Remove makedepends after failed and successful build automatically.

pacaur -v

pacaur 4.8.6

Description

It would be nice if there was an option to automatically remove the makedepends (if installed while building) after a failed and successful build.

bump? @E5ten

This is basically what's keeping us from migrating from pakku

[E5ten]

I'll try to give supporting this a shot when I get a chance, in the meantime, thoughts on how this should work? (like should it be default, what option should be made to enable it if not default or disable it if default, etc.)

[tadly]

I honestly think it should be default and while I don't think there's need for it to be configurable, I generally like having the option to turn things on/off.

So, the config file (/etc/xdg/pacaur/config) could be extended with a removemakedepends=true.

I just installed pacaur using pakku and here's a snippet on how it behaves (just in case it isn't clear)

As you can see I still had to confirm the removal as it's just funneled into pacman.
As long as you can keep track of what the makedepends are, this should be pretty trivial.

Hope this helps, thanks for working on it and a happy new year :)

A starting point for this could be the --rmdeps option of makepkg (i think this only works for successful builds). ;)
