jdev - 2025-06-27

On the phone so I can't do a ton of troubleshooting but I figured I would ask and see if there's a lead. I wrote a bot that processes commands sent to it via chat. I'm using the golang mellium package and there's just really inconsistent behavior. With the tee reader enabled, I can see my messages hitting the server and they don't get processed but I also am not seeing any errors. Like it gets to the server and then just stops. Wondering if anyone has experience with this library and if there's any more advanced implementation than what's available in the examples repo. Been troubleshooting this one for a minute. Any help would be appreciated!

last time i ran into something like that with mellium i was accidentally not doing an if err != nil check

if its helpful the mellium muc is xmpp:users@mellium.chat?join

That is helpful. I'll go through my error checks again and name sure i didn't miss anything

yeah for me, it ended up i was passing it a struct that the encoder didnt understand the shape of

since its specific for xmpp not just going to xml

Were you getting inconsistent messages? Some would deliver and others wouldn't?

it was a particular routine i had, that i couldnt figure out why it wasnt sending

I think we might be having different experiences. I cannot consistently reproduce the error. It is just sometimes I send a command for the bot and it works and others it just fails.

ah idk then

Yeah, I'm hoping it's like some arcane xml decoding issue

fausty: The mellium dev is running this muc: xmpp:go@gopher.chat?join So maybe ask there, too.

Thanks! I'll check it out.

Good afternoon. Is Zulip based upon XMPP? If not, are there plans for Zulip to support XMPP? https://zulip.com

I want to propose to Lichess to utilize XMPP, yet, they seem to be utilizing Zulip. https://github.com/lichess-org/zulip

I don't think Zulip supports XMPP. There was some discussion in the Modern XMPP room recently about creating an XMPP based team chat interface, where we were discussing some ideas from Zulip on how to handle threads ✏

wgreenhouse. Thank you for the information.

Perhaps we should advise to Zulip to add support for XMPP.

> Perhaps we should advise to Zulip to add support for XMPP. Perhaps. I am not aware of any first-party bridge/transport. I think people can currently use bot-style bridges like Matterbridge between the two. ↺

I think that JC intends to do something of sort with Converse. > Slack-like message threads. https://opkode.com/blog/2025-05-21-converse-11/ ✏ ↺

which would of course not do anything useful with Zulip's threading ✏

Zulip isn't aimed at cross-instance so I wouldn't expect it to voluntarily switch it all to XMPP. Federation brings many questions that are not easy to answer

that would also be my guess of the likely response. Zulip and Zephyr are more like rich, persistent internal comms than more ephemeral but federated comms.

then again, IRC is our best bridge story right now so the universe could surprise us

Is Mr. Hal Rottenberg still over XMPP? https://halr9000.com/authors/hal-rottenberg/

> In IQ sets regarding affiliations, a MUC client MUST include the 'jid' attribute only But Tkabber sends both jid and nick. Does it behave out of spec or maybe I just misunderstand it and it means "only jid is mandated"?

yeah weird, it behaves out of spec, but the chance that a MUC server cares is very slim

lovetox: I implemented a check and regretted quite rapidly ×D

What happened to wiki.xmpp.org, BTW?

NVM, it's up again.

Do some clients support mucsub?
