This package is fork of librette/presenter-factory. Unfortunately author of this package is not taking care of this package anymore. But it's very useful. So that's why. And now what:

Nette Framework does have very simple presenter factory which helps you to map namespaces of presenters to the presenter name and vice versa. Unfortunately it's not possible to map two namespaces under one module section:

application:
  mapping:
    Module: App\Presenters\*Presenter

But with this package it is possible:

application:
  mapping:
    Module:
      - App\Presenters\*Presenter
      - Bpp\Controllers\*Controller

In this case Nette is going to look for presenters in two namespaces. This is extremely useful if you have a lot of bundles separated by functionality. For example you have API module with this mapping:

['Api' => 'Ant\ApiModule\Presenters\*Presenter']

Then you have Assets bundle. In this bundle you can setup mapping for presenters under Assets package but related to the API like this:

['Api' => 'Ant\Assets\ApiModule\Presenters\*Presenter']

I found this very useful.
