02/04: environment: Use 'with-build-handler'.


From: guix-commits
Subject: 02/04: environment: Use 'with-build-handler'.
Date: Wed, 25 Mar 2020 11:03:21 -0400 (EDT)

civodul pushed a commit to branch master
in repository guix.

commit c74f19d758c786d30ee238e3bc8c4e3f8893ba4b
Author: Ludovic Courtès <address@hidden>
AuthorDate: Wed Mar 25 15:01:15 2020 +0100

    environment: Use 'with-build-handler'.
    
    * guix/scripts/environment.scm (build-environment): Remove.
    (guix-environment): Wrap 'with-status-verbosity' in
    'with-build-handler'.  Remove 'dry-run?' conditional.  Use
    'built-derivations' instead of 'build-environment'.
