Little Dependency Injection Container

Project description

# Simple Little Dependency Injection Container

[![Build Status](https://secure.travis-ci.org/aventurella/pydi.png?branch=master)](http://travis-ci.org/aventurella/pydi)

## Usage:

```python
from pydi import Container

class DogService(object):
def __init__(self, dep):
self.dep = dep

def action(self):
self.dep.action()

class FooService(object):

def __init__(self, dep1, dep2):
self.dep1 = dep1
self.dep2 = dep2

def action1(self):
self.dep1.action()

def action2(self):
self.dep2.action()

class Bar(object):

def action(self):
print('bar')

class Baz(object):

def __init__(self, option):
self.option = option

def action(self):
print('baz!!!', self.option)

class Lucy(object):

def action(self):
print("I'm a dog!")


container = Container()

# shared must be called last. It will reuse an instance
container.register(FooService).depends(Bar).depends(Baz, option="Hello World!").shared()

# without shared, a new instance will be created each time
container.register(DogService).depends(Lucy)

# could also container['FoOSeRViCE']()
obj = container.FooService()
obj.action1()
obj.action2()

print('+-------------+')

# could also container['fooservice']()
obj2 = container.FooService()
obj2.action1()


print('+-------------+')

obj3 = container.FooService()
obj3.action1()
```
