[mediawiki/core@master] Add UI support in Special:EditWatchlist

https://gerrit.wikimedia.org/r/611439

@Prtksxna @ifried during the code review for this patch, it has been mentioned that perhaps the text to indicate remaining days for temporarily watched items should be @color-base--subtle: @wmui-color-base30;, which is @wmui-color-base30: #72777d;. We have set it to Base 20 Gray - #54595d but I just wanted to run this by you.

@HMonroy Thanks for this update! I'm not totally clear on the context, so can you share why this suggestion has been made?

I noticed it. The reason was that @colorGray5: #54595d (aka Base 20 Gray) is defined along with the comment:

All @colorGray* variables are only for reference. They will be replaced by WikimediaUI Base variables. Use semantic color names such as @color-base below.

But there's no color-base* variable using colorGray5; the closest one defined is color-base--subtle.

In other places (for example, the descriptions in the search results in TemplateWizard) we use the lighter color.

Maybe there's no worry, and no need to change, but I wanted to just make sure.

Where is this from? 🤔

You're right, according to wikimedia-ui-base, --color-base--subtle is #72777d.

Either is fine, since 20 is higher contrast than 30, we could continue using it :)

It's a comment in resources/src/mediawiki.less/mediawiki.ui/variables.less.

• Indicate remaining days for temporarily watched items
  • Display text, directly following the talk/history links in color-base--subtle - #72777d
  • Text should read: "XX days left in your watchlist"

True. Rounds up like action=watch

• If the watch period for a page is less than "1 day left," display the time remaining as "A few hours left"

True.

• Leave behavior unchanged for pages that are being watched permanently

No change to their appearance.

• Display temporarily watched items at top (i.e., they should be separated from permanently watched items)

True.

It should be noted that items are grouped according to namespace (see screenshot for example).

• Sort items according to expiration date, with the items that will expire soonest at the top.

True.

• If multiple items have the exact same expiration time in the system, those items should be sorted alphabetically

True.

Screenshot:

I also tested Special:EditWatchlist with Watchlist Expiry disabled (on my local environment). Seemed fine. No errors in the logs.
