maxdavid / nethack-bot.rb
Created March 20, 2014 23:21
IRC bot that plays 'TESC Plays Nethack', a crowdsourced nethack game that takes commands from an IRC channel. 'TESC Plays Nethack' (or TPN) is part of a compsec exercise put on by The Evergreen State College. As a service that needs to be defended by the blue team, these bots add "users" to the narrative.

# arg 1 = irc nick
# args 1< = additional phrases
require 'cinch'
ircnick = ARGV[0]
class NethackCommands
