pymple 0.0.1

A simple Inversion of Control container

Installation

This library is a Python 3.2 library.

Install it via pip for Python 3:

sudo pip3 install pymple

Usage

Pymple nows three types of parameters:

• Values: A value is simply value that is saved and reused for all other factories/singletons

• Singletons: A singleton is a callable that is executed once and the result is saved so future calls to the build method will return the same instance

• Factories: A factory is callable that is executed again everytime it is accessed

from pymple.container import Container

# register simple values
container.register('param', 2)
container.build('param') == 2 # True

# register singletons
class MyClass:
    def __init__(self, value):
        self.value = value

container.register_singleton('MyClass', lambda x: MyClass(x.build('param')))
container.build('MyClass') == container.build('MyClass') # True
container.build('MyClass').value == 2 # True

# register factories (no instance will be saved)
container.register_factory('MyClass', lambda x: MyClass(x.build('param')))
container.build('MyClass') == container.build('MyClass') # False
container.build('MyClass').value == 2 # True
