We recently managed to integrate SonarQube and the PHP extension. After some experienced time, we got used to knowing that there are differences between the rules of SonarPHP (Drupal) and the Code Sniffer rules provided by the Drupal community. This is not only settings thing because there are some rules missing. We would like to know if there is a migration path for those rules or if there is a possibility to write the checks in PHP instead of JAVA.
