Lambdabot is an IRC bot used in the #esoteric IRC channel and several other channels on the freenode network. Its most notable feature is that it evaluates Haskell expressions in a sandbox interpreter. int-e currently hosts lambdabot.
Lambdabot's IRC nick is
lambdabot. It can be invoked in channels or private message. Commands are invoked by the
? prefix. Shortcut invocation prefixes are
> , equivalent to
@run, to evaluate a Haskell expression; as well as a few shortcuts that start with
:. In channels, lambdabot prints one line of output for each command, and that one line is truncated to a very short limit. In private message, lambdabot is willing to print longer lines, and you can use the
@more command to get additional lines out output.
Lambdabot is sometimes used to send messages to people in the #esoteric community. The
@tell command sends a message; its argument is an IRC nick followed by a message. The
@ask command also works. The
@messages command reads your messages and immediately forgets them: if you are disconnected from the IRC server just after you issue this command, your messages are lost. A few users don't want to receive lambdabot messages. You can ask who they are by saying
`dontaskdonttelllist to HackEso.
Note that the freenode IRC server also has an unrelated message passing service called MemoServ. The mailboxes for these messages are tied to accounts registered to NickServ, rather than to IRC nicks. Use the
MemoServ HELP IRC command to get information about that service.
