python-csp: Communicating Sequential Processes for Python

Installation

python-csp can be installed using PIP (PIP Installs Python):

$ sudo pip install python-csp

or from a source distribution using setup.py:

$ sudo python setup.py install

Introduction

python-csp adds C.A.R. (Tony) Hoare's Communicating Sequential Processes to Python. A brief example:

>>> @process
... def writer(channel, n):
...      for i in xrange(n):
...              channel.write(i)
...      channel.poison()
...      return
... 
>>> @process
... def reader(channel):
...      while True:
...              print channel.read()
... 
>>> chan = Channel()
>>> Par(reader(chan), writer(chan, 5)).start()
