Dear Guix experts,
I wonder if there is a straightforward way to find the store path
corresponding to a package, assuming that the package actually is in the
store. I don't care if it's done via the CLI or via Guile code.
Use case: Looking at the files inside a package. What I do now is "ls
/gnu/store/*<package-name>*", but that usually lists many variants of
the package, and I don't know which of them actually is the current one.
I came up with some Guile code that does the job:
(define (store-path specification)
(let*-values (((package output)
(specification->package+output specification))
((entry)
(package->manifest-entry package output))
((l-entry)
(with-store store
(run-with-store store
(lower-manifest-entry entry (%current-system))))))
(manifest-entry-item l-entry)))
but it also downloads/builds the package if it's not yet in the store,
which is not what I want. In fact, I don't care what happens then the
package is not in the store. Returning a non-existing path is fine,
as is raising an error or returning #f.
Another attempt is "guix package –-list-installed", but this works only
for packages installed in a profile. I am shifting more and more to
on-the-fly environments, meaning that many packages in my store belong
to no profile.
Cheers,
Konrad.
