JS Bookmarklet for Switching to lemmy.world (lemmy.world)

i find it annoying to have to manually change urls to subscribe to a community outside lemmy.world, so i wrote a bookmarklet to quickly switch to the lemmy.world instance

to use, just drag the following code to your bookmarks bar (name it whatever you like), then click it when you want to use it

javascript:(function() {const myInst="lemmy.world";let currUrl=window.location.toString().split("/");let currInst=currUrl[2];currUrl[2]=myInst;let newUrl=currUrl.join("/")+"@"+currInst;window.location=newUrl;})();

readable version:

javascript:(
	function() {
		// make sure to change this if using on a different instance
		const myInst="lemmy.world";
		let currUrl=window.location.toString().split("/");
		let currInst=currUrl[2];
		currUrl[2]=myInst;
		let newUrl=currUrl.join("/")+"@"+currInst;
		window.location=newUrl;
	})

Hello, I just made a new bookmarklet where it automatically transfers all of your subscribed communities to another instance, can be found here

[–] Zeus@lemmy.world 2 points 1 year ago* (last edited 1 year ago)

i'll be honest, i'm not sure what that's for? is it moving to another account if you want to change your home instance? if so, that's a good idea, i could add it to the post if you want in case this comment gets buried

spoiler

although i'm not entirely certain using https://github.com/Rob--W/cors-anywhere/issues/301 is a great idea..

[–] Gamera8ID@lemm.ee 1 points 1 year ago

Tried this with a throwaway, but it's broken.

Subscription location has changed.

When corrected, it asks to visit https://cors-anywhere.herokuapp.com/corsdemo to request access. Despite doing so, it never gets past that point.

When/if you fix it, you might give some context about how you're handling user credentials.

Do you know if the process works differently in FireFox? (Note that technically I use Ghostery but it's based in Firefox). I copied the script to a new bookmark URL and changed lemmy.world to lemmy.one since thats the instance I'm registered on. However, when clicked nothing happens. Is there something I'm missing?

[–] Zeus@lemmy.world 2 points 1 year ago (1 children)

i can tell you that i made and currently use it with firefox...

sanity check, when you select edit bookmark it should look like this

however, i don't know about ghostery (i didn't even know they made a browser). it's possible they block arbitrary js for security reasons? it would be a dumb choice in my opinion, but i guess it's protecting you from yourself?

however i can tell you a couple of things. this doesn't work with some communities (they just 404), but that happens if one puts the url in manually. i don't know when or why this happens, but it does seem to happen a lot with lemmy.one. i wonder if it's a l.1 federation issue

[–] Grenfur@lemmy.one 2 points 1 year ago (2 children)

Interesting. ok I'll dig further into it being Ghostery related then.

For your sanity, yes, looks relatively the same on me end when I edit bookmark.

[–] Zeus@lemmy.world 2 points 1 year ago (1 children)

weird. sorry i couldn't help further.. : (

[–] Grenfur@lemmy.one 2 points 1 year ago

No worries at all. I actually found a post working on a FF extension that I think will work. https://beehaw.org/post/493791. Similar idea, but adds an icon to the left of links.

I appreciate you taking the time to look into it though!

[–] Zeus@lemmy.world 1 points 1 year ago

weird - sorry i couldn't help.. : (

[–] Yoru@lemmy.world 2 points 1 year ago (1 children)

also, you should replace const myInst="lemmy.world"; with const myInst = window.location.hostname;, it automatically fetches what instance you're on.

[–] Zeus@lemmy.world 1 points 1 year ago* (last edited 1 year ago)

that (unless i'm misunderstanding) isn't the point of it. it's made for quickly taking you from e.g. https://lemmy.ml/c/jerboa to https://lemmy.world/c/jerboa@lemmy.ml, so it needs a const to know which instance to take you to

edit: i guess i could replace let currInst=currUrl[2]; with let currInst=window.location.hostname; but i can't see a practical difference and so i chose the shorter one

[–] RockDeBilly@lemmy.world 1 points 1 year ago* (last edited 1 year ago)

Thanks that super useful, especially in places like /c/newcommunities where people (including me) are still unsure how to properly link communities.

[–] god@lemmy.world 0 points 1 year ago* (last edited 1 year ago) (1 children)

do you know of any way to switch not a community but a post to another instance? afaik they're numeric so the number identifier is different on each instance which makes it hard.

[–] Zeus@lemmy.world 0 points 1 year ago* (last edited 1 year ago) (2 children)

i'm afraid i don't. i did fiddle around a bit trying to find a relationship between url's, but I couldn't see one

if anyone more familiar with lemmy/activitypub can tell me, I'll update / add to the bookmarklet

[–] LonelyNematocyst@lemmy.world 2 points 1 year ago (1 children)

Staying on your home instance is currently an issue on the repo. Implementing it yourself would need using the search, which is complicated because it only works through a websocket connection.

[–] Zeus@lemmy.world 1 points 1 year ago

i'm glad that's being tracked, as a bookmarklet is not really a great solution; but it's still not a complete solution. if i visit a lemmy post from outside lemmy.world (e.g. search engine), then there's no way to go to the l.w version (to my knowledge)

[–] god@lemmy.world 0 points 1 year ago (1 children)

You probably understood me the first time but I'm editing because I made a mistake in how I phrased it.

to another ~~community~~ → instance

the number identifier is different on each ~~community~~ → instance

[–] Zeus@lemmy.world 1 points 1 year ago

for clarity, i'm presuming you're talking about redirecting from e.g. this [https://lemmy.ml/post/1190997] to this [https://lemmy.world/post/38761]

but yeah, i'm afraid i can't help [yet?]
