whishlist: guix build -d /gnu/store/hash-pkg-version?

[zimoun]

Dear,

When debugging, I find really useful the command: "guix build -d package".

Is it possible to do the same on the resulting '/gnu/store/<path>'?

For example,

$ guix build hello
/gnu/store/kg9mirg6xbvzcp0a98v7326n1nvvwgsj-hello-2.10

$ guix build -d hello
/gnu/store/gknm68l0q893bpvyhcd4ccih1bmh0j87-hello-2.10.drv

Well, I would like to do something like that?

$ guix build -d /gnu/store/kg9mirg6xbvzcp0a98v7326n1nvvwgsj-hello-2.10
/gnu/store/gknm68l0q893bpvyhcd4ccih1bmh0j87-hello-2.10.drv

Does it make sense?


Currently, I am using a combination of "guix gc --list-dead |grep" or
"guix gc --list-live|grep".   But it is not really handy; especially
when there is several times the same package-version (with grafts).

Thank you in advance for any advice.

Best regards,
simon

That does make sense and is already supported with 'guix gc --derivers':

$ guix gc --derivers /gnu/store/a462kby1q51ndvxdv3b6p0rsixxrgx1h-hello-2.10
/gnu/store/8s63hyw4f2ivf1zxkx65awlx5jackvbz-hello-2.10.drv

Thank you!  Exactly that.

Well,  'derivers' is not common -- from my poor English knowledge and
in the Guix vocabulary -- so please fin attached  a tiny patch that
mentions .drv in "guix gc --help" and 'delivers, derivation' to the
index.  I do not know if it makes sense but if I was too lazy to find
it, I bet that I am not the only one. ;-)


All the bets,
simon
