Version 0.3.0

This is an api breaking release. It changes the api to use inheritance rather than decorators. This provides more clarity as to what is actually happening.

Instead of:

from class_only_design import class_only

@class_only
class MyClass:
    ...

You now do:

from class_only_design import ClassOnly

class MyClass(ClassOnly):
    ...

This release also adds autoname to the namespace class:

>>> from class_only_design import Namespace
>>> from class_only_design import autoname
>>> class NS(Namespace):
>>>     symbolic_handle = autoname

>>> NS.symbolic_handle
    'symbolic_handle'

Version 0.2.0

This adds the namespace decorator, intended for use on class_only classes that just define constant attributes.

For example, given the following class:

from class_only_design import namespace

@namespace
class ColourConstants:
    RED = 'FF0000'
    GREEN = '00FF00'
    BLUE = '0000FF'

The namespace decorator provides the mutability and instanciation protections of class_only, but also:

• makes the class iterable, e.g.:

  list(ColourConstants) # returns ['FF0000', '00FF00', '0000FF']

• adds a special attribute, nameof which returns the name of the class attribute:

  ColourConstants.nameof.RED # returns 'RED'

It also improves the underlying implementation of the class decorators. They no longer modify the class hierarchy.

Add inheritance handling

Class only classes can be inherited, and classes that inherit from class only classes are not instantiable.
