This GitHub Action allows to check your code against the Drupal PHP coding standards.

It has GitHub Annotations working out-of-the box. It's fast and inexpensive (in terms of GitHub Action minutes) compared to most others. This is because it doesn't install composer dependencies. The downside is that all components versions are fixed by the version of the action you are using, and not by your code base.

The Docker image used by this action is automatically built from this repository on https://quay.io/repository/guix77/phpcs-drupal-action

• A Drupal project following the https://github.com/drupal-composer/drupal-project structure;
• A GitHub repository of course.

In the root of your Drupal project, create phpcs.xml:

<?xml version="1.0" encoding="UTF-8"?>
<ruleset name="drupal">
  <description>PHP CodeSniffer configuration for Drupal coding standards.</description>
  <file>./web/modules/custom</file>
  <file>./web/themes/custom</file>
  <arg name="extensions" value="php,module,inc,install,test,profile,theme,css,info,txt,md,yml" />
  <config name="drupal_core_version" value="10" />
  <rule ref="Drupal" />
  <rule ref="DrupalPractice" />
</ruleset>

In the root of your Drupal project, create .github/workflows/drupalCodingStandards.yml:

name: Drupal coding standards

on: [pull_request]

jobs:
  phpcs-drupal:
      name: Drupal coding standards
      runs-on: ubuntu-latest
      steps:
        - uses: actions/checkout@v4
        - uses: guix77/[email protected]

You can customize the trigger of course (\\on: [pull_request]\\).

That's it.

Optionally you could define the memory limit to use when executing phpcs. By default it is set to 128M.

uses: guix77/[email protected]
with:
  memory_limit: 512M

Define this if you get an error like: Fatal error: Allowed memory size of....
