Checking Code Style

Before opening a pull request, you should check your code style. If you are using the Vagrant, you can run phpcs within the Drupal installation directory (on the Vagrant, that is /var/www/html/drupal) or from within the web directory (/var/www/html/drupal/web) as follows:

  • from within Drupal's root directory: ./vendor/bin/phpcs --standard=./vendor/drupal/coder/coder_sniffer/Drupal modules/contrib/my_module, where modules/contrib/my_module is the relative or full path to the PHP file you want to check.
  • from within Drupal's web directory: ../vendor/bin/phpcs --standard=../vendor/drupal/coder/coder_sniffer/Drupal yourfile, where yourfile is the relative or full path to the PHP file you want to check.

In both cases:

  • the path to the coding standard file can be relative to where you are running it from, e.g. when in web: --standard=../vendor/drupal/coder/coder_sniffer/Drupal
  • you can specify a single file to check, or a directory path; in the latter case, all files in that directory will be checked.

Islandora runs phpcs in its Github continuous integration environment, and there, it specifies which files to ignore and which files to check. It is a good idea for developers to specify the same options when running phpcs locally, prior to opening a pull request. For example (running phpcs from the within Drupal's web directory), you should use the following --ignore and --extensions options:

../vendor/bin/phpcs --standard=../vendor/drupal/coder/coder_sniffer/Drupal --ignore=*.md --extensions=php,module,inc,install,test,profile,theme,css,info modules/contrib/my_module
