      Having worked with - and experienced the 'inconveniences' of - my previous changes (see r6475), I have made further improvements to Doctrine_Cli, and a small change to Doctrine_Task, and have achieved the following.

      • Creating and working with custom tasks is now even easier.
      • Doctrine_Cli is even more powerful since it is now that much easier to extend.
      • Doctrine_Cli is more testable - though there's still room for improvement.

      The enclosed patch was created against 1.2 r6535. I have merged changes committed since r6475 - Jon's changes in r6484.

      Further details:

      Doctrine tasks are always included and 'registered' on startup. By default, loaded custom tasks are then registered.

      Custom tasks need only extend Doctrine_Task - there are no special naming conventions to follow.

      Automatic loading of custom tasks can be disabled by setting the new "autoregister_custom_tasks" config option to FALSE (TRUE is the default).

      The following code includes and registers Doctrine core Tasks, and then registers loaded custom tasks.

      $cli = new Doctrine_Cli();

      The following code includes and registers only Doctrine core Tasks.

      $oCli = new Doctrine_Cli(array('autoregister_custom_tasks' => false));

      The following code includes and registers Doctrine core Tasks, and then registers a custom task loaded after the CLI was instantiated.

      $oCli = new Doctrine_Cli();

      require_once(dirname(_FILE_) . '/TestTask02.php');



      (These code examples can be found in /tests/CliTestCase.)

      Responsibility for naming tasks lies with the tasks themselves. Tasks will still receive a name derived from the fully-qualified (i.e. including namespaces) name of their class, but it is now possible to specify the name at design time - you might want to do this if the default task name would be very long or undesirable for some reason.

      For example:

      namespace fully\qualified;

      class CustomTaskName extends \Doctrine_Task {

      //This task would otherwise be registered as "fully-qualified-custom-task-name"
      public $taskName = 'custom-task-name';

      public function execute () {}

      A CLI can now be instructed to rethrow exceptions. This is very useful if you're running a batch of tasks in a single script and you need processing to stop if one of them fails.

      Simply set the new "rethrow_exceptions" config option to TRUE to enable this behaviour - the default is FALSE.

      For example:

      $oCli = new Doctrine_Cli(array(
      'autoregister_custom_tasks' => false,
      'rethrow_exceptions' => true,


      I think there are still one or two things I'd like to look at, but I wanted to get the bulk of the work in so I don't hold you up.

      Oh, and I'd like to apologise for having moved everything around. I wouldn't normally, but in trying to make sense of things, I found it necessary.
