Userscripts

Had my first foray into the wonderful world of userscripts today.

After pushing the Show More button on a Github pull request one too many times, knowing about userscripts, I decided to install TamperMonkey and get to work.

Here’s the script I wrote to click the Show More button until all comments were visible and could be properly audited:

// ==UserScript==
// @name         PR ExpandR
// @namespace    http://ryanfleck.ca/
// @version      1.0
// @description  Expand all GitHub PR conversations.
// @author       Ryan Fleck
// @match        https://github.com/*/pull/*
// ==/UserScript==

var interval = 3000;

function expand_convos() {
  var buttons = document.getElementsByTagName('button');
  for (let i = 0; i < buttons.length; i++) {
    if (buttons[i].textContent.trim().includes('hidden')) {
      window.setTimeout(function () {
        console.log('Clicking button to expand: [ ' + buttons[i].textContent.trim() + ' ].');
        buttons[i].click();
      }, 400);
    }
  }
  window.setTimeout(expand_convos, interval);
}

(function () {
  'use strict';
  console.log('PR Detected, searching for hidden items every ' + interval / 1000 + ' seconds.');
  expand_convos();
})();

To date, this script has saved me a lot of time, and I have written a few others in the meantime, mostly for use on Github.
