Ybot is a customizable bot which was inspired by GitHub's Hubot. Hubot is really cool, but sorry, I don't like JavaScript and I don't know coffescript. Ybot is completely written in Erlang/OTP and you can write plugins in Python, Perl, Ruby, or even in shell.

Building and Running

First of all you must get your own Ybot:

git clone https://github.com/0xAX/Ybot.git

Or download the source file archive: .tar.gz or .zip

After getting source you need to download dependencies and build the source:

./rebar get-deps && ./rebar compile

Then edit the ybot.config configuration file and you can run your Ybot copy:


Run on heroku

  • Get you ybot and configure it.
  • Download heroku
cd Ybot
heroku create your-application-name -s cedar
heroku config:add BUILDPACK_URL=http://github.com/heroku/heroku-buildpack-erlang.git
git push heroku master

Ybot's basic transport is a network interface. Ybot is a chat bot and he spends all of his life chatting. Ybot receives chat messages and execute commands depending on those received messages. At that moment Ybot supports:

  • IRC (+ssl supporting, +private messages supporting).
  • XMPP MUC (+single user chat supporting, +private messages supporting, +ssl supporting).
  • Campfire.
  • HTTP.
  • Gtalk.
  • HipChat.


Ybot is a chat bot and it can execute different commands. Commands are simple chat messages. For example, a chat session:

you: Ybot math 1 + 5
Ybot: Answer: 6

Here are a few simple rules for structuring Ybot plugins.

  • You must address messages to the Ybot.

  • After addressing the bot you specify the command to be executed, for example math or ping. Every command consists from one word.

  • After the command you can specify arguments. Ybot sends all arguments in '' and it turns them into one argument.

  • One command = One plugin. Plugins must live in the plugins directory.

  • Each plugin must have the correct extension, for example:

    • .py
    • .rb
    • .shell

Containing Python, Ruby or shell code.

  • The name of the plugin file must be the same name as the command. For example if we have a Ybot ping command, we must have a plugin named ping.py or ping.rb or ping.shell, etc.

  • Plugin can consist of any code but write the results to STDOUT in the end.

Example Ybot:

Ybot math 3 ^ 2

Here Ybot calls the math plugin with the argument: '3 ^ 2'
