=head1 NAME

Net::XMPP2 - An implementation of the XMPP Protocol

=head1 VERSION

Version 0.04

=cut

our $VERSION = '0.04';

=head1 SYNOPSIS

   use Net::XMPP2::Connection;

or:

   use Net::XMPP2::IM::Connection;

or:

   use Net::XMPP2::Client;

=head1 DESCRIPTION

This is the head module of the L<Net::XMPP2> XMPP client protocol (as described in
RFC 3920 and RFC 3921) framework.

L<Net::XMPP2::Connection> is a RFC 3920 conformant "XML" stream implementation
for clients, which handles TCP connect up to the resource binding. And provides
low level access to the XML nodes on the XML stream along with some high
level methods to send the predefined XML stanzas.

L<Net::XMPP2::IM::Connection> is a more high level module, which is derived
from L<Net::XMPP2::Connection>. It handles all the instant messaging client
functionality described in RFC 3921.

L<Net::XMPP2::Client> is a multi account client class. It manages connections
to multiple XMPP accounts and tries to offer a nice high level interface
to XMPP communication.

For a list of L</Supported extensions> see below.

There are also other modules in this distribution, for example:
L<Net::XMPP2::Util>, L<Net::XMPP2::Writer>, L<Net::XMPP2::Parser> and those I
forgot :-) Those modules might be helpful and/or required if you want to use
this framework for XMPP.

See also L<Net::XMPP2::Writer> for a discussion about the brokeness of XML in the XMPP
specification.

If you have any questions or seek for help look below under L</SUPPORT>.

=head1 REQUIREMENTS

One of the major drawbacks I see for Net::XMPP2 is the long list of required
modules to make it work.

=over 4

=item L<AnyEvent>

For the I/O events and timers.

=item L<XML::Writer>

For writing "XML".

=item L<XML::Parser::Expat>

For parsing partial "XML" stuff.

=item L<MIME::Base64>

For SASL authentication

=item L<Authen::SASL>

For SASL authentication

=item L<Net::LibIDN>

For stringprep profiles to handle JIDs.

=item L<Net::SSLeay>

For SSL connections.

=item L<Net::DNS>

For SRV RR lookups.

=item L<Digest::SHA1>

For component authentication.

=back

And yes, all these are essential for XMPP communication. Even though 'instant
messaging' and 'presence' is a quite simple problem XMPP somehow was successful
at making the task complicated enough to keep me busy for a long time.  But all
of that time wasn't only for the technology required to get it started, mostly
it was for all the quirks, hacks and badly applied "XML" in the protocol which
complicated the matter.

=head1 RELEASE NOTES

Here are some notes to the releases (release of this version is at top):

=head2 Version

=over 4

=item * 0.04

After realizing that in band registration in L<Net::XMPP2::Ext> was already
in in version 0.03 I finally had to implement it.

While implementing in band registration I implemented XEP-0066: Out of Band Data.
You can now receive and send URLs from and to others. See also L<Net::XMPP2::Ext::OOB>.

I also fixed some bugs in L<Net::XMPP2::Ext::Disco>.

=item * 0.03

This release adds new events for attaching information to "XML" stanzas that
are in transmission to the server. See also the events C<send_*_hook> in
L<Net::XMPP2::Connection>.

The event callbacks als don't have to return a true value anymore. What the
return values do depends on the event now.

The highlight of this release is the implementation of XEP-0114, the Jabber
Component Protocol.

It's possible to get a DOM tree from a L<Net::XMPP2::Node> now and also to
receive the original parsed "XML" from it, which should enable full access to
the "XML" data that was received. This also allows easy integration with other
XML Perl modules.

You can also set the initial priority of the presence in
L<Net::XMPP2::IM::Connection> now.

Please consult the Changes file for greater detail about bugfixes and new
features.

=item * 0.02

This release adds lots of small improvements to the API (mostly new events),
and also some bugfixes here and there. The release also comes with some
new examples, you might want to take a look at the L</EXAMPLES> section.

As a highlight I also present the implementation of XEP-0004 (Data Forms), see also
L<Net::XMPP2::Ext> for a description.

I also added some convenience functions to L<Net::XMPP2::Util>, for example
C<simxml> which simplifies the generation of XMPP-like "XML".

=item * 0.01

This release has beta status. The code is already used daily in my client
and I keep looking out for bugs. If you find undocumented, missing or faulty
code/methods please drop me a mail! See also L</BUGS> below.

Potential edges when using this module: sparely documented methods, missing
functionality and generally bugs bugs and bugs. Even though this module is in
daily usage there are still lots of cases I might have missed.

For the next release I'm planning to provide more examples in the documentation
and/or samples/ directory, along with bugfixes and enhancements along with some
todo items killed from the TODO file.

=back

=head2 TODO

There are still lots of items on the TODO list (see also the TODO file
in the distribution of Net::XMPP2).

=head1 Why (yet) another XMPP module?

The main outstanding feature of this module in comparison to the other XMPP
(aka Jabber) modules out there is the support for L<AnyEvent>. L<AnyEvent>
permits you to use this module together with other I/O event based programs and
libraries (ie. L<Gtk2> or L<Event>).

The other modules could often only be integrated in those applications or
libraries by using threads. I decided to write this module because I think CPAN
lacks an event based XMPP module. Threads are unfortunately not an alternative
in Perl at the moment due the limited threading functionality they provide and
the global speed hit. I also think that a simple event based I/O framework
might be a bit easier to handle than threads.

Another thing was that I didn't like the APIs of the other modules. In L<Net::XMPP2>
I try to provide low level modules for speaking XMPP as defined in RFC 3920 and RFC 3921
(see also L<Net::XMPP2::Connection> and L<Net::XMPP2::IM::Connection>). But I also
try to provide a high level API for easier usage for instant messaging tasks
and clients (eg. L<Net::XMPP2::Client>).

=head1 A note about TLS

This module also supports TLS, as the specification of XMPP requires an
implementation to support TLS.

Maybe there are still some bugs in the handling of TLS in L<Net::XMPP2::Connection>.
So keep an eye on TLS with this module. If you encounter any problems it would be
very helpful if you could debug them or at least send me a detailed report on how
to reproduce the problem.

(As I use this module myself I don't expect TLS to be completly broken, but it
might break under different circumstances than I have here.  Those
circumstances might be a different load of data pumped through the TLS
connection.)

I mainly expect problems where available data isn't properly read from the socket
or written to it. You might want to take a look at the C<debug_send> and C<debug_recv>
events in L<Net::XMPP2::Connection>.

=head1 Supported extensions

See L<Net::XMPP2::Ext> for a list.

=head1 EXAMPLES

Following examples are included in this distribution:

=over 4

=item B<samples/simple_example_1>

This example script just connects to a server and sends a message and
also displays incoming messages on stdout.

=item B<samples/devcl/devcl>

This is a more advanced 'example'. It requires you to have L<Gtk2>
installed. It's mostly used by the author to implement proof-of-concepts.
Currently you start the client like this:

   ../Net-XMPP2/samples/devcl/# perl ./devcl <jid> <password>

The client's main window displays a protocol dump and there is currently
a service discovery browser implemented.

This might be a valuable source if you look for more real-world
applications of L<Net::XMPP2>.

=item B<samples/conference_lister>

See below.

=item B<samples/room_lister>

See below.

=item B<samples/room_lister_stat>

These three scripts implements a global room scan.  C<conference_lister> takes
a list of servers (the file is called C<servers.xml> which has the same format as
the xml file at L<http://www.jabber.org/servers.xml>). It then scans all
servers for chat room services and lists them into a file C<conferences.stor>,
which is a L<Storable> dump.

C<room_lister> then reads that file and queries all services for rooms, and then
all rooms for their occupants. The output file is C<room_data.stor>, also a L<Storable>
dump, which in turn can be read with C<room_lister_stat>, which transform
the data structures into something human readable.

These scripts are a bit hacky and quite complicated, but maybe it's of any
value for someone. You might note L<samples/EVQ.pm> which is a module that
handles request-throttling (You don't want to flood the server and risk
getting the admins attention :).

=item B<samples/simple_component>

This is a (basic) skeleton for a jabber component.

=item B<samples/simple_oob_retriever>

This is a simple out of band file transfer receiver bot.  It uses C<curl> to
fetch the files and also has the sample functionality of sending a file url for
someone who sends the bot a 'send <filename>' message.

=item B<samples/simple_register_example>

This is a example script which allows you to register, unregister and change
your password for accounts. Execute it without arguments for more details.

=back

For others, which the author might forgot or didn't want to
list here see the C<samples/> directory.

More examples will be included in later releases, please feel free to ask the
L</AUTHOR> if you have any questions about the API. There is also an IRC
channel, see L</SUPPORT>.

=head1 BUGS

Please note that I'm currently (July 2007) the only developer on this project
and I'm very busy with my studies in Computer Science in Summer 2007. If you
want to ease my workload or want timely releases, please send me patches instead
of bug reports or feature requests. I won't forget the reports or requests if
you can't or didn't send patches, but I can't gurantee immediate response.
But I will of course try to fix/implement them as soon as possible!

Also try to be as precise as possible with bug reports, if you can't send a
patch, it would be best if you find out which code doesn't work and tell me
why.

Please report any bugs or feature requests to
C<bug-net-xmpp2 at rt.cpan.org>, or through the web interface at
L<http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Net-XMPP2>.
I will be notified and then you'll automatically be notified of progress on
your bug as I make changes.

=head1 ACKNOWLEDGEMENTS

Thanks to the XSF for the development of an open instant messaging protocol (even though it uses "XML").

And thanks to all people who had to listen to my desperate curses about the
brokenness/braindeadness of XMPP. Without you I would've never brought this
module to a usable state.

Thanks to:

269			C<room_lister> then reads that file and queries all services for rooms, and then
270			all rooms for their occupants. The output file is C<room_data.stor>, also a L<Storable>
271			dump, which in turn can be read with C<room_lister_stat>, which transform
272			the data structures into something human readable.
273
274			These scripts are a bit hacky and quite complicated, but maybe it's of any
275			value for someone. You might note L<samples/EVQ.pm> which is a module that
276			handles request-throttling (You don't want to flood the server and risk
277			getting the admins attention :).

280
281			This is a (basic) skeleton for a jabber component.
282
283	elmex	1.26	=item B<samples/simple_oob_retriever>
284
285			This is a simple out of band file transfer receiver bot. It uses C<curl> to
286			fetch the files and also has the sample functionality of sending a file url for
287			someone who sends the bot a 'send <filename>' message.
288
289	elmex	1.27	=item B<samples/simple_register_example>
290
291			This is a example script which allows you to register, unregister and change
292			your password for accounts. Execute it without arguments for more details.

307			=head1 BUGS
308
309	elmex	1.12	Please note that I'm currently (July 2007) the only developer on this project
310			and I'm very busy with my studies in Computer Science in Summer 2007. If you
311	elmex	1.18	want to ease my workload or want timely releases, please send me patches instead
312			of bug reports or feature requests. I won't forget the reports or requests if
313	elmex	1.25	you can't or didn't send patches, but I can't gurantee immediate response.
314			But I will of course try to fix/implement them as soon as possible!
315	elmex	1.12
316	elmex	1.18	Also try to be as precise as possible with bug reports, if you can't send a
317			patch, it would be best if you find out which code doesn't work and tell me
318			why.
319	elmex	1.12
320	elmex	1.1	Please report any bugs or feature requests to
321			C<bug-net-xmpp2 at rt.cpan.org>, or through the web interface at
322			L<http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Net-XMPP2>.
323	elmex	1.18	I will be notified and then you'll automatically be notified of progress on
324	elmex	1.1	your bug as I make changes.

367
368	elmex	1.18	Thanks to the XSF for the development of an open instant messaging protocol (even though it uses "XML").
369	elmex	1.13
370			And thanks to all people who had to listen to my desperate curses about the
371	elmex	1.18	brokenness/braindeadness of XMPP. Without you I would've never brought this
372	elmex	1.13	module to a usable state.

374	elmex	1.17	Thanks to:
