open source IRC bot written in Lua
TuxBot is an open-source IRC bot written in Lua. It was created to fit the requirements of the #linux channels on irc.oftc.net and irc.esper.net, but it is also used as a helpful bot in some other, non-linux channels on other networks. The bot is able to link linux channels on different networks by relaying messages between them. It is also able to kick flooders and to show the title of HTML pages after someone posted a link in a channel. Furthermore, TuxBot works as a raw multi-network IRC client for the console! There are some other features that are not listed here, too. For example, you can extend TuxBot’s functionality using a simple module system. ;-)
