NAME

AnyEvent::XMPP::Client - XMPP Client abstraction

SYNOPSIS

   use AnyEvent::XMPP::Client;
   use AnyEvent;
   my $j = AnyEvent->condvar;
   my $cl = AnyEvent::XMPP::Client->new;
   $cl->start;
   $j->wait;

DESCRIPTION

This module tries to implement a straight forward and easy to use API to communicate with XMPP entities. AnyEvent::XMPP::Client handles connections and timeouts and all such stuff for you.
For more flexibility please have a look at AnyEvent::XMPP::Connection and AnyEvent::XMPP::IM::Connection, they allow you to control what and how something is being sent more precisely.

METHODS

new (%args)

Following arguments can be passed in %args:
debug => 1
This will install callbacks which produce debugging output. This will require XML::Twig to be installed (as it is used for pretty printing the "XML" output).

add_account ($jid, $password, $host, $port, $connection_args)

This method adds a jabber account for connection with the JID $jid and the password $password.
$host and $port can be undef and their default will be the domain of the $jid and the default for the "port" parameter to the constructor of AnyEvent::XMPP::Connection (look there for details about DNS-SRV lookups).
$connection_args must either be undef or a hash reference to additional arguments for the constructor of the AnyEvent::XMPP::IM::Connection that will be used to connect the account.
Returns 1 on success and undef when the account already exists.

start ()

This method initiates the connections to the XMPP servers.

update_connections ()

This method tries to connect all unconnected accounts.

disconnect ($msg)

Disconnect all accounts.

remove_accounts ($reason)

Removes all accounts and disconnects. $reason should be some descriptive reason why this account was removed (just for logging purposes).

remove_account ($acc, $reason)

Removes and disconnects account $acc (which is a AnyEvent::XMPP::IM::Account object). The reason for the removal can be given via $reason.

set_accounts (%$accounts)

Sets the set of (to be connected) accounts. $accounts must be a hash reference which contains the JIDs of the accounts as keys and the values for $password, $domain, $port and $connection_args as described in "add_account" above.
If the account is not yet connected it will be connected on the next call to "update_connections" and if an account is connected that is not in $accounts it will be disconnected.

send_message ($msg, $dest_jid, $src, $type)

Sends a message to the destination $dest_jid. $msg can either be a string or a AnyEvent::XMPP::IM::Message object. If $msg is such an object $dest_jid is optional, but will, when passed, override the destination of the message.
NOTE: $dest_jid is transformed into a bare JID and the routing is done by the conversation tracking mechanism which keeps track of which resource should get the message.
$src is optional. It specifies which account to use to send the message. If it is not passed AnyEvent::XMPP::Client will try to find an account itself. First it will look through all rosters to find $dest_jid and if none found it will pick any of the accounts that are connected.
$src can either be a JID or a AnyEvent::XMPP::IM::Account object as returned by "add_account" and "get_account".
$type is optional but overrides the type of the message object in $msg if $msg is such an object.
$type should be 'chat' for normal chatter. If no $type is specified the type of the message defaults to the value documented in AnyEvent::XMPP::IM::Message (should be 'normal').

get_account ($jid)

Returns the AnyEvent::XMPP::IM::Account account object for the JID $jid if there is any such account added. (returns undef otherwise).

get_accounts ()

Returns a list of AnyEvent::XMPP::IM::Accounts.

get_connected_accounts ()

Returns a list of connected AnyEvent::XMPP::IM::Accounts.
Same as:
  grep { $_->is_connected } $client->get_accounts ();

find_account_for_dest_jid ($jid)

This method tries to find any account that has the contact $jid on his roster. If no account with $jid on his roster was found it takes the first one that is connected. (Return value is a AnyEvent::XMPP::IM::Account object).
If no account is connected it returns undef.

get_contacts_for_jid ($jid)

This method returns all contacts that we are connected to. That means: It joins the contact lists of all account's rosters that we are connected to.

get_priority_presence_for_jid ($jid)

This method returns the presence for the contact $jid with the highest priority.
If the contact $jid is on multiple account's rosters it's undefined which roster the presence belongs to.

set_presence ($show, $status, $priority)

This sets the presence of all accounts. For a meaning of $show, $status and $priority see the description of the %attrs hash in "send_presence" method of AnyEvent::XMPP::Writer.

EVENTS

In the following event descriptions the argument $account is always a AnyEvent::XMPP::IM::Account object.
All events from AnyEvent::XMPP::IM::Connection are forwarded to the client, only that the first argument for every event is a $account object.
Aside fom those, these events can be registered on with "reg_cb":
connected => $account
This event is sent when the $account was successfully connected.
connect_error => $account, $reason
This event is emitted when an error occured in the connection process for the account $account.
error => $account, $error
This event is emitted when any error occured while communicating over the connection to the $account - after a connection was established.
 
$error is an error object which is derived from AnyEvent::XMPP::Error. It will reveal human readable information about the error by calling the "string ()" method (which returns a descriptive error string about the nature of the error).
added_account => $account
Called whenever an account is added.
removed_account => $account
Called whenever an account is removed.
