A small but powerful IRC bot


  1. Add kaguya to your list of dependencies in mix.exs:
def deps do
  [{:kaguya, "~> x.y.z"}]
  1. Run mix deps.get

  2. Ensure kaguya is started before your application:

def application do
  [applications: [:kaguya]]
  1. Configure kaguya in config.exs:
config :kaguya,
  server: "my.irc.server",
  port: 6666,
  bot_name: "kaguya",
  channels: ["#kaguya"]


By default Kaguya won't do much. This is an example of a module which will perform a few simple commands:

defmodule Kaguya.Module.Simple do
  use Kaguya.Module, "simple"

  handle "PRIVMSG" do
    match ["!ping", "!p"], :pingHandler
    match "hi", :hiHandler
    match "!say ~message", :sayHandler

  defh pingHandler, do: reply "pong!"
  defh hiHandler(%{user: %{nick: nick}}), do: reply "hi #{nick}!"
  defh sayHandler(%{"message" => response}), do: reply response

This module defines four commands to be handled:

  • !ping and !p are aliased to the same handler, which has the bot respond pong!.
  • hi will cause the bot to reply saying "hi" with the persons' nick
  • !say [some message] will have the bot echo the message the user gave.

The handler macro can accept up to two different parameters, a map which destructures a message struct, and a map which destructures a match from a command.

You can find a more full featured example in example/basic.ex.
