## Getting Started:
Install the latest stable version with pip:
$ pip install collectionish

## Checkout the docs:
It's best to checkout the [docs](https://collectionish.readthedocs.io). There you'll find detailed
documentation of collectionish's features and lots of examples of how to
use them.

## What's is it?
Python is a wonderful language when it comes to extending inbuilt types
and making things that quack. `collectionish` subscribes to the ideology
that the behaviour of data structures belongs *in* data structures and
that it's better and more graceful to bake the behavior into a type than
to complicate surrounding business logic creating many more wtf moments
and room for bugs to sneak in.
Python's own [collections][https://docs.python.org/library/collections.html] module is a great example. take
`defaultdict`, how many times have you seen something like this?
``` python
pets = [('cat', 'tabby'),
('cat', 'ginger'),
('dog', 'beagle'),
('dog', 'poodle'),
('lizard', 'gecko')
]
pet_dict = {}
for typ, subtyp in pets:
try:
pet_dict[typ].append(subtyp)
except KeyError:
# now we'll need to make an comment to explain...
# if the key doesn't exist pet_dict we make a new
# list containing the pet's subtype
pet_dict[typ] = [subtyp]
```
vs:
``` python
from collections import defaultdict
pet_dict = defaultdict(list)
for typ, subtyp in pets:
pet_dict[typ].append(subtyp)
```
`collectionish` adds some extra collections such like ``AttyDict`` (a
straightforward recursive dot access `dict` ) and ``UniqueTuple`` ( a
tuple of unique items that remembers insertion order). New collections
will be added fairly regularly on the basis that they are generic enough
and useful enough that i find myself repeating them in other projects.
In addition to data structures `collectionish` also provides some
operations for working with data structures (from both standard python
and `collections`) like the recursive getters and setters
``collectionish.ops``.

## Principles:
**useful enough:**
Inspirations for data structures should come from stuff we've written or
needed before at some point.
**generic enough:**
To be extended within reason.
**specific enough:**
To be clear about what things do. We don't aim to make *the* data
structure or stand in for a pandas dataframe that does everything.
**intuitive enough**:
type hinting should generally work the same as it does with parent
types, signatures should not be wildly different, obvious magic methods
or such as `__iter__` should not generally be missing from data types.
**documented enough:**
All public structures and ops should be documented and have doctest
examples so we know its correct and It should be fairly obvious from
somethings name what it is.
**tested more than enough:**
we test with the excellent [hypothesis][https://github.com/HypothesisWorks/hypothesis] library
wherever possible. We do doctests to keep documentation correct.
