To make it easier to follow along, I have created a small GitHub template repository at stefmolin/pre-commit-example with a Python package skeleton for a dummy package called example, but you can also use a Python project of your own.

name: pre-commit on: pull_request: push: branches: [main] jobs: pre-commit: runs-on: ubuntu-latest steps: - uses: actions/checkout@v3 - uses: actions/setup-python@v3 - uses: pre-commit/action@v3.0.1

name: pre-commit on: pull_request: push: branches: [main] jobs: pre-commit: runs-on: ubuntu-latest steps: - uses: actions/checkout@v3 - uses: actions/setup-python@v3 - uses: pre-commit/action@v3.0.1

August 19, 2024 - Here’s an example of how to integrate pre-commit with GitHub Actions: Create a .github/workflows/pre-commit.yml file in your repository with the following content: name: pre-commit on: [push, pull_request] jobs: pre-commit: runs-on: ubuntu-latest steps: - uses: actions/checkout@v2 - name: Set up Python uses: actions/setup-python@v2 with: python-version: '3.x' - name: Install dependencies run: pip install pre-commit - name: Run pre-commit hooks run: pre-commit run --all-files

Now try editing a Python file (add spaces at the end of the file or change the formatting of something). Then try committing it: git add .pre-commit-config.yaml git commit -m "Test pre-commit"
