JS Bookmarklet for Switching to 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;if(currUrl[3]=="m"){currUrl[3]="c";}let newUrl=currUrl.join("/");if(!(currUrl[-1].includes("@"))){newUrl=newUrl+"@"+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;
		// fix for kbin using "m" instead, 
		// without overriding /u/ for user
		if (currUrl[3]=="m") {
			currUrl[3]="c";
		}
		let newUrl=currUrl.join("/");
		// fix for already foreign instances (e.g. lemm.ee/c/[email protected])
		if (!currUrl[-1].includes("@")) {
			newUrl=newUrl+"@"+currInst;
		}
		window.location=newUrl;
	})
()

		currUrl[2]=myInst;
		currUrl[3]="c";  // fix for kbin using "m" instead
		let newUrl=currUrl.join("/")+"@"+currInst;
		window.location=newUrl;
	})
