From 45d46223f92b0933aaf9b1392a21d09eaa1e2881 Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Mon, 17 Jun 2019 16:06:27 +0200 Subject: utils: Add 'invoke/quiet'. * gnu/build/bootloader.scm (G_): Remove. (open-pipe-with-stderr, invoke/quiet): Move to... * guix/build/utils.scm: ... here. Use 'let-values' instead of 'define-values' because Guile 2.0 (the bootstrap Guile) doesn't know about 'define-values'. * po/guix/POTFILES.in: Remove gnu/build/bootloader.scm, and add guix/build/utils.scm. * tests/build-utils.scm: Remove import of (gnu build bootloader). --- gnu/build/bootloader.scm | 62 +----------------------------------------------- 1 file changed, 1 insertion(+), 61 deletions(-) (limited to 'gnu') diff --git a/gnu/build/bootloader.scm b/gnu/build/bootloader.scm index c5febcde1e..9570d6dd18 100644 --- a/gnu/build/bootloader.scm +++ b/gnu/build/bootloader.scm @@ -18,15 +18,8 @@ ;;; along with GNU Guix.
