Reverse lookup: deliver snapshots for package version

[andreasabel]

staversion gives me for a resolver the version of a package. However, I'd like to know the resolver, given a versioned package. E.g.

$ staversion Agda-2.6.3
nightly-2023-03-10
$ staversion Agda-2.6.2.2
lts-20.13

I think staversion doesn't serve this direction yet, so this is a feature request.
Or is there a tool yet that does this?

[debug-ito]

staversion doesn't support that feature yet. I'm not sure if there is any tool for that.

I'm sorry but I have no time or motivation to work on staversion for any more development. If you are serious in implementing this feature, I can set you as a co-author.
