civodul pushed a commit to branch master
in repository guix.
commit 95cd4971d07fe312a4e0d21b72e7bf1bba493753
Author: Ludovic Courtès <address@hidden>
Date: Tue Mar 8 11:38:46 2016 +0100
packages: Support the deprecated "NAME-VERSION" syntax.
Fixes a typo introduced in 1b846da8c372bee78851439fd9e72b2499115e5a that
would lead to a backtrace when using the deprecated syntax.
* gnu/packages.scm (%find-package): Turn the first argument to
'call-with-values' into a thunk. Use #:select instead of '@' to select
the right 'package-name->name+version' procedure.
