Tools for flow-based programming
Pipekit connects message processors using pipes. Pipes are just a thin layer on top of Queue objects and 0mq sockets, wrapping them under a common API. The basic idea behind this abstraction is the possibility to transparently replace a pipe implementation with another one, with no code change needed in the producers/consumers.
Pipes simply have an input and an output channel; creating and using them is pretty straightforward:
from pipekit import ThreadPipe # Pipes need to be given a name mypipe = ThreadPipe('my-pipe') mypipe.send('Hello world') print(mypipe.receive()) # Hello world
Pipes are iterables, too:
for msg in mypipe: dosomething(msg)
Need a 0mq-based pipe instead?
from pipekit import ZMQPipe my0mqpipe = ZMQPipe('my-0mq-pipe', address='tcp://*:5555')
from pipekit import Pipe my0mqpipe = Pipe('my-0mq-pipe', impl='zmq', address='tcp://*:5555') print(my0mqpipe) # <pipekit.ZMQPipe object at 0x7fe...>
