With this change, each substitute occupies a single line of output (instead of two) when using '-v1', the default for 'guix package' & co. * guix/status.scm (print-build-event): Add #:print-urls? and honor it. (print-build-event/quiet): Pass #:print-urls? #f. (print-build-event/quiet-with-urls): New procedure. (logger-for-level): Add case for LEVEL 2. * doc/guix.texi (Common Build Options): Adjust '--verbosity' documentation.

|
||
;;; This module provides facilities to track the status of ongoing builds and
|
||
;;; downloads in a given session, as well as tools to report about the current
|
||
;;; status to user interfaces. It does so by analyzing the output of
|
||
;;; 'current-build-output-port'. The build status is maintained in a
|
||
;;; <build-status> record.
