e .[tests]
pytest tests

Publishing

Trusted publishers are configured in GitHub Actions with release.yml.

To publish the Rust crate automatically, add the repository secret CRATES_IO_TOKEN.

Verify the npm package locally:

npm publish --dry-run

Verify the Python distributions locally:

python -m pip install --upgrade pip build twine
python -m build
python -m twine check dist/*

Verify the Rust crate:

cargo publish --dry-run

Release checklist:

  1. Bump the version in package.json, pyproject.toml, and Cargo.toml.
  2. Confirm CI is green.
  3. Push the version commit to main.
  4. Create and push a matching tag such as v0.0.11.
  5. GitHub Actions publishes npm and PyPI automatically.
  6. GitHub Actions also publishes the Rust crate when CRATES_IO_TOKEN is set.

The release workflow skips npm, PyPI, or crates.io if that version already exists on the registry. The git tag must match the package version.
