Fix Endless Scrolling

[SamHasler]

Fixes #23

Tracking testing progress. This is the current state of the patch:

Page Types

• News (Home) — td.title a[href^="news?p="]

• Newest — td.title a[href^="newest?next="]

• Threads

• newcomments

• Upvoted Stories (private)

• Upvoted Comments (private)

• Favorite Submissions

• Favorite Comments

• Show

• Ask

• Jobs

• Show New

• Submitted

• Over

• check for any other page types I've missed

NB: Threads "above the fold" bug is probably present on all pages given the right data/screen-size

Page Types no longer used? Remove code:

• My saved — td.title a[href^="saved"]
  Now called 'Favorite Stories'. See above.
• Threads (x) — td.title a[href^="/x"]

Misc

• is dropping the td.title from the selectors more performant/future-proof?

Wow, thanks! In your testing did it only load one page and then not load further pages?

[SamHasler]

On some pages yes. I'll see if I can fix that next week.

Maybe we should merge this, it's much better than what's in use already

[SamHasler]

I have something that's much better. I'll try and find time to commit it tomorrow. If you don't here from me soon by all means merge.

I've added my current version. It's much better than the live version, however, there are some issues which I've listed below. They're relatively minor apart from the ":warning:" layout one. I'll see if I can fix that but I probably won't be looking at the rest any time soon.

Untested

• Favorite Comments - Haven't found a user with >30 comments to require paging.

Known issues:

• Upvoted Comments (private)
  • ⚠️ 2 column layout issue after page for first more link appended.
  • spinner gifs aren't removed (not after a .morespace row)
• Threads
  • If More is visible above the fold on first page then endless scrolling doesn't trigger. Resizing browser to make page smaller and then scrolling down will trigger it.
• Item / Stories
  • Extra story heading inserted at bottom
• New Comments
  • spinner gifs aren't removed (not after a .morespace row)
• Favourite Submissions
  • extra "submissions | comments" links inserted
• Show
  • extra "Please read the rules. You can also browse the newest Show HNs." inserted
• Jobs
• extra "These are jobs at startups that were funded by Y Combinator. You can also get a job at a YC startup through Triplebyte." inserted

NB: I also tested the links on the lists page and couldn't find anything other the the issues above.

@SamHasler
I haven't tried this extension yet, let alone the PR, but here's a user with lots of favorite comments: https://news.ycombinator.com/favorites?id=danso (#4 author on HN according to this old list https://github.com/antontarasenko/smq/blob/master/reports/hackernews-top-authors-by-h-index.md)

I think HN has blocked me for opening too many comments pages at once, so I hope this info is useful :-/

[SamHasler]

@seanf Thanks for the test page. If the block doesn't lift try emailing hn@ycombinator.com

I'm fairly sure HN changed since I made this PR (I think the selectors are simpler now). I've fixed more pages now so I'll have to update it if I find the time.
