Remove dependency of Zend\ModuleManager on Zend\Mvc

[RalfEggert]

The Zend\ModuleManager has a hard dependency on Zend\Mvc within these two listeners:

• Zend\ModuleManager\Listener\OnBootstrapListener
• Zend\ModuleManager\Listener\LocatorRegistrationListener

Both listeners use the MvcEvent::EVENT_BOOTSTRAP constant. If you want to use the ModuleManager standalone, for example within a Console application based on https://github.com/zfcampus/zf-console, you need to install Zend\Mvc and all of its dependencies.

It would be quite helpful if this hard dependency could be removed though I have no idea how to do this.

I looked into it again and thought that I found a solution. We could use the ListenerOptions to inject the MvcEvent::EVENT_BOOTSTRAP constant and use this constant within the two listeners. But that would mean to add the constant to Zend\ModuleManager\Listener\ListenerOptions somehow which does not really solve the issue.

Has anyone any other idea?

Is the constant the only dependency? Because we can get rid of that eventually...

[RalfEggert]

Yes, its the only dependency to the Zend\Mvc component:

https://github.com/zendframework/zf2/blob/master/library/Zend/ModuleManager/Listener/LocatorRegistrationListener.php#L70

https://github.com/zendframework/zf2/blob/master/library/Zend/ModuleManager/Listener/LocatorRegistrationListener.php#L86

https://github.com/zendframework/zf2/blob/master/library/Zend/ModuleManager/Listener/OnBootstrapListener.php#L37

We can safely hardcode the string there, then (or move it to a reference to a constant that is internal to the ModuleManager component).

Tried to solve it by the PR #7060

Would that be ok?

Handled in #7060
