shithead-ng

next generation markov chain irc shitposting bot

The problem

The original shithead uses far too much ram and is badly implemented.

The solution

Let's reimplement it and get redis to do all the heavy lifting.

Getting Started

First, set up dependencies. You need a redis server running locally (currently, AUTH and remote servers are not supported, this will be supported in the future) and the necessary perl modules:

# install cpanminus with your package manager of choice (preferred), or install it through cpan:
cpan App::cpanminus
# clone the git repo if you haven't already, then install the perl modules
git clone https://neetco.de/albino/shithead-ng
cpanm --installdeps shithead-ng
# or, to avoid setting up local::lib:
cpanm --sudo --installdeps shithead-ng

Next, you need a brainfile. A brainfile is simply an irc log with all joins, parts, timestamps and nicknames stripped. In other words, it contains only what was said.

# if you have an old brainfile, import it into redis
perl import-brain.pl /home/you/brainfile
# this can take a long time (about ten minutes for me), so be patient

# now, you need a config file
cp config.default.yml config.yml
# edit the values in config.yml to your choosing

Now, just run perl MarkovBot.pl.

Commands

• .shitposting - controls the % of messages the bot will reply to

< user> .shitposting 1.5
< shithead-ng> OK

• .ignore - make the bot totally ignore a user (useful for bots)

< user> .ignore bot
< shithead-ng> Now ignoring bot.

• .unignore - removes a user from the ignore list

< user> .unignore bot
< shithead-ng> No longer ignoring bot.

• .ping - check that shithead-ng is still alive

< user> .ping
< shithead-ng> Pong!
