How to use
from py3njection import inject
from some_package import ClassToInject
class Demo:
@inject
def __init__(self, object_to_use: ClassToInject):
self.dependency = object_to_use
demo = Demo()How does it work ?
The decorator @inject looks for any annotated method/function parameters (return annotation excluded).
It creates a new object from the specified class if no object is already provided.
What if I want a singleton ?
@singleton
class ClassToInject:
passThat’s it ! When @inject sees a class with this decorator, it always uses the same instance.

Some Notes
Unit tests come easy to set up (unless you have too many dependencies, but that would be a code smell, right ?). Just specify mock instances at your object creation. Examples will come later.
This also means the injected object could also have some of its members injected too at their initialization !
