AnyEven...MPP::Ext(3)

🌸 AnyEvent::XMPP::Ext(3) — the extension baseclass, bestie edition 🌸

Okay so this is the manual page for AnyEvent::XMPP::Ext(3) (yeah the header up top got cut off, we don't talk about it 💀) — it's part of the User Contributed Perl Documentation, and it's literally both the baseclass and the lore doc for all the extensions. Let's get into it 💅

✨ NAME ✨

AnyEvent::XMPP::Ext — the Extension baseclass and the documentation, both at once, main character energy 👑

🦋 DESCRIPTION 🦋

So this module is doing double duty, no cap:

• it's got the documentation about which extensions are supported, and
• it's the base class for every extension you can bolt on via the add_extension method — the one that lives on all the classes deriving from AnyEvent::XMPP::Extendable.

And which classes are those, you ask? 🫶

• AnyEvent::XMPP::Client
• AnyEvent::XMPP::Connection
• AnyEvent::XMPP::IM::Connection

That's the whole squad, periodt.

🎀 Methods 🎀

💫 disco_feature

You can overwrite this method in your extension, and it should return a list of namespace URIs of the features your extension enables. That's it, that's the method. Slay ✨

🌈 Supportet extensions 🌈

(Yes, that's the heading spelled exactly like that — we keep it iconic, we don't fix it 🫶)

Here's the list of supported XMPP extensions, and bestie there are a lot of them:

• XEP-0004 - Data Forms (Version 2.8) — handles data forms as described in XEP-0004. AnyEvent::XMPP::Ext::DataForm lets you construct, receive and answer data forms. This is neccessary (their spelling, not mine 💖) 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) — lets you send service discovery requests and define a set of discoverable information. See also AnyEvent::XMPP::Ext::Disco.
• XEP-0054 - vcard-temp (Version 1.1) — retrieval and storage of XMPP vcards as defined in XEP-0054. Implemented by AnyEvent::XMPP::Ext::VCard.
• XEP-0066 - Out of Band Data (Version 1.5) — receive and send out of band data URLs, plus helper functions for handling jabber:x:oob data. See also AnyEvent::XMPP::Ext::OOB.
• XEP-0077 - In-Band Registration (Version 2.2) — lets you register new accounts "in-band". For details please take a look at AnyEvent::XMPP::Ext::Registration.
• XEP-0078 - Non-SASL Authentication (Version 2.3) — okay so after lots of sweat and curses iq auth finally got implemented 😭. Unfortunately the XEP-0078 specifies things that are not implemented — in fact, the only server that worked was openfire and psyced.org.

So the iq auth got de-analyzed, and now it just barfs the IQ set out on the stream with the username and the password. Fr fr.

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 AnyEvent::XMPP::Connection.

• XEP-0082 - XMPP Date and Time Profiles (Version 1.0) — implements some functions to deal with XMPP timestamps, see AnyEvent::XMPP::Util to_xmpp_time, to_xmpp_datetime, from_xmpp_datetime.

They're meant as simple formatters for you — you'll 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 enables sending of the old error codes when generating a stanza error — with, for example, the write_error_tag method of AnyEvent::XMPP::Writer.

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 software version, name and operating system requests, and to send such requests, is implemented in AnyEvent::XMPP::Ext::Version.
• XEP-0114 - Jabber Component Protocol (Version 1.5) — lets you 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 samples/simple_component.
• XEP-0153 - vCard-Based Avatars (Version 1.0) — store and retrive (yep, still their spelling 💀) avatars from vcards. On top of that it'll 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) — send ping requests to other entities and reply to them too. On top of that, the AnyEvent::XMPP::Ext::Ping extension implements a connection timeout mechanism based on this. Obsessed 🔥
• 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 an 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. ⭐
