Question

I am working with a plugin in symfony 1.4, and would like to add a listener for a task from another plugin. When the user does php symfony doctrine:build I want my plugin to run a task of its own. Where/how do I register the listener? I did not have any success with http://www.symfony-project.org/gentle-introduction/1_4/en/17-Extending-Symfony

Thank you!

Actually you can hook your code to any symfony task. Have a look at sfBaseTask::doRun method. Any task, when is executed, emits 2 events: command.pre_command and command.post_command.

Create a class to store you code, for example:

class toolkitEvents
{
  static public function commandPostEventHook(sfEvent $event)
  {
    $task = $event->getSubject();
    if ($task->getFullName() === 'doctrine:build')
    { 
     //do stuff or call another task
    }
}

and connect this method to a dispatcher when initializing your plugin:

class yourPluginConfiguration extends sfPluginConfiguration
{
  public function initialize()
  {
    $this->dispatcher->connect('command.post_command', array('toolkitEvents', 'commandPostEventHook'));  
  }
