Recommended Python publish/subscribe/dispatch module ?
- by Eli Bendersky
From PyPubSub:
Pypubsub provides a simple way for
your Python application to decouple
its components: parts of your
application can publish messages (with
or without data) and other parts can
subscribe/receive them. This allows
message "senders" and message
"listeners" to be unaware of each
other:
one doesn't need to import the other
a sender doesn't need to know
"who" gets the messages,
what the listeners will do with the data,
or even if any listener will get the message data.
similarly, listeners don't need to worry about where messages come from.
This is a great tool for implementing
a Model-View-Controller architecture
or any similar architecture that
promotes decoupling of its components.
There seem to be quite a few Python modules for publishing/subscribing floating around the web, from PyPubSub, to PyDispatcher to simple "home-cooked" classes.
Can you recommend a module that works well in most cases ? Which modules have you had positive experience with ? Negative ?
Thanks in advance
