Hello, I have questions about installing/deleting packages using guile repl. I know it is possible to ‘(guix-package "--install" "guile-2.0.11")’, but is there an easy way to install an output of an exact _package object_? I mean not any "guile" but #<package guile-2.0.11 ...>.
I think ‘(guix-package "--install-from-expression" ...)’ is also not sufficient as it always (?) installs “out”. If I understand correctly a lot of stuff should be done to perform such actions properly: at first the new manifest is created from the current one by adding/removing entries (created from packages) for installation/deletion, then the derivations are built and symlinks are updated. There is a lot of code in “guix/scripts/package.scm” to do all that stuff and unfortunately not much is exported from this module (“package->manifest-entry” from “options->installable” would be very useful for example), and I think trying to include this code in the helper scheme file for guix.el is not right (besides my scheme foo is weak and I'm not sure I can do that successfully) that's why I ask about an easier way. Thanks, Alex
