#Hircarra
hircarra (plural hircarras)
(historical, India) A messenger, especially one who delivers a personal message.
Hircarra is a Haskell library to write IRC bots. It is meant to be very easy to use and completely extensible. It provides a core on which users can add support for their own IRC messages and replies and handlers. It also comes with a set of handlers (in the hircarra-handlers package) which provide a varied set of functionalities.
Example Usage
To start an IRC with no handlers:
$ cabal repl
*Network.IRC> let botConfig = newBotConfig "irc.freenode.net" 6667 "#hircarra" (Nick "hibot") 130 DEBUG
*Network.IRC> runBot botConfig

Features
Core features:
- Very simple interface. Just create a
BotConfig
and callrunBot
with it. - Automatically handles disconnetions and reconnections.
- Automatically changes nick if not available and recovers the original nick when it becomes available.
- Comes with standard IRC command support built in but users can extend it to add support for custom IRC commands.
- Users can add handlers which can react to IRC commands from channels and from private messages.
Writing Handlers
Let's write a simple echo handler:
$ ghci -package-db=./.cabal-sandbox/x86_64-osx-ghc-7.8.3-packages.conf.d
GHCi, version 7.8.3: http://www.haskell.org/ghc/ :? for help
