Project description

Lo4container

The simplest IoC in python

Install

pip install lo4container

Usage

Creating a container is matter of creating a Container instance

from lo4container import Container
container = Container()

Assign value

We can use container as a dictionary, it means you can assign/get value by key, check existing, ...

container['name'] = 'lo4container'
print(container['name'])
# output: 'lo4container'

'name' in container
# return True

If we use lambda function for value, it would execute with container as argument

import datetime
container['timer'] = lambda c: return datetime.datetime.now()

print(container['time'])
# output: 2018-07-07 14:05:59.941780

Each time you get a value by key, lo4container returns a differences instance. If you want the same instance to be returned for all calls, use share method

import datetime
container['timer'] = lambda c: return datetime.datetime.now()
container.share('timer')

print(container['time'])
# output: 2018-07-07 14:05:59.941780

print(container['time'])
# output: 2018-07-07 14:05:59.941780

print(container['time'])
# output: 2018-07-07 14:05:59.941780
# same results for n calls
