IRCSupport

IRCSupport provides everything you need to work with the IRC protocol and its widely-used extensions. It is meant to be a building block for higher-level libraries that use IRC (clients or servers). There are a bunch of IRC client/bot libraries for Ruby out there, and they all implement their own stuff for dealing with the IRC protocol. Why not keep it in one place?

Features

• Complete: Includes support for all protocol standards used by modern IRC clients and servers, including:
  • RFC1459
  • RFC2812 & RFC2813
  • CTCP
  • DCC (CHAT, SEND, ACCEPT, RESUME)
  • RPL_ISUPPORT (draft-brocklesby-irc-isupport-03)
  • CAP capabilities extension (draft-mitchell-irc-capabilities-02)
  • mIRC/ECMA-48/RGB color and formatting codes
• Tested: A heavy emphasis is placed on testing the code. It generally has 100% test coverage.
• Flexible: The tools provided by IRCSupport are flexible and modular, and should encourage reuse.

Usage

Here are some examples of using IRCSupport:

require 'ircsupport'

line = ':foo!bar@baz.com PRIVMSG #the_room :Greetings, everyone!'
irc_parser = IRCSupport::Parser.new
msg = irc_parser.parse(line)

msg.channel
# => '#the_room'

msg.sender
# => 'foo!bar@baz'

msg.is_action?
# => false

msg.type
# => :message

IRCSupport::Validations.valid_nick_name?("Foo{}Bar[]")
# => true

IRCSupport::Validations.valid_nick_name?("123FooBar")
# => false

IRCSupport::Numerics.numeric_to_name('005')
# => 'RPL_ISUPPORT'

# any module can also be mixed into your class
include IRCSupport::Numerics
numeric_to_name('001')
# => 'RPL_WELCOME'

See the API documentation for more details.

Components

IRCSupport::Parser

This class is a complete parser for the IRC protocol. It can provide you with rich objects which encapsulate all the information of a message in handy methods.

IRCSupport::Case

A module that provides functions that conversion between various IRC casemappings.

IRCSupport::Encoding

A module that provides functions to encode or decode IRC messages.

IRCSupport::Formatting

A module that provides functions for detecting, stripping, and constructing strings with IRC color and formatting codes.

IRCSupport::Masks

A module that provides functions to deal with IRC masks.

IRCSupport::Modes

A module that provides functions to work with mode strings.

IRCSupport::Numerics

A module that provides functions to look up the names of IRC numerics and vice versa.

IRCSupport::Validations

A module that provides functions to validate various IRC strings.

Supported platforms

IRCSupport works on any Ruby 1.9-compatible VM. As of this writing, Rubinius' encoding support is not complete, so some of the functions in IRCSupport::Encoding will not work on that platform.

Kudos

Those go to the authors of the IRC::Utils Perl module, on which much of this library's functionality is based. Same for the authors of cinch, from which a few functions were borrowed.
