A set of Magento rules for PHP_CodeSniffer tool.

To use within your Magento 2 project you can use:

composer require --dev magento/magento-coding-standard

Due to security, when installed this way the Magento standard for phpcs cannot be added automatically. You can achieve this by adding the following to your project's composer.json:

"scripts": {
    "post-install-cmd": "vendor/bin/phpcs --config-set installed_paths ../../magento/magento-coding-standard/",
    "post-update-cmd": "vendor/bin/phpcs --config-set installed_paths ../../magento/magento-coding-standard/"
}

You can install Magento Coding Standard by cloning this GitHub repo

$ git clone [email protected]:magento/magento-coding-standard.git
$ cd magento-coding-standard
$ composer install

It is possible also to install a standalone application via Composer

$ composer create-project magento/magento-coding-standard --stability=dev magento-coding-standard

Command should return the list of installed coding standards including Magento2.

$ vendor/bin/phpcs -i

Once installed, you can run phpcs from the command-line to analyse your code MyAwesomeExtension

$ vendor/bin/phpcs --standard=Magento2 app/code/MyAwesomeExtension
