From 9bb2b96aabdbb245c4a409e96b25df2954cfe385 Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Wed, 20 Feb 2013 23:41:24 +0100 Subject: ui: Factorize `show-what-to-build'. * guix/scripts/package.scm (guix-package)[show-what-to-build]: Move to.. * guix/ui.scm (show-what-to-build): ... here. Add a `store' parameter'. Adjust callers. * guix/scripts/build.scm (guix-build): Use it. Remove `req' and `req*' variables. --- guix/scripts/build.scm | 23 ++--------------------- guix/scripts/package.scm | 28 +--------------------------- guix/ui.scm | 29 +++++++++++++++++++++++++++++ 3 files changed, 32 insertions(+), 48 deletions(-) diff --git a/guix/scripts/build.scm b/guix/scripts/build.scm index 7863fb881b..fbd22a9e29 100644 --- a/guix/scripts/build.scm +++ b/guix/scripts/build.scm @@ -241,31 +241,12 @@ Build the given PACKAGE-OR-DERIVATION and return their output paths.\n")) (package-derivation (%store) p sys)))) (_ #f)) opts)) - (req (append-map (lambda (drv-path) - (let ((d (call-with-input-file drv-path - read-derivation))) - (derivation-prerequisites-to-build (%store) d))) - drv)) - (req* (delete-duplicates - (append (remove (compose (cut valid-path?
