GitHub comment thread bookmarklets

Useful GitHub bookmarklets

To use: create a new bookmark and paste into the URL field.

In Chrome, you can paste the full multiline code as shown below.
In other browsers, you may need to minify the code into one line first.

1 Expand All Comments.js

javascript:(function() { document.querySelectorAll(".outdated-comment").forEach(function (node) {
  node.classList.add("open");
}) }());

2 Expand All My Comments.js

// In the usual, simple case:
javascript:(function(){ document.querySelectorAll(".js-comment .author").forEach(function (node) {
  if(node.textContent === "<YOUR USERNAME HERE>") {
    for (var parent = node.parentNode; parent; parent = parent.parentNode) {
      if (parent.classList && parent.classList.contains("outdated-comment")) { parent.classList.add("open"); break; }
    }
  }
}) }());

// Or in my case I have two different usernames for GitHub vs. internal GH:
javascript:(function(){ document.querySelectorAll(".js-comment .author").forEach(function (node) {
  if(node.textContent === "pflynn" || node.textContent === "peterflynn") {
    for (var parent = node.parentNode; parent; parent = parent.parentNode) {
      if (parent.classList && parent.classList.contains("outdated-comment")) { parent.classList.add("open"); break; }
    }
  }
}) }());

3 Highlight & Expand All Comments Updated since... .js

javascript:(function(){
  var start=new Date(prompt("Enter Date/Time", new Date()));
  document.querySelectorAll(".js-comment relative-time").forEach(function (node) {
    function closest(node, className) {
      for (var parent = node.parentNode; parent; parent = parent.parentNode) {
        if (parent.classList && parent.classList.contains(className)) return parent;
      }
    }
    var border=closest(node, "js-comment");
    if (new Date(node.getAttribute("datetime")) >= start) {
      border.style.border = "1px solid red";
      var container = closest(border, "outdated-comment");
      if (container) { container.classList.add("open"); }
    } else {
      border.style.border = "";
    }
  });
}());

4 Go to Blame in Parent Commit.js

javascript:(function(){
function closest(node, className) {
  for (var parent = node.parentNode; parent; parent = parent.parentNode) {
    if (parent.classList && parent.classList.contains(className)) return parent;
  }
}

var selectionNode = document.getSelection().anchorNode;
if (!selectionNode) {
    alert("Select text in the file to go to parent blame for that file");
    return;
}
var fileBlock = closest(selectionNode, "file");
var fileRelPath = fileBlock.getElementsByClassName("file-header")[0].dataset.path;
var parentSHABlock = document.querySelectorAll(".commit-meta .sha-block")[0];
var parentSHANodes = parentSHABlock.querySelectorAll(".sha");
if (parentSHANodes.length > 1) {
    alert("Commit has two parents - unsure which to use");
    return;
}
var commitURL = parentSHANodes[0].href;
var url = commitURL.replace("/commit/", "/blame/") + "/" + fileRelPath;

/* Get line number */
var codeCell = closest(selectionNode, "blob-code");
var lineNumCell = codeCell.previousElementSibling;
var lineNum = lineNumCell.dataset.lineNumber;
url += "#L" + lineNum;

/* Navigate to new page */
window.location.href = url;
}());

To get to the logged in user name, this works, though not sure how stable it is: document.querySelector(".user-profile-link").href.replace(/.*\//, "")

The snippets from Expand All My Comments.js don't work for me. I actually don't see any elements with a class name "outdated-comment", so perhaps the interface has changed, so I cooked up an alternative and got this working: https://gist.github.com/haridsv/6b902e3d1a5eb4f4496ef517d56b1f93

@cbowns 's answer works as of 27 aug 2020, but you need to wrap it in a javascript block like this:

javascript:(function() { document.querySelectorAll(".js-resolvable-timeline-thread-container").forEach(function (node) {
  node.open = true;
}) }());

THANK YOU @peterflynn and @cbowns and @yngvark. ⬆️ this is it. See @yngvark's comment just above.

I added that to my gist here: https://gist.github.com/ElectricRCAircraftGuy/0a788876da1386ca0daecbe78b4feb44
