supermutes 0.1.3

A collection of super mutables

This project defines two kinds of mutables.

dot

The dot module contains classes that allow dot-notation to be used for when accessing a list or dict object.

eg:

>>  from supermutes.dot import dotify
>>  d = dotify({'a':[1, 2, 3, 4, 5], 'b': {'c': 5}})
>>  d.a._0
1
>>  d.b.c
5
>>  d.c = {'f': 9}
>>  d.c.f
9

readonly

The readonly module contains classes that transform dict and list objects into ones that cannot have any values changed on them.

eg:

>>  from supermutes.readonly import readonly
>>  r = readonly({'a':[1, 2, 3, 4, 5], 'b': {'c': 5}})
>>  r
{'a': [1, 2, 3, 4, 5], 'b': {'c': 5}}
>>  r['a'].append(5)
supermutes.readonly.ReadOnlyClassException: Cannot write to object.
>> r['b']['d'] = 6
supermutes.readonly.ReadOnlyClassException: Cannot write to object.

Creating Sub Classes

Upon declaration of a sub class of any of the supermutes, that class will be set as the defacto class for recursively changing data sets.

To reset the classes back to the original set, use the reset_mapping method inside the module

eg:

>>> from supermutes.dot import DotDict, DotList, reset_mapping
>>> class MySubClass(DotDict): pass
>>> d = MySubClass({'a': {'b': {'c': 3}}})
>>> d.a.b
{'c': 3}
>>> d.a.b.__class__
<class '__main__.MySubClass'>
>>> f = DotList([1, {}])
>>> f[1].__class__
<class '__main__.MySubClass'>
>>> reset_mapping()
>>> f = DotList([1, {}])
>>> f[1].__class__
<class 'supermutes.dot.DotDict'>
