NAME

       AnyEvent::Impl::EventLib - AnyEvent adaptor for Event::Lib

SYNOPSIS

	  use AnyEvent;
	  use Event::Lib;

	  # this module gets loaded automatically as required

DESCRIPTION

       This module provides transparent support for AnyEvent. You don't have to do anything to make Event work with AnyEvent except by loading
       Event::Lib before creating the first AnyEvent watcher.

       Note: the AnyEvent author has not found recent releases of Event::Lib to be even remotely working (not even the examples from the manpage
       or the testsuite work), so this event backend should be avoided (or somebody should step up and maintain it, hint, hint).

       The Event::Lib module suffers from the same limitations and bugs as libevent, most notably it kills already-installed watchers on a file
       descriptor and it is unable to support fork. These are not fatal issues, and are worked-around by this module, but the Event::Lib perl
       module itself has many additional bugs such as taking references to file handles and callbacks instead of making a copy or freeing still-
       allocated scalars, causing memory corruption and random crashes. Only Tk rivals it in its brokenness.

       This adaptor module employs the same workaround around the watcher problems as Tk and should therefore be avoided. (This was done for
       simplicity, one could in theory work around the problems with lower overhead by managing our own watchers).

       Event::Lib also leaks file handles and memory and tends to just exit on problems.

       It also doesn't work around the Windows bug of not signalling TCP connection failures.

       It also doesn't work with many special devices on Linux (/dev/random works, /dev/urandom fails, /dev/tty works, /dev/null fails and so on).

       Event::Lib does not support idle watchers. They could be emulated using low-priority timers but as the priority range (and availability) is
       not queryable nor guaranteed, and the default priority is likely the lowest one, this module cannot use them.

       Avoid Event::Lib if you can.

NAME

       AnyEvent::IRC - An event based IRC protocol client API

VERSION

       Version 0.96

SYNOPSIS

       Using the simplistic AnyEvent::IRC::Connection:

	  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]!
";
		$c->broadcast;
	     }
	  );

	  $c->wait;

       Using the more sophisticated AnyEvent::IRC::Client:

	  use AnyEvent;
	  use AnyEvent::IRC::Client;

	  my $c = AnyEvent->condvar;

	  my $timer;
	  my $con = new AnyEvent::IRC::Client;

	  $con->reg_cb (registered => sub { print "I'm in!
"; });
	  $con->reg_cb (disconnect => sub { print "I'm out!
"; $c->broadcast });
	  $con->reg_cb (
	     sent => sub {
		my ($con) = @_;

		if ($_[2] eq 'PRIVMSG') {
		   print "Sent message!
";

		   $timer = AnyEvent->timer (
		      after => 1,
		      cb => sub {
			 undef $timer;
			 $con->disconnect ('done')
		      }
		   );
		}
	     }
	  );

	  $con->send_srv (
	     PRIVMSG => 'elmex',
	     "Hello there I'm the cool AnyEvent::IRC test script!"
	  );

	  $con->connect ("localhost", 6667, { nick => 'testbot' });
	  $c->wait;
	  $con->disconnect;

DESCRIPTION

       The AnyEvent::IRC module consists of AnyEvent::IRC::Connection, AnyEvent::IRC::Client and AnyEvent::IRC::Util. AnyEvent::IRC is just a
       module that holds this overview over the other modules.

       AnyEvent::IRC can be viewed as toolbox for handling IRC connections and communications. It won't do everything for you, and you still need
       to know a few details of the IRC protocol.

       AnyEvent::IRC::Client is a more highlevel IRC connection that already processes some messages for you and will generated some events that
       are maybe useful to you. It will also do PING replies for you, manage channels a bit, nicknames and CTCP.

       AnyEvent::IRC::Connection is a lowlevel connection that only connects to the server and will let you send and receive IRC messages.
       AnyEvent::IRC::Connection does not imply any client behaviour, you could also use it to implement an IRC server.

       Note that these modules use AnyEvent as it's IO event subsystem.  You can integrate them into any application with a event system that
       AnyEvent has support for (eg. Gtk2 or Event).

EXAMPLES

       See the samples/ directory for some examples on how to use AnyEvent::IRC.
