Please excuse my sub-par JavaScript, I am a backend dev.
All you need to do is paste this into Tampermonkey and enter your username and your instance url (on two locations).
This is not showing other users' scores and it doesn't make your score visible to anyone else than yourself.
So no need for karma farming. This is just for fun.
// ==UserScript== // @name Lemmy score // @namespace http://tampermonkey.net/ // @version 0.1 // @description Shows your total post/comment score at the top right. // @author You // @match ENTER INSTANCE URL HERE (leave the asterisk after the URL)* // @icon https://www.google.com/s2/favicons?sz=64&domain=feddit.de // @grant none // @run-at document-idle // ==/UserScript== (function() { 'use strict'; var USERNAME = "ENTER USERNAME HERE"; var INSTANCE_URL = "ENTER INSTANCE URL HERE"; var totalScore = 0; var currentPage = 1; function postResult() { var navbar = document.getElementsByClassName("collapse navbar-collapse")[0]; console.log(navbar); var ul = document.createElement("ul"); ul.className = "navbar-nav"; ul.id = "karma-ul"; var li = document.createElement("li"); li.id = "karma-li"; li.className = "nav-item"; li.innerHTML = '<div id="karma-div">' + totalScore + '</div>' navbar.appendChild(ul); ul.appendChild(li); } function callPage() { var userRequest = new XMLHttpRequest(); userRequest.onreadystatechange = function () { if (this.readyState == 4) { if (this.status == 200 ) { var res = JSON.parse(this.responseText); if (res.posts.length==0 && res.comments.length==0) { postResult(); } else { totalScore += res.posts.map(x => x.counts.score).reduce((partialSum, a) => partialSum + a, 0); totalScore += res.comments.map(x => x.counts.score).reduce((partialSum, a) => partialSum + a, 0); currentPage++; callPage(); } } } } userRequest.open("GET", INSTANCE_URL + "/api/v3/user?username=" + USERNAME + "&limit=50&page=" + currentPage, true); userRequest.send(); } setTimeout(callPage, 200); })();
the this.readyState if statement and the this.status could be one statement. e.g. this.readyState === 4 && this.status === 200
also note the three equals instead of two. it's is more performant as it is type specific
Wasn't really looking for a code review. This was just a quick and dirty hack. I didn't even intend to post it here, but someone where I posted it first insisted.
There are a lot of potential optimisations, but the time budget that I wanted to sink into this script was a maximum of 15 minutes.
thanks for sharing :)
