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

Rename configration template

and edit configuration file and you can run your Ybot copy:

Start Ybot node:


Connect to Ybot node console:


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=
echo OTP_R15B01 > .preferred_otp_version
git commit "Select R15B01 as preferred OTP version" .preferred_otp_version
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.
  • HipChat.
  • Flowdock.
  • Skype.
  • Talkerapp.

And also write-only transports:

  • Twitter
  • Channel


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

  • After addressing the bot you specify the command to be executed, for example

    . 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

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

    • .py
    • .rb
    • .shell
  • Erlang/OTP plugin - see example memory plugin

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
    , etc.
  • Plugin can consist of any code but write the results to

    in the end.

Example Ybot:

Ybot math 3 ^ 2

Here Ybot calls the

plugin with the argument: '3 ^ 2'
