Bookmarklet: Load All GitHub Comments

What happened was, Brian and I were chatting about W3C GitHub issues and Brian mentioned how really long issues are annoying to search and read, because GitHub has this thing where if there are too many comments on an issue, it snips out the middle with a “Load more…” button that’s very tastefully designed and pretty easy to miss if you’re quick-scrolling to try to catch up.  The squiggle-line would be a good marker, if it weren’t so tasteful as to blend into the background in a way that makes the Baby WCAG cry.

And what’s worse, from this perspective, is that if the issue has been discussed to a very particular kind of death, the “Load more…” button can have more “Load more…” buttons hiding within.  So even if you know there was an interesting comment, and you remember a word or two of it, page-searching in your browser will do no good if the comment in question is buried one or more XMLHTTPRequest calls deep.

“I really wish GitHub had an ‘expand all comments’ button at the top or something,” Brian said (or words to that effect).

Well, it was a Friday afternoon and I was feeling code-hacky, so I wrote a bookmarklet.  Here it is in easy-to-save hyperlink form:

It waits half a second after you activate it to find all the buttons on the page (in my test runs, usually six hundred of them).  Then it looks through all the buttons to find the ones that have a textContent of “Load more…” and dispatches a click event to each one.  With that done, it waits five seconds and does it all again, waits five seconds to do it again, and so on.  Once it finds there are zero buttons with the “Load more…” textContent, it exits.  And, if five seconds is too quick due to slow loading times, you can always invoke the bookmarklet again should you come across a “Load more…” button.

If you want this ability for yourself, just drag the link above into your bookmark toolbar or bookmarks menu, and whenever you load up a mega-thread GitHub issue, fire the bookmarklet to load all the comments.  I imagine there may be cleaner ways to do this, but I was able to codeslam this in about 15 minutes using ViolentMonkey on live GitHub pages, and it does the thing.

I did consider complexifying the ViolentMonkey script so that any GitHub page is scanned for the “Load more…” button, and if one is present, then a “Load all comments” button is plopped into the top of the page, but I knew that would take at least another 15 minutes and my codeslam window was closing.  Also, it would require anyone using it to run ViolentMonkey (or equivalent) all the time, whereas the bookmarlet has zero impact unless the user invokes it.  If you want to extend this into something more than it is and share your solution with the world, by all means feel free.

The point of all this being, if you too wish GitHub had an easy way to load all the comments without you having to search for the “Load more…” button yourself, now there’s a bookmarklet made just for you.  Enjoy!
