bunch
=====
Bunch is a dictionary that supports attribute-style access, a la JavaScript.
>>> b = Bunch()
>>> b.hello = 'world'
>>> b.hello
'world'
>>> b['hello'] += "!"
>>> b.hello
'world!'
>>> b.foo = Bunch(lol=True)
>>> b.foo.lol
True
>>> b.foo is b['foo']
True
Dictionary Methods
------------------
A Bunch is a subclass of ``dict``; it supports all the methods a ``dict`` does:
>>> b.keys()
['foo', 'hello']
Including ``update()``:
>>> b.update({ 'ponies': 'are pretty!' }, hello=42)
>>> print repr(b)
Bunch(foo=Bunch(lol=True), hello=42, ponies='are pretty!')
As well as iteration:
>>> [ (k,b[k]) for k in b ]
[('ponies', 'are pretty!'), ('foo', Bunch(lol=True)), ('hello', 42)]
And "splats":
>>> "The {knights} who say {ni}!".format(**Bunch(knights='lolcats', ni='can haz'))
'The lolcats who say can haz!'
Serialization
-------------
Bunches happily and transparently serialize to JSON and YAML.
>>> b = Bunch(foo=Bunch(lol=True), hello=42, ponies='are pretty!')
>>> import json
>>> json.dumps(b)
'{"ponies": "are pretty!", "foo": {"lol": true}, "hello": 42}'
If JSON support is present (``json`` or ``simplejson``), ``Bunch`` will have a ``toJSON()`` method which returns the object as a JSON string.
If you have PyYAML_ installed, Bunch attempts to register itself with the various YAML Representers so that Bunches can be transparently dumped and loaded.
>>> b = Bunch(foo=Bunch(lol=True), hello=42, ponies='are pretty!')
>>> import yaml
>>> yaml.dump(b)
'!bunch.Bunch\nfoo: !bunch.Bunch {lol: true}\nhello: 42\nponies: are pretty!\n'
>>> yaml.safe_dump(b)
'foo: {lol: true}\nhello: 42\nponies: are pretty!\n'
In addition, Bunch instances will have a ``toYAML()`` method that returns the YAML string using ``yaml.safe_dump()``. This method also replaces ``__str__`` if present, as I find it far more readable. You can revert back to Python's default use of ``__repr__`` with a simple assignment: ``Bunch.__str__ = Bunch.__repr__``. The Bunch class will also have a static method ``Bunch.fromYAML()``, which loads a Bunch out of a YAML string.
Finally, Bunch converts easily and recursively to (``unbunchify()``, ``Bunch.toDict()``) and from (``bunchify()``, ``Bunch.fromDict()``) a normal ``dict``, making it easy to cleanly serialize them in other formats.
Miscellaneous
-------------
* It is safe to ``import *`` from this module. You'll get: ``Bunch``, ``bunchify``, and ``unbunchify``.
* Ample doctests::
$ python -m bunch.test
$ python -m bunch.test -v | tail -n22
