A simple PubSub server implementation in Python. Built with Twisted <https://twistedmatrix.com>.

In a virtualenv, run python setup.py install.

Run the PubSub server with pubsubserve (by default, the server listens on localhost:3000).

In an interactive session (I'm using IPython):

In [1]: from pubsub import PubSub

In [2]: def test(**kwargs):
   ...:     print("HELLO %s" % kwargs)
   ...:

In [3]: ps = PubSub()

In [4]: ps.subscribe("hello", test)

In [5]: ps.run()

While this is waiting, in another interactive session:

In [1]: from pubsub import PubSub

In [2]: ps = PubSub()

In [3]: ps.publish("hello", world="WORLD", other="UNIVERSE")

In [4]: ps.run()

In the listener session, HELLO {u'world': u'WORLD', u'other': u'UNIVERSE'} should be visible.
