XMPP URI scheme links not working

[foss-]

Many projects offer help via XMPP rooms or use XMPP for community building and have users mingle, but GitHub markdown does not seem to support XMPP URI format making it very complicated for users to jump on the XMPP train. That is odd as there were previous issues about this which have been closed:

Markdown parsing of URI schemes #202 (May 2013)
Markdown links don't seem to work if scheme is something "weird" #426 (Dec 2014)
XMPP URI support (RFC5122) #1255 (Feb 2019)

with the last one being the most relevant as it directly references XMPP URI support. I tried this, but even in 2021 GitHub markdown turns XMPP URI links into mailto: links which is a serious problem.

  * [XMPP](xmpp:[email protected])
  * xmpp:[email protected]

Shows as:

• XMPP
• xmpp:[email protected]

What is missing to make this work?

For the record xmpp: is one of the registered and permitted protocol schemes by web browsers. See: https://developer.mozilla.org/en-US/docs/Web/API/Navigator/registerProtocolHandler#permitted_schemes

Dear @github team,

In first, I wish you a Happy New Year 2022!

Have you progressed on it?

Example: xmpp:[email protected] does not work, it is mailto.

It is a standard:

• RFC5122: https://datatracker.ietf.org/doc/html/rfc5122

Based on the examples given in the original comment, this has been fixed! 🎉

@justsostephen: Thanks, xmpp:[email protected] works! :)

But it does not work, it is in https://datatracker.ietf.org/doc/html/rfc5122

• xmpp:[email protected]?message
• xmpp:[email protected]?message;subject=Hello%20World

In https://datatracker.ietf.org/doc/html/rfc5122#section-2.5, there is a note about XEP-0045 (not only):

• xmpp:[email protected]?join (example from https://xmpp.org/extensions/xep-0045.html)
• xmpp:[email protected]?join;password=cauldronburn (example from https://xmpp.org/extensions/xep-0045.html)

Can you look to add more?

It doesn't work for me either.
Take a look at README at https://github.com/psi-im/qca
There is a link to XMPP chat. But it's rendered as plain text.

Please reopen the issue.

@Ri0n rename the README to README.md and it should work. This is a bad habit of linuxoids to not use extensions ;)

Meanwhile there is one issue remains with the xmpp uri inside <a href="xmpp:[email protected]"> links:

• Email: this mailto link works
• XMPP (Jabber): this xmpp link is wrongly use mailto:

Wow, the comment's markdown works fine with the xmpp: anchors but in a repo it doesn't. Check in the bottom of my profile's readme https://github.com/stokito/stokito?tab=readme-ov-file for the [email protected]
