PHP_CodeSniffer Standards Composer Installer Plugin

This composer installer plugin allows for easy installation of PHP_CodeSniffer coding standards (rulesets).

No more symbolic linking of directories, checking out repositories on specific locations or changing the phpcs configuration.

Note: This plugin is compatible with both version 2.x and 3.x of PHP_CodeSniffer

Usage

Installation can be done with composer, by requiring this package as a development dependency:

composer require --dev dealerdirect/phpcodesniffer-composer-installer

That's it.

How it works

Basically, this plugin executes the following steps:

• This plugin search for phpcodesniffer-standard packages in all of your currently installed Composer packages.
• Matching packages and the project itself are scanned for PHP_CodeSniffer rulesets.
• The plugin will call PHP_CodeSniffer and configure the installed_paths option.

Example project

The following is an example Composer project and has included multiple phpcodesniffer-standard packages.

{
    "name": "dealerdirect/example-project",
    "description": "Just an example project",
    "type": "project",
    "require": {},
    "require-dev": {
        "dealerdirect/phpcodesniffer-composer-installer": "*",
        "object-calisthenics/phpcs-calisthenics-rules": "*",
        "phpcompatibility/php-compatibility": "*",
        "wp-coding-standards/wpcs": "*"
    }
}

After running composer install PHP_CodeSniffer just works:

$ ./vendor/bin/phpcs -i
The installed coding standards are MySource, PEAR, PSR1, PSR2, Squiz, Zend, PHPCompatibility, WordPress,
WordPress-Core, WordPress-Docs, WordPress-Extra and WordPress-VIP

Calling the plugin directly

In some circumstances, it is desirable to call this plugin's functionality directly. For instance, during development or in CI environments.

As the plugin requires Composer to work, direct calls need to be wired through a project's composer.json.

This is done by adding a call to the Plugin::run function in the script section of the composer.json:

{
    "scripts": {
        "install-codestandards": [
            "Dealerdirect\\Composer\\Plugin\\Installers\\PHPCodeSniffer\\Plugin::run"
        ]
    }
}

The command can then be called using composer run-script install-codestandards or referenced from other script configurations, as follows:

{
    "scripts": {
        "install-codestandards": [
            "Dealerdirect\\Composer\\Plugin\\Installers\\PHPCodeSniffer\\Plugin::run"
        ],
        "post-install-cmd": [
            "@install-codestandards"
        ]
    }
}

For more details about Composer scripts, please refer to the section on scripts in the Composer manual.

Caveats

When this plugin is installed globally, composer will load the global plugin rather than the one from the local repository. Despite this behavior being documented in the composer manual, it could potentially confuse as an other version of the plugin could be run and not the one specified by the project.

Developing Coding Standards

Coding standard can be developed normally, as documented by PHP_CodeSniffer, in the Coding Standard Tutorial.

Create a composer package of your coding standard by adding a composer.json file.

{
  "name" : "acme/phpcodesniffer-our-standards",
  "description" : "Package contains all coding standards of the Acme company",
  "require" : {
    "php" : ">=5.4.0,<8.0.0-dev",
    "squizlabs/php_codesniffer" : "^2.0"
  },
  "type" : "phpcodesniffer-standard"
}

Requirements:

• The repository may contain one or more standards.
• Each standard can have a separate directory no deeper than 3 levels from the repository root.
• The package type must be phpcodesniffer-standard. Without this, the plugin will not trigger.
