Hello,
I'm trying to understand which package(s) depends on some other
package,
kind of the reverse of what guix graph does (I think).
I think that `guix refresh --list-dependent foo` is what you are
asking
for, or at least it's close. We use it to learn what will need to be
rebuilt when upgrading foo.
Not really what I want to know:
# guix refresh --list-dependent inkscape
Building the following 5 packages would ensure 10 dependent packages
are rebuilt: frescobaldi-2.19.0 solfege-3.22.2 simple-scan-3.19.91
termite-11 hydra-20150407.4c0e3e4
None of those are installed, but inkscape is pulled in by something
which I want to know
Is there no other way to get that information ?
Something like (mildly tested):
(use-modules (guix packages)
(gnu packages)
(gnu packages inkscape)
(srfi srfi-1)
(srfi srfi-26))
(fold-packages
(lambda (package _)
(when (any (cut eq? <> inkscape)
(map second (package-direct-inputs package)))
(format #t "~a depends on inkscape~%"
(package-full-name package))))
#t)
which, when run, results in:
"dblatex-0.3.5 depends on inkscape"
