Subject: [bug#55680] [PATCH] packages: Add 'specifications->packages'.
Date: Fri, 27 May 2022 13:13:28 -0400 [thread overview]
Message-ID: <20220527171328.18174-1-antero@mailbox.org> (raw)
* gnu/packages.scm (specifications->packages): New procedure.
* guix/scripts/home/import.scm (manifest+configuration-files->code): Use it.
---
Users of 'guix home' may not know the Scheme 'map' and 'compose' procedures.
However 'guix home import' creates boilerplate with those procedures.
Add 'specificiations->packages' procedure to make it more like a guix manifest.
'specfications->packages' can also help with guix system declarations.
