Expand all "outdated diff" comments in a GitHub pull request

When you post a bunch of comments to a pull request, and the author pushes up changes to address the comments, you're often left with a bunch of collapsed comments like this:


If you're like me, sometimes you want to refer back to your earlier comments when reviewing the latest changes – maybe to make sure they're all fixed in the new version, or maybe you just want to search for one important note (Cmd+F ignores collapsed comments!).

Here's a quick bookmarklet to expand all those collapsed comments in one shot:


13 Responses
Add your response

Follow-on: if you want to expand just your own comments, use this:

javascript:(function(){$(".outdated-diff-comment-container").filter(function () { return this.firstElementChild.textContent.indexOf("peterflynn") !== -1; }).addClass("open");}());

(Replacing "peterflynn" with your GitHub user id)

Another useful one... to expand all "outdated" comment threads that actually have a recent comment in them:

javascript:(function(){var start=new Date("19 Oct 2013"); $(".comment-header-date").filter(function () { return new Date(this.firstElementChild.getAttribute("datetime")) >= start; }).closest(".outdated-diff-comment-container").addClass("open");}());

(Replacing the start date as appropriate)

Note: do not use ISO-style dates ("2013-10-19") unless you also specify a time zone -- unlike other date formats that assume your local timezone unless otherwise specified, ISO is apparently assumed to be UTC time by default.

How to make outdated diff comment

over 1 year ago ·

When on GitHub page for a pull request and I run this bookmarklet, it does not expand any of the outdate diffs.

@meellly It still works fine for me. Can you give an example pull request URL on GitHub where it doesn't work?

My apologies it works now. Thank you! Very helpful

Do you know of a way to hide all comments? I've tried replacing ("open") with ("hide") and then with ("close").

Thank you for this article.

Now GitHub seems to no longer use jQuery, so this bookmarklet doesn't work.

error: Uncaught TypeError: $ is not a function

So Please update this article using pure JavaScript like this:

javascript:(function() {var list = document.getElementsByClassName("outdated-diff-comment-container"); for (var i = 0; i < list.length; i++) {list[i].classList.add("open");} ;}());

Just some code golfing:

javascript:Array.from(document.getElementsByClassName('outdated-diff-comment-container')).forEach(l => l.classList.add('open'));

The class name has changed to outdated-comment.

javascript:Array.from(document.getElementsByClassName('outdated-comment')).forEach(l => l.classList.add('open'));

The className has changed again:
This works for me:
javascript:Array.from(document.getElementsByClassName('outdated-diff-comment-container')).forEach(l => l.classList.add('open'));

It seems that old pull requests have the class name 'outdated-diff-comment-container' and pull requests created after specification change have the class name 'outdated-comment'.

This works for both.

javascript: Array.from(document.getElementsByClassName('outdated-diff-comment-container')).concat(Array.from(document.getElementsByClassName('outdated-comment'))).forEach(l => l.classList.add('open'));

Where exactly do you insert this javascript?
