Features

Extends phpmd with rules for Symfony2. Also add extra rules from clean code.

Installation

Composer is used for installation. Add the following lines to your composer.json file:

"require-dev": {
    "mi-schi/phpmd-symfony2": "^2.0"
}

Usage

Create a phpmd.xml file and import the basic rules from phpmd. The example below contains some useful changes. Afterwards you can extend the configuration with rules from this repository.

Basic Rules

<ruleset name="basic-rules"
         xmlns="http://pmd.sf.net/ruleset/1.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://pmd.sf.net/ruleset/1.0.0
                      http://pmd.sf.net/ruleset_xml_schema.xsd"
         xsi:noNamespaceSchemaLocation="http://pmd.sf.net/ruleset_xml_schema.xsd">

    <rule ref="rulesets/cleancode.xml" />
    <rule ref="rulesets/codesize.xml">
        <exclude name="ExcessiveParameterList" />
        <exclude name="ExcessiveMethodLength" />
        <exclude name="ExcessiveClassLength" />
        <exclude name="CyclomaticComplexity" />
    </rule>
    <rule ref="rulesets/codesize.xml/ExcessiveParameterList">
        <properties>
            <property name="minimum" value="4" />
        </properties>
    </rule>
    <rule ref="rulesets/codesize.xml/ExcessiveMethodLength">
        <properties>
            <property name="minimum" value="31" />
            <property name="ignore-whitespace" value="true" />
        </properties>
    </rule>
    <rule ref="rulesets/codesize.xml/ExcessiveClassLength">
        <properties>
            <property name="minimum" value="301" />
            <property name="ignore-whitespace" value="true" />
        </properties>
    </rule>
    <rule ref="rulesets/codesize.xml/CyclomaticComplexity">
        <properties>
            <property name="reportLevel" value="6" />
            <property name="showClassesComplexity" value="true" />
            <property name="showMethodsComplexity" value="true" />
        </properties>
    </rule>
    <rule ref="rulesets/controversial.xml" />
    <rule ref="rulesets/design.xml" />
    <rule ref="rulesets/naming.xml">
        <exclude name="ShortVariable" />
        <exclude name="LongVariable" />
    </rule>
    <rule ref="rulesets/naming.xml/ShortVariable">
        <properties>
            <property name="minimum" value="2" />
        </properties>
    </rule>
    <rule ref="rulesets/naming.xml/LongVariable">
        <properties>
            <property name="maximum" value="30" />
        </properties>
    </rule>
    <rule ref="rulesets/unusedcode.xml" />
</ruleset>

Add extra rules

    <rule ref="../../../../../mi-schi/phpmd-symfony2/Rulesets/cleancode.xml" />
    <rule ref="../../../../../mi-schi/phpmd-symfony2/Rulesets/symfony2.xml" />
    <rule ref="../../../../../mi-schi/phpmd-symfony2/Rulesets/test.xml" />

You can also customize the rules with own properties or use only specific rules. Just take a look in the xml files. It works as the basic ruleset logic.

ToDos

Rule against Train Wreck (getFoo()->getBar()->getMuh()->getMeh())
Rule for high cohesion (member variables are used by a lot of methods)
Rule that a service should never call a controller
Try to avoid "return $this->doSomething() && !$this->doOtherthings()"
