SYNOPSIS
      my $irc = Mojo::IRC->new(
                  nick => 'test123',
                  user => 'my name',

        say $message->{prefix}, " said: ", $message->{params}[1];
      });

DESCRIPTION
    Mojo::IRC is a non-blocking IRC client using Mojo::IOLoop from the
    wonderful Mojolicious framework.

    It features IPv6 and TLS, with additional optional modules:
    IO::Socket::IP and IO::Socket::SSL.

    By default this module will only emit standard IRC events, but by
    settings "parser" to a custom object it will also emit CTCP events.
    Example:

      my $irc = Mojo::IRC->new;
      $irc->parser(Parse::IRC->new(ctcp => 1);
      $irc->on(ctcp_action => sub {
        # ...
      });

    It will also set up some default events: "ctcp_ping", "ctcp_time", and
    "ctcp_version".

    This class inherits from Mojo::EventEmitter.

TESTING
    The module Test::Mojo::IRC is useful if you want to write tests without
    having a running IRC server.

    MOJO_IRC_OFFLINE (from v0.20) is now DEPRECATED in favor of
    Test::Mojo::IRC.

EVENTS
  close
      $self->on(close => sub { my ($self) = @_; });

    Emitted once the connection to the server closes.

  error
      $self->on(error => sub { my ($self, $err) = @_; });

    Emitted once the stream emits an error.

  message
      $self->on(message => sub { my ($self, $msg) = @_; });

    Emitted when a new IRC message arrives. Will dispatch to a default
    handler, which will again emit "err_event_name" "ctcp_event_name" and
    "irc_event_name" below.

    Here is an example $msg:

      {
        command  => "PRIVMSG",
        event    => "privmsg",
        params   => ["#convos", "hey!"],
        prefix   => "jan_henning",
        raw_line => ":jan_henning PRIVMSG #convos :hey",
      }

  err_event_name
    Events that start with "err_" are emitted when there is an IRC response
    that indicates an error. See Mojo::IRC::Events for sample events.

  ctcp_event_name
    Events that start with "ctcp_" are emitted if the "parser" can
    understand CTCP messages, and there is a CTCP response.

      $self->parser(Parse::IRC->new(ctcp => 1);

    See Mojo::IRC::Events for sample events.

  irc_event_name
    Events that start with "irc_" are emitted when there is a normal IRC
    response. See Mojo::IRC::Events for sample events.

ATTRIBUTES
  connect_timeout
      $int = $self->connect_timeout;
      $self = $self->connect_timeout(60);

    Maximum amount of time in seconds establishing a connection may take
    before getting canceled, defaults to the value of the
    "MOJO_IRC_CONNECT_TIMEOUT" environment variable or 30.

  ioloop
    Holds an instance of Mojo::IOLoop.

  local_address
      $str = $self->local_address;
      $self = $self->local_address("10.20.30.40");

    Local address to bind to. See "local_address" in Mojo::IOLoop::Client.

  name
    The name of this IRC client. Defaults to "Mojo IRC".

  nick
    IRC nick name accessor. Default to "user".

  parser
      $self = $self->parser($obj);
      $self = $self->parser(Parse::IRC->new(ctcp => 1));
      $obj = $self->parser;

    Holds a Parse::IRC object by default.

  pass
    Password for authentication

  real_host
    Will be set by "irc_rpl_welcome". Holds the actual hostname of the IRC
    server that we are connected to.

  server
    Server name and, optionally, a port to connect to. Changing this while
    connected to the IRC server will issue a reconnect.

  server_settings
      $hash = $self->server_settings;

    Holds information about the server. See
    <https://github.com/jhthorsen/mojo-irc/blob/master/t/ua-channel-users.t>
    for example data structure.

    Note that this attribute is EXPERIMENTAL and the structure of the values
    it holds.

  user
    IRC username. Defaults to current logged in user or falls back to
    "anonymous".

  tls
      $self->tls(undef) # disable (default)
      $self->tls({}) # enable

    Default is "undef" which disables TLS. Setting this to an empty hash
    will enable TLS and this module will load in default certs. It is also
    possible to set custom cert/key:

      $self->tls({ cert => "/path/to/client.crt", key => ... })

    This can be generated using

      # certtool --generate-privkey --outfile client.key
      # certtool --generate-self-signed --load-privkey client.key --outfile client.crt

METHODS
  connect
      $self = $self->connect(\&callback);

    Will log in to the IRC "server" and call &callback. The &callback will
    be called once connected or if connect fails. The second argument will
    be an error message or empty string on success.

  ctcp
      $str = $self->ctcp(@str);

    This message will quote CTCP messages. Example:

      $self->write(PRIVMSG => nickname => $self->ctcp(TIME => time));

    The code above will write this message to IRC server:

      PRIVMSG nickname :\001TIME 1393006707\001

  disconnect
      $self->disconnect(\&callback);

    Will disconnect form the server and run the callback once it is done.

  new
      $self = Mojo::IRC->new(%attrs);

    Object constructor.

  register_default_event_handlers
      $self->register_default_event_handlers;

    This method sets up the default "DEFAULT EVENT HANDLERS" unless someone
    has already subscribed to the event.

  write
      $self->write(@str, \&callback);

    This method writes a message to the IRC server. @str will be
    concatenated with " " and "\r\n" will be appended. &callback is called
    once the message is delivered over the stream. The second argument to
    the callback will be an error message: Empty string on success and a
    description on error.

DEFAULT EVENT HANDLERS
  ctcp_ping
    Will respond to the sender with the difference in time.

      Ping reply from $sender: 0.53 second(s)

  ctcp_time
    Will respond to the sender with the current localtime. Example:

      TIME Fri Feb 21 18:56:50 2014

    NOTE! The localtime format may change.

  ctcp_version
    Will respond to the sender with:

      VERSION Mojo-IRC $VERSION

    NOTE! Additional information may be added later on.

  irc_nick
    Used to update the "nick" attribute when the nick has changed.

  irc_notice
    Responds to the server with "QUOTE PASS ..." if the notice contains
    "Ident broken...QUOTE PASS...".

  irc_ping
    Responds to the server with "PONG ...".

  irc_rpl_isupport
    Used to populate "server_settings" with information about the server.

  irc_rpl_welcome
    Used to get the hostname of the server. Will also set up automatic PING
    requests to prevent timeout and update the "nick" attribute.

  err_nicknameinuse
    This handler will add "_" to the failed nick before trying to register
    again.
