Use with a virtualenv

The easiest way to use a virtualenv with this action is to "activate" the environment by adding its bin to $PATH, then allowing pyright to find it there.

- uses: actions/checkout@v3
- uses: actions/setup-python@v4
  with:
    cache: 'pip'

- run: |
    python -m venv .venv
    source .venv/bin/activate
    pip install -r requirements.txt

- run: echo "$PWD/.venv/bin" >> $GITHUB_PATH

- uses: jakebailey/pyright-action@v2

Use with poetry

Similarly to a virtualenv, the easiest way to get it working is to ensure that poetry's python binary is on $PATH:

- uses: actions/checkout@v3

- run: pipx install poetry
- uses: actions/setup-python@v4
  with:
    cache: 'poetry'

- run: poetry install
- run: echo "$(poetry env info --path)/bin" >> $GITHUB_PATH

- uses: jakebailey/pyright-action@v2

Providing a pyright version sourced from preexisting dependencies

The version input only accepts "latest" or a specific version number. However, there are many ways to use specify a version of pyright derived from other tools.

Using pyright from $PATH

If you have pyright installed in your environment, e.g. via the pyright PyPI package, specify version: PATH to use the version that's on $PATH.

- run: |
    python -m venv .venv
    source .venv/bin/activate
    pip install -r dev-requirements.txt # includes pyright

- run: echo "$PWD/.venv/bin" >> $GITHUB_PATH

- uses: jakebailey/pyright-action@v2
  with:
    version: PATH

Keeping Pyright and Pylance in sync

If you use Pylance as your language server, you'll likely want pyright-action to use the same version of pyright that Pylance does. The pylance-version option makes this easy.

If you allow VS Code to auto-update Pylance, then set pylance-version to latest-release if you use Pylance's Release builds, or latest-prerelease if you use Pylance's Pre-Release builds. Alternatively, you can set it to a particular Pylance version number (ex. 2023.11.11).

Note that the version option takes precedence over pylance-version, so you'll want to set one or the other, not both.
