A simple PHP script to generate the XML necessary for Sonar to detect the Drupal Coder module's sniffs. See: https://drupal.org/node/2082563

 * Generate rules for Drupal Coding Standards Sniffs.
 *
 * SonarQube requires manually-entered PHP CodeSniffer rules if you use anything
 * outside of the standard set of rules. In this case, there are a bunch of
 * Drupal-specific sniffs that we'd like to use.
 *
 * This file takes an array of sniff keys and generates the appropriate XML to
 * pasted into the sonar.phpCodesniffer.customRules.definition setting inside
 * Sonar's Configuration area.
 *
 * After pasting the generated XML, you need to restart the SonarQube server,
 * then enable all the rules you want to use in a quality profile.
 *
 * @see http://docs.codehaus.org/display/SONAR/PHP+Custom+Coding+Rules

I've added some more keys to a fork here if you're interested: https://gist.github.com/Eli-TW/7499132

@Eli-TW - I've incorporated your additions, and added a few dozen more :)

Hey there @geerlingguy , this script is meant to produce a xml ruleset for SonarQube, which is up-to-date with the drupal/coder rules?

@LedzZm - It's been a while since last time I updated it. It may still be a good starting point, but is probably a bit out of date now.

It is out dated. SonarQube is not support the xml ruleset. Now we need to write plugin in java to add custom rules in SonarQube. see below link for more info:
https://docs.sonarqube.org/latest/extend/adding-coding-rules/
https://docs.sonarqube.org/latest/analysis/languages/php/

has anyone wrote a plugin for this?
