Ingest HGKeeper

Summary:

A lister is needed for HGKeeper, a web frontend for Mercurial/hg repositories.

HGKeeper sites have HGKeeper as the default page title, but it can be customised by the theme config so not every site will use that.

HGKeeper sites can be listed by downloading and parsing the front page, then downloading/parsing group pages, then downloading/parsing repo pages, for example using this shell snippet:

for site ; do
	for group in $(
		curl -sL $site | pup 'h4.mr-auto a attr{href}' | sed "s=^/=$site="
	) ; do
		for repo in $(
			curl -sL $group | pup 'h4.mr-auto a attr{href}' | sed "s=^/=$site="
		) ; do
			curl -sL $repo | pup 'input.hgk-repository-clone-url attr{value}' | sed 's/hg clone //'
		done
	done
done

The front page has the group URLs in the h4.mr-auto a href attribute. The group pages have the repo page URLs in the h4.mr-auto a href attribute. The repo pages have the hg repository URLs in the input.hgk-repository-clone-url value attribute, prefixed with the hg clone command.

According to Google and Bing, there is only one site using HGKeeper:

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
