Overview

Description

IRCSocket is an IRC wrapper around a TCPSocket. It implements all of the major commands laid out in RFC 2812. All these commands are available as instance methods of an IRCSocket Object.

Example

irc = IRCSocket.new('irc.freenode.org')
irc.connect

if irc.connected?
  irc.nick "HulkHogan"
  irc.user "Hulk", 0, "*", "I am Hulk Hogan"

  while line = irc.read

    # Join a channel after MOTD
    if line.split[1] == '376'
      irc.join "#mychannel"
    end

    puts "Received: #{line}"
  end
end

Block Form

IRCSocket.new('irc.freenode.org') do |irc|
  irc.nick "SpongeBob"
  irc.user "Spongey", 0, "*", "Square Pants"

  puts irc.read
end

Constructor Details

#initialize(server, port = 6667, ssl = false) ⇒ IRCSocket

Create a new IRCSocket to connect to server on port. Defaults to port 6667. If an optional code block is given, it will be passed an instance of the IRCSocket.

NOTE: Using the block form does not mean the socket will send the applicable QUIT command to leave the IRC server. You must send this yourself.
