Glorpen IOC Container

Another Dependency Injection library for Python.

This package has following three guidelines:

• any class configured by Container mechanism should not be modified in any way
• there is no need for external services definition files for Container
• no Container compiling and service tagging - we have introspection and dynamic language for this task

And so this package provides:

• no xml configuration
• no annotations (more cons than pros)
• no changes to services code

Supported design patterns

Service instance can be created by:

• factory service
• calling class object with arguments

Instance options can be altered by:

• constructor arguments
• setters
• calling methods
• using configurator service

Each service has defined scope, service cannot request other service from narrower scope.

Injecting services and parameters

from glorpen.di import Container

class MyParamService(object):
    pass

class MyService(object):
    def __init__(self, obj, text, value):
        super(MyService, self).__init__()
        print("service instance: %s" % obj)
        print("container parameter: %s" % text)
        print("provided value: %s" % value)

c = Container()

c.add_service(MyParamService)
c.add_parameter('my-param', "value from container")
c.add_service(MyService).kwargs(obj__svc=MyParamService, text__param="my-param", value="defined value")

c.get(MyService)

Running snippet will print:

service instance: <__main__.MyParamService object at 0x7f2fef6e9828>
container parameter: value from container
provided value: defined value
