Class Namespaces

Well-behaved class namespacing in Python. Inspired by https://erezsh.wordpress.com/2008/06/27/namespaces-lets-do-more-of-those-python-hackery/

Basic Usage

Example code:

import class_namespaces as cn

class MyCls(metaclass=cn.Namespaceable):

    var = 1

    with cn.Namespace() as my_ns:
        var = 2

assert MyCls.var == 1
assert MyCls.my_ns.var == 2

Other things that work:

• Descriptors (methods, classmethods, staticmethods, properties, custom descriptors)

• super()

• Prepopulating Namespaces. The constructor takes the same arguments as a dict.

Things that don’t work:

• Combining with nearly any other metaclass.

• Various ways of putting a Namespace in a Namespace that I didn’t see an obvious way to handle. In particular…

  • There is no way to put an established namespace directly into another namespace.

Things that might work:

• New namespace features in Python 3.6. Current testing is spotty.
