README

This Symfony2 bundle provides a way to magically inject dependencies into your services. The dependencies will not be available in the constructor. To use it, you need to complete the following steps:

1. Add the tag magic_injection.injectable_service to the service you wish to inject. The tag takes an optional argument called type, which you can use to group injectable services.
2. Add the tag magic_injection.injection_target to the service which should receive the injected services.
3. Finally, annotate properties with the MagicInjection annotation, which will take an optional type argument that refers to a group of injectable services.

Example usage

• services.yml

  services:
  
    service.that.will.be.injected:
      class: Service\MyServiceA
      tags:
        - { name: magic_injection.injectable_service, type: my_services }
        
    service.that.has.a.dependency:
      class: Service\MyServiceB
      tags:
        - { name: magic_injection.injection_target }

• MyServiceB.php

  class MyServiceB
  {
    /**
     * @MagicInjection(type="my_services")
     * @var \Service\MyServiceA
     */
    private $myServiceA;
  
    public function __construct()
    {
      assert($this->myServiceA === null);
    }
    
    public function foo()
    {
      $this->myServiceA->bar();
    }
  }
