Figured I'd cobble together a quick-n-dirty greasemonkey/tapermonkey script to slighly modify the CSS to feel a little more like old.reddit with RES. Still not quite as compact as I'd like, but it's getting there.

**edit/update: **

changelog

  • All future versions on github: https://github.com/soundjester/lemmy_monkey/
  • v0.4 - reformatted to remove greater-than signs; added observer to catch and reformat new comments;
  • v0.3 - added script to move the comment collapse button to be in front of user name (thanks @DarkwingDuck); tightened up the code, removed unneeded function call.
  • v0.2 - modified to work on any lemmy instance (thank you, God!)
// ==UserScript==
// @name         Lemmy to Old.Reddit Re-format (Observer)

			document.head.appendChild(style);
			return style;
		})();
		const sheet = style.sheet;
		sheet.insertRule(css, (sheet.rules || sheet.cssRules || []).length);
	}

	function MoveCommentCollapseButton(container) {
		var firstTargDiv = container.querySelector(".btn.btn-sm.text-muted");
		var secondTargDiv = container.querySelector(".mr-2");

just so you know, you can make it universal by adding something very simple to your script:

just wrap the script with this:

var isLemmy =
  document.head.querySelector("[name~=Description][content]").content ===
  "Lemmy";

if (isLemmy) {
  // your code here
}

that way ppl don't have to modify their script and it just works by default :)

Instead of querying the description (which I'm not sure is hardcoded or not), a better way to do this would probably be just if (window.lemmyConfig). To me it seems pretty unused and might be gone in later versions, but it exists now and we can take advantage of it.

There is also window.isoData which is probably bit more reliable, but no idea if that naming is Lemmy's or from a framework Lemmy happens to use. Unlike lemmyConfig though it has plenty of data inside which might make it a lot more reliable if you dig deep enough.

What I use I've tested all throughout many instances and it hasn't failed once yet. I didn't understand the first thing but yeah I might go with your suggestion Anyway at least to try it because it seems a tiny bit better practice.

I wanna put this here later, if you get around to doing it before I stop being busy, lmk

This took way too long.

var div_list = document.querySelectorAll(".d-flex.flex-wrap.align-items-center.text-muted.small");
var div_array = [...div_list];
div_array.forEach(container => {
    var firstTargDiv = container.querySelector(".btn.btn-sm.text-muted");
    var secondTargDiv = container.querySelector(".mr-2");

    //-- Swap last to first.
    container.insertBefore (firstTargDiv, secondTargDiv);
});

Edited because I screwed up and only moved the first comment's collapse button. Whoopsie.

@mershed_perderders care to add this?

[–] [email protected] 3 points 1 year ago

This is amazing! Nice work

[–] [email protected] 3 points 1 year ago

an elegant solution. I gave up on it after an hour.

But I didn't mention you lol. Or are you talking about another mention?

[–] [email protected] 2 points 1 year ago (1 children)

I'm sorry, it's late and I'm a bit tired. Indeed you did not mention me, the reason I got notified is because your comment is a response to mine.

[–] [email protected] 3 points 1 year ago (2 children)

@[email protected] @[email protected] I got it. Code changed. Will await the other code, but I'm going to bed now (such a weakling, I know).

[–] [email protected] 2 points 1 year ago (1 children)

@[email protected] @[email protected] what do you guys think would be a good name for a community hosting this kind of augmentations? I was thinking of making something like /c/userscripts or /c/plugins. The latter sounds pretty cool.

[–] [email protected] 1 points 1 year ago (1 children)

I lost this in the comment chain. I think this is a good idea. I think plugins would be good - the next item I want to tackle is an infinite scroll script... pagination is for the birds.

Feel free to share anything there, I will share a couple of things myself. Once you post or comment I'll mod you.

I ran across a script the other day that essentially functioned as an auto-subscribe. The use case was subscribing to a federated community just by visiting and it was super useful. I had it installed, then uninstalled it and now I can't find it (sadface).

[–] [email protected] 1 points 1 year ago

I was thinking of making it hahah. I actually made the basis for it but then had some trouble because of CORS. Was thinking of implementing an iframe to run the API fetch from within but that's so much trouble that I ended up giving up for now. If you find it please let me know.

[–] [email protected] 1 points 1 year ago

Nooo how can you go to bed now! :c (am literally in bed lights off about to sleep) lol

Hello, I made [email protected], when you join and post a comment or make a post, I will mod you.

[–] [email protected] 2 points 1 year ago (1 children)

Also, this is super awesome. I will test it as soon as I'm on desktop tomorrow.

[–] [email protected] 3 points 1 year ago* (last edited 1 year ago) (2 children)

The only issue is this only works on page load, so comments loaded dynamically while you're on the page already won't get the collapse button moved.

[–] [email protected] 3 points 1 year ago

Ahh. I made something for this. It uses some observer. Well, chatgpt made it. I'll find it and send it to you in a sec.

[–] [email protected] 2 points 1 year ago* (last edited 1 year ago)

Here you go. Check the last lines about the observer. I don't know how that works. Honestly I didn't even read it. Chatgpt did that whole part for me. https://sh.itjust.works/post/42893

It doesn't work 100% but it works way better than without it.

[–] [email protected] 1 points 1 year ago

Thank you too :) I bless you for your awesome share.
