A generic interface wrapping multiple backends to provide a consistent pubsub API.

Usage

Create a pubsub object:

from anypubsub import create_pubsub
pubsub = create_pubsub('redis')

or create a pubsub object from settings:

from anypubsub import create_pubsub_from_settings
pubsub = create_pubsub_from_settings({'anypubsub.backend': 'redis'}, prefix='anypubsub.')

Subscribe to a channel:

subscriber = pubsub.subscribe('a_channel')

you can also subscribe to multiple channels:

subscriber = pubsub.subscribe('a_channel', 'b_channel')

the subscriber is an iterator object that returns the next published message at each loop increment, and blocks until next message is published.

Publish a message to a channel:

pubsub.publish('a_channel', 'hello world!')

message = next(subscriber)
assert message == 'hello world!'
