    id: linter
    env:
      GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
    with:
      style: 'file'  # Use .clang-format config file
      tidy-checks: '' # Use .clang-tidy config file
      # only 'update' a single comment in a pull request thread.
      thread-comments: ${{ github.event_name == 'pull_request' && 'update' }}
