README

An advanced configuration of the WordPress coding standards for plugin and theme development.

Usage

• Install Composer
• Run composer init to set up Composer for your project.
• Run composer require wpscholar/phpcs-standards-wpscholar to install the coding standards.
• Run vendor/bin/phpcs . --standard=WPScholar from your project root to check your code.
• Optionally, add a script to your composer.json file so you can just run composer run lint to check your code.

"scripts": {
  "lint": [
    "vendor/bin/phpcs . --standard=WPScholar"
  ],
  "clean": [
    "vendor/bin/phpcbf . --standard=WPScholar"
  ]
}

Additional Notes

• Append the -s flag to see the internal names of the rules.
• Add --runtime-set testVersion 8.0- to check PHP version 8.0 or greater.
• Add a custom phpcs.xml file to your project to customize the ruleset or your desired configuration.

<?xml version="1.0"?>
<ruleset name="Project Rules">
  <rule ref="WPScholar" />
  <config name="testVersion" value="8.0-"/>
  <config name="minimum_supported_wp_version" value="6.0"/>
</ruleset>

IDE Integration

Some IDE integrations of PHPCS will fail to register your ruleset since it doesn't live in your project root. In order to rectify this, place phpcs.xml at your project root:

<?xml version="1.0"?>
<ruleset name="Project Rules">
    <rule ref="WPScholar"/>
</ruleset>
