[bug#53818] [PATCH 0/3] Add Repology updater

[Xinglu Chen]

Hi,

This patchset adds a new updater, which scans Repology[1] for updates.
It should technically support all packages in Guix!  :-)

The data on Repology isn’t as detailed as the one on language-specific
repos, e.g., PyPI, so the updater doesn’t support things like ‘input
changes’.  If the source URL doesn’t contain the version verbatim[2], it
won’t be able reconstruct the URL of the updated version, meaning that
‘guix refresh -u’ won’t work.

Because of the way ‘%updaters’ in (guix upstream) works, the Repology
updater is the first or second updater that is used (since it
technically works on ever package), but because of the limitations I
mentioned above, the result might not always be the best.  The Repology
updater is mostly useful for things that don’t already have an updater,
e.g., ‘maven-dependency-tree’.  Would it make sense to hard-code the
‘%updaters’ variable and put the Repology last in the list?

[1]: <https://repology.org>
[2]: e.g., the version is “1.0.0” but the URL is
     “https://example.org/1_0_0.tar.gz”
