This action is a part of GitHub Actions Library created by rtCamp.

A GitHub Action to perform automated pull request review. It is based on https://github.com/Automattic/vip-go-ci/ but can be used for any WordPress or even PHP projects.

The code review is performed using PHPCS.

Please note that, this action performs pull request review only. If you have an existing project, and you want entire project's code to be reviwed, you may need to do it manually.

1. Create a .github/workflows/phpcs.yml in your GitHub repo, if one doesn't exist already.
2. Add the following code to the phpcs.yml file.

on: pull_request

name: Inspections
jobs:
  runPHPCSInspection:
    name: Run PHPCS inspection
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
      with:
        ref: ${{ github.event.pull_request.head.sha }}
    - name: Run PHPCS inspection
      uses: rtCamp/[email protected]
      env:
        GH_BOT_TOKEN: ${{ secrets.GH_BOT_TOKEN }}
        SKIP_FOLDERS: "tests,.github"
        PHPCS_SNIFFS_EXCLUDE: "WordPress.Files.FileName"
      with:
        args: "WordPress,WordPress-Core,WordPress-Docs"

3. Define GH_BOT_TOKEN using GitHub Action's Secret. See GitHub Token Creation section for more details.

Now, next time you create a pull request or commit on an existing pull request, this action will run.

By default, pull request will be reviwed using WordPress coding and documentation standards. You can change the default by passing different PHPCS Coding Standard(s) in line args = ["WordPress-Core,WordPress-Docs"].

4. In case you want to skip PHPCS scanning in any pull request, add [do-not-scan] in the PR description. You can add it anywhere in the description and it will skip the action run for that pull request.

5. In case you want to skip linting all files on every pull request, set PHP_LINT to false.

You can create GitHub Token from here.

It is necessary that you create this token from a bot user account. Please note that the bot account should have access to the repo in which action is being run, in case it is a private repo. It is compulsory to use a bot account because in GitHub it is forbidden to request changes on your own Pull Request by your own user. Additional benefit of using a bot account is that in a large team, if you use your human account token, you may get flooded with unncessary Github notifications.

Permissions required for this token differ according to which type of repo this workflow has been setup for.

Below is list of PHPCS sniffs available at runtime. You can pass more than one standard at a time by comma separated value.

By default, WordPress-Core,WordPress-Docs value is passed.

• MySource
• PEAR
• PHPCompatibility
• PHPCompatibilityParagonieRandomCompat
• PHPCompatibilityParagonieSodiumCompat
• PHPCompatibilityWP
• PSR1
• PSR12
• PSR2
• Squiz
• WordPress (default)
• WordPress-Core (default)
• WordPress-Docs (default)
• WordPress-Extra
• WordPress-VIP
• WordPress-VIP-Go
• WordPressVIPMinimum
• Zend

If your git repo have a file named phpcs.xml in the root of the repository, then that will take precedence. In that case, value passed to args such as args = ["WordPress,WordPress-Core,WordPress-Docs"] will be ignored.

If your git repo doesn't have phpcs.xml and you do not specify args in main.workflow PHPCS action, then this actions will fallback to default.

Here is a sample phpcs.xml you can use in case you want to use custom sniffs.

Automated Code Review in action

Please note...

1. This action runs only for PRs. It even runs on new commits pushed after a PR is created.
2. This action doesn't run on code in the repository added before this action.
3. This action doesn't run for code committed directly to a branch. We highly recommend that you disable direct commits to your main/master branch.
