Coder

Coder is a library for automated Drupal code reviews and coding standard fixes. It defines rules for PHP_CodeSniffer

Built-in support for:

• "Drupal": Coding Standards https://www.drupal.org/coding-standards
• "DrupalPractice": Best practices for Drupal module development

Online documentation: https://www.drupal.org/node/1419980

Note that Javascript support has been removed. To check and fix Javascript files please use ESLint and see the Drupal ESLint documentation.

Installation

First, make sure Composer is installed correctly:

which composer

If you get composer not found or similar, follow Composer's installation instructions.

Install Coder (8.x-2.x) in your global Composer directory in your home directory (~/.composer):

composer global require drupal/coder

To make the phpcs and phpcbf commands available globally, add the composer bin path to your $PATH variable in ~/.profile, ~/.bashrc or ~/.zshrc:

export PATH="$PATH:$HOME/.composer/vendor/bin"

Register the Drupal and DrupalPractice Standard with PHPCS:

phpcs --config-set installed_paths ~/.composer/vendor/drupal/coder/coder_sniffer

Usage

Check Drupal coding standards

phpcs --standard=Drupal /file/to/drupal/example_module

Check Drupal best practices

phpcs --standard=DrupalPractice /file/to/drupal/example_module

Automatically fix coding standards

phpcbf --standard=Drupal /file/to/drupal/example_module

Working with Editors

Drupal Code Sniffer can be used with various editors.

Automated Testing (PHPUnit + PHPCS)

Coder Sniffer comes with a PHPUnit test suite to make sure the sniffs work correctly. Use Composer to install the dependencies:

composer install

Then execute the tests:

./vendor/bin/phpunit

Then execute the coding standards checker on Coder itself:

./vendor/bin/phpcs
