[FEATURE REQUEST]: Auto import and register

[HamadTheIronside]

Problem

Having this folder structure:

• Base.py
• classes
  • child1.py
  • child2.py

At some point, I have to import every single child in some file to register it, and also I have to decorate it. Sometimes it's hard to remember to do this and add the right properties to the children.

Solution suggestion

registery = registerer.Registerer(
    parent_class=BaseClass,
    autoregister=["./classes/*"],
)

This case is suitable for auto-registering. also If I want to unregister, maybe I could add an unregister property to the child class to avoid getting registered automatically.

# classes/child1.py
from base import BaseClass

class Child(BaseClass):
   slug = "child1"

# classes/child2.py
from base import BaseClass

class Child(BaseClass):
   slug = "child1"
   unregister = True

Hi, it's kinda tricky to implement this exact API and also I don't like a few things about it.

The thing I don't like is the fact that child classes are not wrapped with standard @registry.register() function. which makes the registration implicit.

Also I don't think the unregister = True (or anything that is implicitly required to be added to child classes to alter the behavior of registerer) is a good idea.

I prefer this:

# classes/child1.py
from base import BaseClass, registry

@registry.register()
class Child(BaseClass):
   slug = "child1"

Importing this file guarantees that this class will be registered. Now we can think about importing this file automatically...

The thing is tricky to implement is "./classes/*". As you know from our last talk I've written something in c9eee19 commit.

The solution that you propose has also crossed my mind and I've come to a dead end. The inner function (in this case Registerer.__init__) has no idea where you are defining your own registry since it has no idea where your file is located. You need to pass __file__ too.

Despite the fact that something like this is gonna work, I don't like the API:

registery = registerer.Registerer(
    parent_class=BaseClass,
    autoregister=[(__file__, "classes/*")],
)
