thirteenfish / pypubsub

A Python publish-subcribe library (moved here from SourceForge.net where I had it for many years)

News

• January 2019: pypubsub 4.0.3 released! (for those -- and only those -- who use Python >= 3).
• March 2019: pypubsub 3.4.2 released (for those -- and only those -- who use Python 2.7.x).

Overview

Provides a publish-subscribe API to facilitate event-based or message-based architecture in a single-process application. It is pure Python and works on Python 3.3+. It is centered on the notion of a topic; senders publish messages of a given topic, and listeners subscribe to messages of a given topic, all inside the same process. The package also supports a variety of advanced features that facilitate debugging and maintaining topics and messages in larger desktop- or server-based applications.

Install most recent stable with "pip install pypubsub".
