RubyでIRCにメッセージを書き込む

• Rubyでgemを用いてIRCにメッセージを書き込む方法をメモする

各gemによるサンプルコード

• net-irc(0.0.9)
  • botとして書き込み

net-irc-test.rb

gem 'net-irc'
gem 'kronparser'
require 'kronparser'
require 'net/irc'

class TestBot < Net::IRC::Client
  attr_accessor :target_channels

  def initialize(*args)
    @target_channels = []
    super(*args)
  end 

  def on_rpl_welcome(m)
    @target_channels.each do |channel|
      post(JOIN, channel)
    end 
  end 

  def talk(msgs, channels = @target_channels)
    channels.each do |channel|
      if msgs.class == Array
        msgs.each do |msg| post(PRIVMSG, channel, msg) end 
      else
        post(PRIVMSG, channel, msgs)
      end 
    end 
  end 
end

irc = TestBot.new("SERVER",
                  PORT,
                  :nick => "NICK",
                  :user => "USER",
                  :real => "REAL")
irc.target_channels = "#CHANNEL"

KronParser::SimpleProcess.every("40 17 * * 1-5") do
  irc.talk("test")
end

irc.start

• carrier-pigeon(0.6.0)
  • 1行メッセージ書き込みで簡単に使えそう(cronやjenkinsなどでの通知に良いかも)

carrier-pigeon-test.rb

gem "carrier-pigeon"
require "carrier-pigeon"

CarrierPigeon.send(
  :uri => "irc://USER@SERVER:PORT/#CHANNEL",
  :message => "cooooo, coo coo\ncoo",
  :join => true
)

• 2行以上の書き込みもできた

carrier-pigeon-test.rb

gem "carrier-pigeon"
require 'carrier-pigeon'

pigeon = CarrierPigeon.new(:host => "SERVER",
                           :port => PORT,
                           :nick => "USER",
                           :channel => "#CHANNEL",
                           :join => true)
pigeon.message("#CHANNEL", "test")
pigeon.message("#CHANNEL", "hoge")
pigeon.die

• irc-socket(1.0.1)
  • 2行以上のメッセージ書き込みする場合はこれでもいける(cronやjenkinsなどでの通知に良いかも)

irc-socket-test.rb

gem "irc-socket"
require 'irc-socket'

irc = IRCSocket.new("SERVER", PORT)
irc.connect
if irc.connected?
  irc.nick "USER"
  irc.user "USER", 0, "*", "test"

  while line = irc.read
    # Join a channel after MOTD
    if line.split[1] == '376'
      irc.join "#CHANNEL"
      irc.privmsg "#CHANNEL", "hogehoge"
      irc.privmsg "#CHANNEL", "hogehoge"
      irc.part "#CHANNEL"
      break
    end
  end
end
