FilterPype is a process-flow pipes-and-filters Python framework.

Project Description

Introduction
============

FilterPype is being used for multi-level data analysis, but could be applied to
many other areas where it is difficult to split up a system into small
independent parts.

Some of its features:

* Advanced algorithms broken down into simple data filter coroutines
* Pipelines constructed from filters in the new FilterPype mini-language
* Domain experts assemble pipelines with no Python knowledge required
* Sub-pipelines and filters linked by automatic pipeline construction
* All standard operations available: branching, joining and looping
* Recursive coroutine pipes allowing calculation of e.g. factorials
* Using it is like writing a synchronous multi-threaded program

Project sponsored by `Flight Data Services`_ and released under the Open
Software License (`OSL-3.0`_).

To Do
=====

* class DataLength(dfb.DataFilter) cf. CountBytes
* Use tank_queue for calculating vertical height change rate
* Make ">>>" redundant, since it adds nothing to the logic of
and just complicates things because of when it is required.

See the **TO-DO** markers in filterpype/*.py for a complete list.
