Hi, I'm trying to play around with modifying ejabberd with new xmpp commands with more functionality and I was wondering what the "easiest" client would be to use to do that? I've tried using conversejs and strophe directly but are there any other options?

Like say I wanted to display mod_time on a website.

https://github.com/processone/ejabberd/blob/master/src/mod_time.erl

Probably depends mostly on what (languages etc) you're most familiar with already.

hmm, I'm a data scientist by trade. I thought these javascript clients would be easiest since I've done work in that language and haven't done much Gui work

to be honest, I'd just be happy with a client that had some walkthroughs instead of slogging through the mud on my own

like I just wondered what other people do? Are there like XMPP tools I don't know about or utilities to make this easier? Or do people just adjust their servers/clients and then fire up wireshark or something?

It depends. Personally I'm pretty likely to try to solve whatever by writing Prosody modules or whatever in Lua, since that's what I'm most familiar with.

word

As for JS and Strophe.js, I still have this book on a shelf somewhere: http://professionalxmpp.com/

yeah I saw that. Did you think it was good?

I think so. Was some time ago I read it last tho.

word, well I'll order it and see then.

Hm, https://strophe.im/strophejs/#documentation--tutorials looks like a short list

yeah I saw those

but they were a bit opaque :p

at least for my skillset. However, I'll dive back into those for now I guess

I'm just at the don't know what I don't know part of my journey here with XMPP

And it looks like the links have broken :(

some of them, they're still in the github repo

another weird thing about that project is I had to fiddle with the makefile to get it to build

they rely on naturaldocs which is some kind of .Net tool for doing documentation

Wasn't a quick way to get it working on linux

Nothing I've heard about

daidoji, am i understanding you correctly, you want for example to modify the server moudle mod_time

and just need a client to test your modifications?

hello anyone online?

Yep

i have a question about strophe lol

someone is already mentioned it above

im trying to connect to an xmpp server using strophe and i get the xml out put and strophe shows that my user name is password is correct but for some reason its not connecting.

No idea about strophe but maybe someone else knows it.

same thing with xmpp.js

Is there a server that has code for XEP-0436 (MUC presence versioning) yet? I couldn't find anything but perhaps there's branch or module I overlooked

lksjdflksjdf, given that it's co-authored by matthew, I'd look into the prosody trunk

lovetox well I wanted to add some capabilities to a muc room

and I thought hte best way to do that is add some IQ stanzas and some other things

but then I need to modify the client on one side and the server on the other and there aren't really good tutorials or walkthroughs on how to do that

daidoji: Have you gotten enough of strophe.js working to send an iq stanza?

Once connected, it'd be something like: `connection.sendIQ($iq({type:"get",id:connection.getUniqueId()}).c("time",{xmlns:"urn:xmpp:time"}), (r) => console.log(new Date(r.firstChild.getElementsByTagName("utc")[0].textContent)))`

In Prosody, that's responded to by https://hg.prosody.im/trunk/file/tip/plugins/mod_time.lua

lksjdflksjdf: in not aware of any implementation yet

ok thanks for the info

I'm wondering something about the XEP though ... A user goes offline and online again - are we back to the same version? What if the user switches clients, is that still the same version?

Zash yeah I figured that out just last night after I got off

Gajim has a XML Console

where you can simply put in the xml you want, and it sends it for you

also you can see what you get back from the server, if thats what you want

lovetox oh wow that's awesome. Thanks

lksjdflksjdf: it could be the same version if the state of the room is exactly the same

That's all the XEP needs to specify

Same could apply to roster versioning

Yes

I understand that you want to leave the details up to implementations 🤔️ I'm just more interested in the details of muc versioning (implementations) than the details of roster versioning, because there tend to be much more changes there. Like, if I leave a 300-person MUC at night and rejoin it the morning after. If 280 of those 300 people are the same and I only get 20 presences, that'd be nice. But if I still get 300 presences because everyone rejoined or is online with different resources, I'm not too excited about the feature anymore.

lksjdflksjdf, if a person named 'bob' is there right now and tommorow you don't even know if it's the same person or not

lksjdflksjdf: if you rejoin 8 hours later I don't think it's terrible if you have to refetch

moparisthebest, you mean if it _wasn't_ a different version after bob rejoined, I wouldn't know if it's the same person? Technically you could, with occupant ids. But without occupant ids that's true.

While there'll be more stuff going on with presence, it's probably still worth it to look at roster versioning and how that's implemented, since it's basically the same model.

You have stuff, that may change, and you have some token that identifies a specific version of it. You show the server the token and you get something that's supposed to sync your state with the servers.

> if you rejoin 8 hours later I don't think it's terrible if you have to refetch aw 🙁 but it takes time and bandwidth. Sure it's not "terrible" but I was hoping it could be partially eliminated

I'm not saying it can't

But I think that's stretching the goals

With roster versioning, if sending the delta would be larger than just sending the roster ... then just send the roster!

Or if you don't have enough deltas. Or if you don't actually keep deltas at all, in which case it's just a ETag-ish thing.

hi guys it's my first time using xmpp

say something if it's working

Zash, what's an "ETag"?

testhello, "something"

testhello, it's working 😉

woah

lksjdflksjdf, HTTP cache thing.

dude this is like the original QQ or wechat

you mean your client looks like it was from 15 years ago? 😛

One of the nice things is that if you don't like the client, there are others you can use.

I head Tencent originally ripped off of something I guess this is the one huh...

jonas’, was there any progress on the avatar from muclumbus front?
