v4.2.0: 🌈 Resolve latest version instead of downloading latest release

Compare Source

Changes

We got a frist contribution from @​pollenjp!

Thanks to this we are now resolving the latest version and try to find it in the local cache instead of always downloading the latest release from the uv repository.
This new approach is not only more efficient, it also fixes a latent bug in the self-hosted runners tools cache and makes the code more maintainable.

Thank you @​pollenjp!

🚀 Enhancements

• Resolve latest version instead of downloading latest release @​pollenjp (#​178)

🧰 Maintenance

• Add test for python-version @​eifinger (#​177)

v4.1.0: 🌈 Set UV_PYTHON for your workflow

Compare Source

Changes

You can now use the input python-version to set the environment variable UV_PYTHON for the rest of your workflow.
This will override any python version specifications in pyproject.toml and .python-version

- name: Install the latest version of uv and set the python version to 3.12
  uses: astral-sh/setup-uv@v4
  with:
    python-version: "3.12"

You can combine this with a matrix to test multiple python versions:

jobs:
  test:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        python-version: ["3.9", "3.10", "3.11", "3.12"]
    steps:
      - uses: actions/checkout@v4
      - name: Install the latest version of uv and set the python version
        uses: astral-sh/setup-uv@v4
        with:
          python-version: ${{ matrix.python-version }}
      - name: Test with python ${{ matrix.python-version }}
        run: uv run --frozen pytest
