Development

1. right click on project root folder > select open in terminal
2. python -m venv .venv to setup python virtual environment for this project. TIP: copy from here and right click in terminal to paste-and-execute.
3. Dialog should come up asking you want this env as interpreter for project: answer yes.

5. Might get some bits and both e.g. 'install pylint' etc. click install for them.
6. pip install -e .[dev] to install the package (editable) with dev dependencies

Releasing

Note: releasing is only actionable by the repository owner.

Versioning is handled by setuptools-scm: the package version is derived from the git tag, so there is no version number in the source to bump. Publishing to PyPI happens automatically via GitHub Actions (.github/workflows/python-publish.yml) using PyPI Trusted Publishing when a GitHub release is published.

To cut a release:

$env:Path += ";C:\Program Files\GitHub CLI"

gh release create v0.3.3 --generate-notes

That's it. Tag format is vX.Y.Z (or X.Y.Z - both parse). The workflow builds the package with the version taken from the tag and uploads it to PyPI.
