ultraimport: Dependency Injection Example

How To Run?

 python ./run.py
injected logger: worker.py is doing some work

In our run.py we import worker.py and while doing that inject our own log() method as logx() into worker.py:

import ultraimport

def log(msg):
    print('injected logger:', msg)

ultraimport('__dir__/worker.py', package='somepackage', inject={ 'logx': log })

logger.py (actually not used):

def log(msg):
    print('log:', msg)

print('logger.py was imported')

worker.py:

# Note: logx() method will be injected
if not 'logx' in globals():
    from logger import log as logx

logx('worker.py is doing some work')
