The simplest IoC in python
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
