# Contributing

We use the [`uv`](https://github.com/astral-sh/uv) package manager. Simply [install `uv`](https://github.com/astral-sh/uv#installation) and run `uv sync` in this repository to build the environment. Run `source .venv/bin/activate` to activate the environment.

We use `ruff check` for linting, `ruff format` for formatting, `pyright` for static type checking, and `pytest` for testing. We expect all such checks to pass before merging changes to the main branch. We build wheels with `uv build` and upload to [PyPI](https://pypi.org/project/torchrunx) with `uv publish`. Our CI pipelines are powered by Github Actions.

## Pull Requests

Make a pull request with your changes on Github and we'll try to look at it soon! If addressing a specific issue, mention it in the PR, and offer a short explanation of your fix. If adding a new feature, explain why it's meaningful and belongs in **torchrunx**.

## Testing

`tests/` contains `pytest`-style tests for validating that code changes do not break the core functionality of our library.

At the moment, we run `pytest tests/test_ci.py` (i.e. simple single-node CPU-only tests) in our Github Actions CI pipeline (`.github/workflows/release.yml`). One can manually run our more involved tests (on GPUs, on multiple machines from SLURM) on their own hardware.

## Documentation

Our documentation is hosted on Github Pages and is updated with every package release. We build our documentation with [Sphinx](https://www.sphinx-doc.org): `source scripts/build_docs.sh`. The documentation will then be generated at `docs/_build/html` (and can be rendered with `python -m http.server --directory docs/_build/html`).
