Action — setup-python

Installs Python with uv and restores the uv dependency cache.

Usage

steps:
  - uses: actions/checkout@v4

  - uses: KevinDeBenedetti/github-workflows/.github/actions/setup-python@main
    with:
      python-version: '3.12'

Inputs

Input	Type	Default	Description
python-version	string	'3.12'	Python version to install
working-directory	string	'.'	Directory containing pyproject.toml
install	boolean	true	Run uv sync after setup

Outputs

Output	Description
cache-hit	Whether the uv cache was restored

Steps

1. Install uv (latest)
2. Setup Python python-version
3. Restore uv cache keyed on uv.lock
4. Run uv sync --frozen

Notes

• install: 'false' skips the uv sync step — useful when you only need the Python + uv toolchain.
• Cache key is scoped to runner.os, python-version, and the hash of uv.lock, so cache is invalidated when dependencies change.
