Guix environment will work for other use cases I have, but not for this one. Because once I exit an environment the packages I installed there are not kept around, but I want the packages specified in the manifest to be added to the user profile. Also, I can't do just "guix environment -m FILE", I have to provide at least one package as an argument for PACKAGES..., and that would not make sense in my use case. > if you are willing to hack a little bit, Ricardo Wurmus wrote a little > Guile script that helps convert a profile manifest (e.g. your default > profile) to a manifest.scm file: > > http://lists.gnu.org/archive/html/guix-devel/2018-10/msg00023.html > That gave me ideas. I looked at the (guix profiles) module and wrote a manifest like this for testing: ########## (use-modules (gnu packages) (guix profiles) (ice-9 match) (ice-9 pretty-print)) ;;; HELPER PROCEDURES ;;; ================= (define (profile-manifest->package-names) "Return a list with the names of the packages installed in the user profile (see %user-profile-directory in the (guix profiles) module)." (map manifest-entry-name (manifest-entries (profile-manifest %user-profile-directory)))) ;;; PACKAGES ;;; ======== (define packages (append (profile-manifest->package-names) (list "alex4" "endless-sky"))) ;;; MANIFEST ;;; ======== (packages->manifest (map specification->package packages)) ########## I think that's what I wanted. Thanks, Giovanni :)
