1.1 Interacting with the Bot
Almost all commands start with an @. A command is invoked by writing @<command-name> [args]. For example @type map will make lambdabot respond with (a -> b) -> [a] -> [b].
The special command @eval has a synonym >, meaning that you can evaluate Haskell expressions dynamically with:
> map (+1) [1..10] [2,3,4,5,6,7,8,9,10,11]
Good commands to know are @help and @listcommands.
Lambdabot is an open-source application. The @version command provides details on where to find the source. Anyone may write a plugin. To submit a plugin, use darcs send to submit it to the bot's current maintainer.
For more info, see the sources or ask the bot itself. If you have any questions about Lambdabot, ask on the #haskell irc channel.
