Straight.el: Add way to prune unused repositories

[raxod502]

Over time, you can accrue a large number of unused Git repositories that were cloned at various points but are no longer used. I don't want to prune these (they might contain useful development history), but some people who don't modify their Emacs packages might.

This should be customizable. I don't want re-clone some big repos what was removed silently. Indeed automatic clearing is good thing when it's customizable.

[raxod502]

Certainly. I don't want this to be automatic under any circumstances. It would be an interactive function you could call, which would make sure to ask you individually for each repository.

Does this mean there are actually people other than me using this package manager?? :o

Not yet. But I observe this project development and maybe try to use it later.

[raxod502]

Excellent. I really hope I can make a 1.0 release sometime this summer, although I can't guarantee it.

So far, so good! I just started to use it. Keep up with the good work!

Is there any progress on this? Sometimes an ample disk space is not available. I want to be able to automatically remove unused repos that I didn't modify, and manually remove the unused repos that I modified.

Definitely the future of package manager, BTW. I'm aboard.

I don't have time to implement this fully right now, sorry. However, it is easy to hack together something that does the job; try this:

I've been using striaght-x-clean-unused-repos successfully for some time now. Is there anything you feel is lacking design wise or any corner case we haven't considered here?
Seems like a simple enough command to move into straight.el proper.

[raxod502]

Heh, yeah, that seems totally reasonable. Just rename the function (maybe adding a backwards compatibility alias in straight-x.el since it's been there for a few years), and add a docstring, I think!
