configless 0.1

how to use

you can develop foo function, so IHasFoo interface. and you are providing two variants of foo function. (my.foo and your.foo are these)

## definition
from zope.interface import Interface, implementer
from configless.interfaces import IPlugin

class IHasFoo(Interface):
    def foo():
        pass

@implementer(IHasFoo, IPlugin)
class MyFoo(object):
    @classmethod
    def create_from_setting(cls, settings):
        return cls()

    def foo(self):
        return "my"

@implementer(IHasFoo)
class YourFoo(object):
    @classmethod
    def create_from_setting(cls, settings):
        return cls()

    def foo(self):
        return "your"


## using
from configless import Configurator
config = Configrator()

## install many plugins about `foo`
config.add_plugin("my.foo", MyFoo, categoryname="foo")
config.add_plugin("your.foo", YourFoo, categoryname="foo")

## activate my.foo plugin, then, my.foo is used by plugin about `foo`.
result = config.activate_plugin("my.foo")

## so, configurator has function about result
config.foo.foo() # => "my"

summary

you can provides ‘foo’ function

• define plugin

• install plugin – via config.add_plugin(..)

• activate plugin – via config.activate_plugin(..)
