GitHub Action for PHP-CS-Fixer

NOTE: If you didn't create a .php-cs-fixer.dist.php file, do that first before adding this workflow. An example of this file created by the creators of PHP-CS-Fixer can be found here.

Usage

You can use it as a GitHub Action like this:

# .github/workflows/lint.yml

on: [push, pull_request]
name: Main
jobs:
  php-cs-fixer:
    name: PHP-CS-Fixer
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
    - name: PHP-CS-Fixer
      uses: docker://oskarstark/php-cs-fixer-ga

To use a custom config, e.g. --diff and --dry-run options:

# .github/workflows/lint.yml

on: [push, pull_request]
name: Main
jobs:
  php-cs-fixer:
    name: PHP-CS-Fixer
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
    - name: PHP-CS-Fixer
      uses: docker://oskarstark/php-cs-fixer-ga
+     with:
+       args: --config=.project.php_cs --diff --dry-run

Usage with cache

Add .php-cs-fixer.cache to .gitignore, then:

on: [push, pull_request]
name: Main
jobs:
  php-cs-fixer:
    name: PHP-CS-Fixer
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: actions/cache@v3
        with:
          path: .php-cs-fixer.cache
          key: ${{ runner.OS }}-${{ github.repository }}-phpcsfixer-${{ github.sha }}
          restore-keys: |
            ${{ runner.OS }}-${{ github.repository }}-phpcsfixer-

      - name: PHP-CS-Fixer
        uses: docker://oskarstark/php-cs-fixer-ga
