NAME

       AnyEvent::IRC::Connection - An IRC connection abstraction

SYNOPSIS

          use AnyEvent;
          use AnyEvent::IRC::Connection;

          my $c = AnyEvent->condvar;

          my $con = new AnyEvent::IRC::Connection;

          $con->connect ("localhost", 6667);

          $con->reg_cb (
             connect => sub {
                my ($con) = @_;
                $con->send_msg (NICK => 'testbot');
                $con->send_msg (USER => 'testbot', '*', '0', 'testbot');
             },
             irc_001 => sub {
                my ($con) = @_;
                print "$_[1]->{prefix} says I'm in the IRC: $_[1]->{params}->[-1]!\n";
                $c->broadcast;
             }
          );

          $c->wait;

DESCRIPTION

       The connection class. Here the actual interesting stuff can be done, such as sending and
       receiving IRC messages. And it also handles TCP connecting and even enabling of TLS.

       Please note that CTCP support is available through the functions "encode_ctcp" and
       "decode_ctcp" provided by AnyEvent::IRC::Util.

   METHODS
       $con = AnyEvent::IRC::Connection->new ()
           This constructor doesn't take any arguments.

           NOTE: You are free to use the hash member "heap" (which contains a hash) to store any
           associated data with this object. For example retry timers or anything else.

           You can also access that member via the "heap" method.

       $con->connect ($host, $port [, $prepcb_or_timeout])
           Tries to open a socket to the host $host and the port $port.  If an error occurred it
           will die (use eval to catch the exception).

           If you want to connect via TLS/SSL you have to call the "enable_ssl" method before to
           enable it.

           $prepcb_or_timeout can either be a callback with the semantics of a prepare callback
           for the function "tcp_connect" in AnyEvent::Socket or a simple number which stands for
           a timeout.

       $con->enable_ssl ()
           This method will enable SSL for new connections that are initiated by "connect".

       $con->disconnect ($reason)
           Unregisters the connection in the main AnyEvent::IRC object, closes the sockets and
           send a 'disconnect' event with $reason as argument.

       $con->is_connected
           Returns true when this connection is connected.  Otherwise false.

       $con->heap ()
           Returns the hash reference stored in the "heap" member, that is local to this
           connection object that lets you store any information you want.

       $con->send_raw ($ircline)
           This method sends $ircline straight to the server without any further processing done.

       $con->send_msg ($command, @params)
           This function sends a message to the server. @ircmsg is the argument list for
           "AnyEvent::IRC::Util::mk_msg (undef, $command, @params)".

   EVENTS
       Following events are emitted by this module and shouldn't be emitted from a module user
       call to "event". See also the documents Object::Event about registering event callbacks.

       connect => $error
           This event is generated when the socket was successfully connected or an error
           occurred while connecting. The error is given as second argument ($error) to the
           callback then.

       disconnect => $reason
           This event will be generated if the connection is somehow terminated.  It will also be
           emitted when "disconnect" is called.  The second argument to the callback is $reason,
           a string that contains a clue about why the connection terminated.

           If you want to reestablish a connection, call "connect" again.

       send => $ircmsg
           Emitted when a message is about to be sent. $ircmsg is an array reference to the
           arguments of "mk_msg" (see AnyEvent::IRC::Util). You may modify the array reference to
           change the message or even intercept it completely by calling "stop_event" (see
           Object::Event API):

              $con->reg_cb (
                 send => sub {
                    my ($con, $ircmsg) = @_;

                    if ($ircmsg->[1] eq 'NOTICE') {
                       $con->stop_event; # prevent any notices from being sent.

                    } elsif ($ircmsg->[1] eq 'PRIVMSG') {
                       $ircmsg->[-1] =~ s/sex/XXX/i; # censor any outgoing private messages.
                    }
                 }
              );

       sent => @ircmsg
           Emitted when a message (@ircmsg) was sent to the server.  @ircmsg are the arguments to
           "AnyEvent::IRC::Util::mk_msg".

       irc_* => $msg
       irc_<lowercase command> => $msg
       read => $msg
           Emitted when a message ($msg) was read from the server.  $msg is the hash reference
           returned by "AnyEvent::IRC::Util::parse_irc_msg";

           Note: '<lowercase command>' stands for the command of the message in (ASCII) lower
           case.

       buffer_empty
           This event is emitted when the write buffer of the underlying connection is empty and
           all data has been given to the kernel. See also "samples/notify" about a usage
           example.

           Please note that this buffer is NOT the queue mentioned in AnyEvent::IRC::Client!
