README

Abstract

This project implements a set of rules for use with PHP CodeSniffer.

See MediaWiki conventions on our wiki for a detailed description of the coding conventions that are validated by these rules. :-)

How to install

1. Create a composer.json which adds this project as a dependency:

   {
   	"require-dev": {
   		"mediawiki/mediawiki-codesniffer": "40.0.1"
   	},
   	"scripts": {
   		"test": [
   			"phpcs -p -s"
   		],
   		"fix": "phpcbf"
   	}
   }
   

2. Create a .phpcs.xml with our configuration:

   <?xml version="1.0"?>
   <ruleset>
   	<rule ref="./vendor/mediawiki/mediawiki-codesniffer/MediaWiki"/>
   	<file>.</file>
   	<arg name="bootstrap" value="./vendor/mediawiki/mediawiki-codesniffer/utils/bootstrap-ci.php"/>
   	<arg name="extensions" value="php"/>
   	<arg name="encoding" value="UTF-8"/>
   </ruleset>
   

3. Install: composer update

4. Run: composer test

5. Run: composer fix to auto-fix some of the errors, others might need manual intervention.

6. Commit!

Note that for most MediaWiki projects, we'd also recommend adding a PHP linter to your composer.json – see the full documentation for more details.

Configuration

Some of the sniffs provided by this codesniffer standard allow you to configure details of how they work.

• MediaWiki.Classes.FullQualifiedClassName: This sniff is disabled by default.

  <rule ref="MediaWiki.Classes.FullQualifiedClassName">
      <severity>5</severity>
      <properties>
          <property name="allowMainNamespace" value="false" />
          <property name="allowInheritance" value="false" />
          <property name="allowFunctions" value="false" />
      </properties>
  </rule>
  

• MediaWiki.Usage.ExtendClassUsage: This sniff lets you exclude globals from being reported by the sniff, in case they cannot be replaced with a Config::getConfig() call. Examples that are already in the list include $wgTitle and $wgUser.

  <rule ref="MediaWiki.Usage.ExtendClassUsage">
      <properties>
          <property name="nonConfigGlobals[]" type="array" value="$wg...,$wg..." />
      </properties>
  </rule>
  

• MediaWiki.Commenting.ClassLevelLicense: This sniff does nothing by default.

  <rule ref="MediaWiki.Commenting.ClassLevelLicense">
      <properties>
          <property name="license" value="GPL-2.0-or-later" />
      </properties>
  </rule>
  

• MediaWiki.NamingConventions.PrefixedGlobalFunctions: This sniff lets you define a list of ignored global functions and a list of allowed prefixes. By default the only allowed prefix is 'wf', corresponding to the global function wf...().

  <rule ref="MediaWiki.NamingConventions.PrefixedGlobalFunctions">
      <properties>
          <property name="allowedPrefixes[]" value="wf,..." />
          <property name="ignoreList[]" value="...,..." />
      </properties>
  </rule>
  

• MediaWiki.NamingConventions.ValidGlobalName: This sniff lets you define a list of ignored globals and a list of allowed prefixes. By default the only allowed prefix is 'wg', for global variables $wg....

  <rule ref="MediaWiki.NamingConventions.ValidGlobalName">
      <properties>
          <property name="allowedPrefixes[]" value="wg,..." />
          <property name="ignoreList[]" value="...,..." />
      </properties>
  </rule>
  

• MediaWiki.Arrays.TrailingComma: This sniff lets you enforce that multi-line arrays have trailing commas, which makes Git diffs nicer. It can also enforce that single-line arrays have no trailing comma. By default, it does nothing.

  <rule ref="MediaWiki.Arrays.TrailingComma">
      <properties>
          <property name="singleLine" value="false" />
          <property name="multiLine" value="true" />
      </properties>
  </rule>
