With the search being partially broken ATM, it's a bit annoying to open another community (https://lemmy.world/c/selfhosted) in kbin (https://kbin.social/m/[email protected])
There's an extension for firefox that transforms links found in comments, but it doesn't work if you've already got the community open in its original site.
I've just put together a quick and dirty js bookmarklet for this (mostly for myself, but I figured I'd post it in case anyone else finds it useful).
You basically save this code as a bookmark, and just click it when you're in a community on another site to be taken to that communiy on kbin:
javascript:(function()%7Blet%20reg%20%3D%20window.location.href.match(%2Fhttps%3F%3A%5C%2F%5C%2F(.*)%5C%2F%5Bcm%5D%5C%2F(%5Ba-zA-Z%5D%2B)%5C%2F%3F.*%2F)%3B%0Awindow.location.href%20%3D%20%60https%3A%2F%2Fkbin.social%2Fm%2F%24%7Breg%5B2%5D%7D%40%24%7Breg%5B1%5D%7D%60%3B%7D)()%3B
The original, unminified code is just
let reg = window.location.href.match(/https?:\/\/(.*)\/[cm]\/([a-zA-Z]+)\/?.*/);
window.location.href = `https://kbin.social/m/${reg[2]}@${reg[1]}`;
Unfortunately it doesn't work for threads (seems like they're a bit more complex than a quick find and replace), you need to be on the frontpage of the community
Honestly I'm not sure. I think normally they should only appear if somebody from your instance is subscribed to them or if you search for it manually. Tbh kbin's search has been broken for me since I've joined, so that might have something to do with why nothing shows up?
Although I've checked it now and https://kbin.social/m/[email protected] works and you can subscribe (just doesn't show the post from the original ...yet?) so... maybe there's something more to it.
Hmm, might be a good workaround but dunno why is it now opening the page - I kept getting 404 errors on it before, I'm 100% certain. I subscribed now too so I'll see if it starts getting populated over time.
