Editing IRC channel (section)

== Bots ==

There are various bots on the channel. Their names and usage are described here.

=== lambdabot ===

[[Lambdabot]] is both the name of a software package and a bot on the channel. The bot is operated by IRC user <code>int-e</code> and provides many useful services for visitors to the IRC channel. You can interact with it in a private chat or publicly in any channel where it appears (#haskell and a number of others). It is available as a haskell package and can be integrated into ghci. Details on the software are found on a [[Lambdabot|separate wiki page]].

Here is its interface for the IRC user:

lambdabot's commands are prepended by a '@' sign.

=== yahb ===
If lambdabot doesn't cut it for you, there is a bot called yahb which runs your request in an actual GHCi prompt, so you can use IO.

Try e.g. <tt>% readFile "/proc/self/environ"</tt>

=== hackage ===
The hackage bot, when running, provides real-time notifications of new package uploads to [http://hackage.haskell.org Hackage].
