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-3.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
Composer Installer Plugins
The Coder package (>= 8.2.11) now works with Composer Installer Plugins, that find and register standards whenever packages are installed or updated. To use such a plugin within your project, follow these steps.
composer require --dev dealerdirect/phpcodesniffer-composer-installer
composer require --dev drupal/coder
Now, you will see Drupal and DrupalPractice listed in the available PHP CodeSniffer standards.
vendor/bin/phpcs -i
The same can be done for a Composer global installation.
composer global require dealerdirect/phpcodesniffer-composer-installer
composer global require drupal/coder
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.
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
