Service definition helpers

Helper module adds enhancements for defining services.

Service tags

module_dependency

Indicates a service requires a certain module to be enabled. This is run by \Drupal\helper\Compiler\ModuleDependencyPass.

Usage

services:
  _defaults:
    autowire: true
  my_module.other_module_service:
    class: Drupal\my_module\OtherModuleService
    tags:
      - { name: module_dependency, module: other_module }
  Drupal\my_module\OtherModuleService: '@my_module.other_module_service'

Both the my_module.other_module_service service and its OtherModuleService::class alias will be removed if the other_module is not enabled.
