Supybot is a clearly-written Python IRC framework and bot, intended to be both easily extensible and very flexible. Several modules are included by default. Numerous plugins are already written, including Google, Factoids, RSS, Quotes, and Relay.
Plugins and their commands achieve greater utility via command nesting, something that no other IRC bot does. The user database is based on "capabilities" rather than obscure flags or arbitrary numeric "userlevels", giving the bot flexibility and fine-grained control (think ACLs vs. standard *nix permissions).
Developing your own additions to the bot is simple with the base classes provided; writing a new command for the bot is as simple as writing a function. Unlike many other IRC frameworks, this simplicity is achieved at no cost to generality, which lets new programmers and old programmers alike feel at home in the framework.
Main features:
- Supybot is actively developed.
- Supybot offers nested commands.
- Supybot has a powerful and flexible capability system for handling security.
- Supybot includes many plugins , and has many more ripe for the picking on this very website.
- Supybot supports multiple servers.
- Supybot supports multiple channels.
- Supybot is user-friendly.
- Supybot is developer-friendly.
- Supybot is stable.
- The stability of a Supybot is only limited by the uptime of the host it runs on. Multi-month uptimes are the norm, rather than the exception.
Enhancements:
- A few of the more important changes are changing the default network driver from Twisted to Socket and fixing the crash bug with the Karma plugin.
