From 91cf9d17f02fdf82424c7f2dda2c3651f992bf13 Mon Sep 17 00:00:00 2001 From: Maxim Cournoyer Date: Fri, 22 Jan 2021 09:15:46 -0500 Subject: build/python: Always add the install prefix to the Guix PYTHONPATH. This is to remove the need for common boilerplate code in check phase overrides. * guix/build/python-build-system.scm (add-installed-pythonpath): Streamline. This phase depends on the presence of a "python" input; thus GUIX_PYTHONPATH is guaranteed to be defined. Update doc. (add-install-to-pythonpath): New phase. (%standard-phases): Order it before the check phase. --- guix/build/python-build-system.scm | 18 ++++++++++-------- 1 file changed, 10 insertions(+), 8 deletions(-) (limited to 'guix/build') diff --git a/guix/build/python-build-system.scm b/guix/build/python-build-system.scm index 8e359398e1..9f5fad7faf 100644 --- a/guix/build/python-build-system.scm +++ b/guix/build/python-build-system.scm @@ -6,7 +6,7 @@ ;;; Copyright © 2016 Hartmut Goebel ;;; Copyright © 2018 Ricardo Wurmus ;;; Copyright © 2018 Arun Isaac -;;; Copyright © 2019, 2020 Maxim Cournoyer +;;; Copyright © 2019, 2020, 2021 Maxim Cournoyer ;;; Copyright © 2020 Jakub Kądziołka ;;; Copyright © 2020 Efraim Flashner ;;; @@ -170,13 +170,14 @@ (string-append out "/lib/python" (python-version python) "/site-packages"))) (define (add-installed-pythonpath inputs outputs) - "Add the Python site-package of OUTPUT to GUIX_PYTHONPATH.
