  1.     tags: [ 'controller.service_arguments' ]
  3.   Enabel\LayoutBundle\Twig\Extension\LocalesExtension:
  4.     arguments:
  5.       $supportedLocales: '%enabel_layout.supported_locales%'
  6.     tags: [ 'twig.extension' ]
    This file ends with no newline character, or with a different newline character than other files in your project. It won't render properly on a terminal, and it's considered a bad practice.
