Project Description
==========
Succession
==========

|build-status| |coverage|

A python library providing a useful abstraction for recording state transitions, compressing them, and distributing to multiple listeners.



Usage
=====

Compression
-----------

The :class:`Succession` class provides a way to reduce long chains of updates
down to a reduced chain with the same effect.

For example, assume that you only care about the sum of the numbers pushed to a
succession, and that it's fine to replace all of the numbers from before you started
listening with the current total. You can do something like the following:

>>> succession = Succession(compress=lambda items: [sum(items)])
<succession.Succession object at 0x7f5a65a10518>
>>> from_start = succession.iter()
>>> for i in [1, 2, 3, 4, 5]:
... succession.push(i)
... succession.close()
>>> from_end = succession.iter()
>>> list(from_start)
[1, 2, 3, 4, 5])
>>> list(from_end)
[15]

Iterators forked earlier will not miss any transitions added from the time they
were created. Compression is only applied to transitions before the fork.


Installation
============
Recommended method is to use the version from `pypi`_

.. code::

pip install succession
