[aura] -Cv: Cache clear vcs contents

[leshow]

closes: #692

I can submit changes for the Rust version in another PR. I re-used the "Cleaning package cache..." translations, if we want that to be more specific we'll need a new set of translations.

I haven't tested it out yet, although the code is pretty straight forward, what's a good way to test? Do you just stack build then execute the binary?

[fosskers]

Personally I often stack install and then just run aura as-is from the command line for both testing and regular use.

[leshow]

Okay, I've built and tried it. Successfully cleared out my vcs dir. I haven't gotten a chance to write Haskell in a while, this was fun. Let me know if it looks good on your end.

edit: while I've got you here, some tools like yay have the ability to tell you which of your set of AUR packages no longer has a corresponding entry in aur.archlinux.org. I think something like like could be useful for aura. What do you think? yay can also list missing/orphaned packages. It lists them every time you run a command which I don't really like but it may be nice to have a subcommand for aura that lists these sorts of things.

[fosskers]

Thanks! I'll get this merged tomorrow (Sunday).

Aura does have -O for operations involving orphans. Is what -Oj does differ from yay's behaviour?

[leshow]

Interestingly the output is different than what aura produces, it also delineates between "missing" and "orphaned". I've used aura for years and know about -Oj but the results are different:

~
❯ sudo aura -Oj

I can make a separate issue for this if you want, I'd like to know exactly what each considers an "orphan"

[fosskers]

Sure, please do.

[leshow]

This PR is good to go? Or did you want me to make the changes to the Rust code here also.

[fosskers]

Forgive me, this should be good to go. I will test and merge it on Friday.

[fosskers]

The changes themselves look good, testing now.

[fosskers]

Works great, thank you. Making a release.

[fosskers]

Released, enjoy.
