injector 0.1

Injector - Python dependency injection framework, inspired by Guice

This framework is also similar to snake-guice, but aims for simplification.

While being inspired by Guice, it does not slavishly replicate its API. Providing a Pythonic API trumps faithful replication.

An Example

Here’s a brief, completely contrived, example from the unit tests:

from injector import Injector, Module, Key, injects, provides

Weight = Key('Weight')
Age = Key('Age')

class MyModule(Module):
    @provides(Weight)
    def provide_weight(self):
        return 50.0

    @provides(Age)
    def provide_age(self):
        return 25

    # TODO(alec) Make provides/inject order independent.
    @provides(str)
    @inject(age=Age, weight=Weight)
    def provide_description(self, age, weight):
        return 'Bob is %d and weighs %0.1fkg' % (age, weight)

assert_equal(Injector(MyModule()).get(str), 'Bob is 25 and weighs 50.0kg')
