Publishing

Documentation

The Docs workflow builds the site on every push and pull request to main and devel. It executes the tutorials, generates the API reference and uploads the site. Pushes to devel also deploy it to GitHub Pages at https://max-models.github.io/mpiarray/.

Enable GitHub Pages once in the repository settings, with “GitHub Actions” as the source.

Releases and PyPI

Before merging a release to main, update the version in pyproject.toml, src/mpiarray/__init__.py and CITATION.cff (including its release date), and add the release notes to CHANGELOG.md. On every push to main, the Release workflow:

1. tags the release vX.Y.Z and creates the GitHub release,
2. builds the package with uv build and publishes it to PyPI with trusted publishing (OIDC), if that version is not already on PyPI.

One-time configuration

1. Create an account on PyPI and create or claim your project name.
2. In the PyPI project settings go to “Publishing” → “Add a new publisher” and fill in:
   • PyPI project name: mpiarray (or your project name)
   • Owner: your GitHub username or organization
   • Repository name: mpiarray
   • Workflow name: release.yml
   • Environment name: pypi
3. Optionally, in the GitHub repository settings create an environment named pypi whose deployment branches are limited to main.

Coverage

The tests upload coverage to Codecov. Public repositories need no configuration; for a private one add a CODECOV_TOKEN repository secret.
