civodul pushed a commit to branch core-updates
in repository guix.
commit ff992fcfaf8455910b4bb5e02861fe9ae3dfd974
Author: Ludovic Courtès <ludo@gnu.org>
AuthorDate: Wed Jun 30 16:00:37 2021 +0200
import: print: Emit new-style package inputs when possible.
* guix/import/print.scm (redundant-input-labels?): New procedure.
(package->code)[package-lists->code]: Rename to...
[inputs->code]: ... this. When 'redundant-input-labels?' returns true,
emit label-less inputs. Adjust callers to new name.
* tests/print.scm (pkg-with-inputs): Adjust accordingly.
