XEP-0442 is actually MAM to retrieve pubsub items, not the same as MAM for <message/>.

anyone aware of an alternative to JC's inverse MUC badges (for e.g., github READMEs)? Smack uses https://inverse.chat/badge.svg?room=smack@conference.igniterealtime.org but that appears to be broken since a while

I think we had discussed possibly having search.jabber.network provide badges at some point

I can't see that it's implemented though

flow, Prosody has mod_muc_badge.

I didn't suggest that as I suspect conference.igniterealtime.org isn't running Prosody (but you never know!)

Ah right.

the placement of the participant counter, 7 in this case, seems a bit off

but better than nothing :)

Floating average as the s.j.n also uses?

Ah, the placement, not the counter itself. *facepalm*

I quite dislike the text@textLength render, at least in Firefox.

It seems to assume a specific character width which is quite wrong with most text.

When I remove this attribute, the spacing between characters becomes much nicer.

But of course, aside from JavaScript (and even then?) there is no way to adapt the background width to the rendered text width.

Multiply by something that ought to give some margins, then cry when people stuff in a 300 code point emoji sequence that turns into a single glyph

The one solution I could see, would be to run something like harfbuzz on the server, get the extents, and then generate the SVG hoping the client will use the same font as you did.
