Keeping paru cache clean -- Best practices?

[hariganti]

After doing a bit of reading, including the man pages, I'm still a bit confused about a couple of things.

Firstly, here's what I'm trying to do:

1. Avoid keeping more than one old version of a package cached on my system
2. Avoid keeping any removed packages on my system
3. Avoid duplicate source files on my system

From what I read from issues #850 and #925, here is what I think I can do:

• Uncomment CleanAfter from paru.conf to run git clean on the clone directory
• Set PKGDEST in makepkg.conf to the pacman cache (/var/cache/pacman/pkg/)
• Use paccache to manage the cached packages

What I'm not quite clear on is:

• Does paru create a new directory for each new version of an AUR package, or just pull changes from upstream? Essentially, is only the latest version cached by default, or are all versions?
• Does CleanAfter attempt to run pacman -Sc as well or clean the pacman cache?
• Is CleanAfter sufficient to retain only the latest source files?

Thank you!
