Codacy PHP_CodeSniffer

This is the docker engine we use at Codacy to have PHP_CodeSniffer support. You can also create a docker to integrate the tool and language of your choice! See the codacy-engine-scala-seed repository for more information.

Usage

You can create the docker by doing:

docker build -t codacy-codesniffer-base .
sbt docker:publishLocal

The docker is ran with the following command:

docker run -it -v $srcDir:/src  <DOCKER_NAME>:<DOCKER_VERSION>

Test

We use the codacy-plugins-test to test our external tools integration. You can follow the instructions there to make sure your tool is working as expected.

Generating the documentation

Requirements:

• phpdoc

  curl -s http://getcomposer.org/installer | php
  php composer install
  composer global require phpdocumentor/phpdocumentor
  export PATH=$PATH:~/.composer/vendor/bin/

Update the versions in composer.json and run:

sbt "runMain codacy.codesniffer.docsgen.GeneratorMain"

This will create updated patterns.json, description.json and the individual documentation Markdown files.

CodeSniffer configuration file

PHP CodeSniffer can be configured by adding a phpcs.xml file to the source code.

Currently, the tool supports this configuration file except from one feature - setting installed_paths: <config name="installed_paths" />

Add new Codesniffer plugin

To add a new plugin to Codesniffer:

1. Add the plugin dependency to require inside composer.json. This depedency must be available on Packagist

2. Add to scala/codacy/codesniffer/docsgen/VersionsHelper.scala the plugin version:

   lazy val newPlugin = properties("pluginNamespace/pluginName").str

3. Implement the plugin documentation parser inside scala/codacy/codesniffer/docsgen/parsers. The parser must extend DocsParser and override the following:

   Name	Description
   override val repositoryURL	Plugin's git repository
   override val checkoutCommit	Commit related to the version on plugin's git repository (you can use the version tag for that)
   override val sniffRegex	Regex to get all Sniffs implementation files
   override def patternIdPartsFor(relativizedFilePath: String): PatternIdParts	Get the pattern id parts from pattern path
   override def descriptionWithDocs(rootDir: File, patternIdParts: PatternIdParts, patternFile: File): (Pattern.Description, Option[String])	Get tuple with small and extended description for pattern

   Example:

   class DrupalCoderDocsParser extends DocsParser {
   
       override val repositoryURL = "https://github.com/pfrenssen/coder.git"
   
       override val checkoutCommit: String = VersionsHelper.drupalCoder
   
       override val sniffRegex: Regex = """.*coder_sniffer\/(Drupal)\/Sniffs\/(.*?)\/(.*?)Sniff.php""".r
   
       override def patternIdPartsFor(relativizedFilePath: String): PatternIdParts = {
           val sniffRegex(drupalCoderVersion, sniffType, patternName) = relativizedFilePath
           PatternIdParts(drupalCoderVersion, sniffType, patternName)
       }
   
       override def descriptionWithDocs(rootDir: File,
                                       patternIdParts: PatternIdParts,
                                       patternFile: File): (Pattern.Description, Option[String]) = {
           (description(patternIdParts, rootDir), this.parseExtendedDescription("Drupal\\Sniffs", patternIdParts, rootDir))
       }
   
       private[this] def description(patternIdParts: PatternIdParts, rootDir: File): Pattern.Description = {
           val caseRegexPattern = """((?<=\p{Ll})\p{Lu}|\p{Lu}(?=\p{Ll}))""".r
           val patternName = caseRegexPattern.replaceAllIn(patternIdParts.patternName, " $1").trim
           val sniffName = caseRegexPattern.replaceAllIn(patternIdParts.sniffType, " $1").trim
           val title = Pattern.Title(s"$sniffName: $patternName")
           val extended = this.parseDescription("Drupal\\Sniffs", patternIdParts, rootDir)
           Pattern.Description(patternIdParts.patternId, title, extended, None, None)
       }
   
   }

4. Add the new parser to the list of parsers inside scala/codacy/codesniffer/docsgen/Generator.scala.

   private[this] val parsers: List[DocsParser] = List(new PHPCSDocsParser(), ...)

5. Generate the documentation
