configurator

Project description

configless is tiny small configurator, inspired by pyramid’s configurator. but this is silly not comprehensive.

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(..)
