RuboCop Lint

A lightweight composite action for running RuboCop with reviewdog. Use this when Ruby is already set up in your workflow.

Usage

This action assumes Ruby and dependencies are already installed. Perfect for adding linting to an existing job:

jobs:
  ci:
    runs-on: ubuntu-latest
    steps:
      # Setup Ruby (via ruby-ci-setup or manually)
      - uses: 84codes/actions/ruby-ci-setup@main
        with:
          postgres: true

      # Run your tests
      - run: bundle exec rake test

      # Add linting
      - uses: 84codes/actions/rubocop-lint@main
        with:
          github-token: ${{ secrets.GITHUB_TOKEN }}
