AnyEvent::XMPP::Ext - Extension baseclass and documentation
This module also has documentation about the supported extensions and also is a
base class for all extensions that can be added via the
"add_extension" method of the classes that derive from
AnyEvent::XMPP::Extendable. (That are: AnyEvent::XMPP::Client,
AnyEvent::XMPP::Connection and AnyEvent::XMPP::IM::Connection)
- This method can be overwritten by the extension and should
return a list of namespace URIs of the features that the extension
This is the list of supported XMPP extensions:
- XEP-0004 - Data Forms (Version 2.8)
- This extension handles data forms as described in XEP-0004.
AnyEvent::XMPP::Ext::DataForm allows you to construct, receive and answer
data forms. This is neccessary for all sorts of things in XMPP. For
example XEP-0055 (Jabber Search) or also In-band registration.
- XEP-0030 - Service Discovery (Version 2.3)
- This extension allows you to send service discovery
requests and define a set of discoverable information. See also
- XEP-0054 - vcard-temp (Version 1.1)
- This extension allows the retrieval and storage of XMPP
vcards as defined in XEP-0054. It is implemented by
- XEP-0066 - Out of Band Data (Version 1.5)
- This extension allows to receive and send out of band data
URLs and provides helper functions to handle jabber:x:oob data. See also
- XEP-0077 - In-Band Registration (Version 2.2)
- This extension lets you register new accounts
"in-band". For details please take a look at
- XEP-0078 - Non-SASL Authentication (Version 2.3)
- After lots of sweat and curses I implemented finally iq
auth. Unfortunately the XEP-0078 specifies things that are not
implemented, in fact the only server that worked was openfire and
So I de-analyzed the iq auth and now it just barfs the IQ set out on the
stream with the username and the password.
If you insist on XEP-0078 behaviour enable the "anal_iq_auth"
option when creating the stream.
You can also completely disable iq auth, well, just see the documentation of
- XEP-0082 - XMPP Date and Time Profiles (Version 1.0)
- Implemented some functions to deal with XMPP timestamps,
see AnyEvent::XMPP::Util "to_xmpp_time",
They are meant as simple formatters for you, you will still need to handle
timezone stuff and such yourself.
- XEP-0086 - Error Condition Mappings (Version 1.0)
"A mapping to enable legacy entities to correctly handle errors from XMPP-aware entities."
This extension will enable sending of the old error codes when generating a
stanza error with for example the "write_error_tag" method of
Also if only the old numeric codes are supplied the
AnyEvent::XMPP::Error::Stanza class tries to map the numeric codes to the
new error conditions if possible.
- XEP-0091 - Delayed Delivery (Version 1.3)
- See also XEP-0203 below.
- XEP-0092 - Software Version (Version 1.1)
- The ability to answer to software version, name and
operating system requests and being able to send such requests is
implemented in AnyEvent::XMPP::Ext::Version.
- XEP-0114 - Jabber Component Protocol (Version 1.5)
- This extension allows you to connect to a server as a
component and makes it possible to implement services like pubsub, muc, or
whatever you can imagine (even gateways). See documentation of
AnyEvent::XMPP::Component and the example
- XEP-0153 - vCard-Based Avatars (Version 1.0)
- This extension allows to store and retrive avatars from
vcards. On top of that it will also signal others that you support avatars
and that they might have changed. See AnyEvent::XMPP::Ext::VCard.
- XEP-0199 - XMPP Ping (Version 1.0)
- You can send ping requests to other entities and also are
able to reply to them. On top of that the AnyEvent::XMPP::Ext::Ping
extension implements a connection timeout mechanism based on this.
- XEP-0203 - Delayed Delivery (Version 1.0)
- Both delayed delivery XEPs are supported and are
implemented by AnyEvent::XMPP::IM::Delayed which is a super class of
AnyEvent::XMPP::IM::Message and AnyEvent::XMPP::IM::Presence.
If you need to fetch delay from stanzas you caught yourself in an event you
can use a AnyEvent::XMPP::IM::Delayed object to parse/fetch the delay out
of the AnyEvent::XMPP::Node.
Use the functions described above in the XEP-0082 item to decode the
timestamps of delays.
