From 1fafc383b1f04fcdaa49941f5bb64ac3008cfad8 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ludovic=20Court=C3=A8s?= Date: Fri, 18 Jan 2019 10:01:37 +0100 Subject: inferior: 'gexp->derivation-in-inferior' honors EXP's load path. Previously the imported modules and extensions of EXP would be missing from the load path of 'guix repl'. * guix/inferior.scm (gexp->derivation-in-inferior)[script]: New variable. [trampoline]: Write (primitive-load #$script) to PIPE. Add #$output. * tests/channels.scm ("channel-instances->manifest")[depends?]: Check for requisites rather than direct references. Adjust callers accordingly. --- guix/inferior.scm | 13 ++++++++++--- 1 file changed, 10 insertions(+), 3 deletions(-) (limited to 'guix/inferior.scm') diff --git a/guix/inferior.scm b/guix/inferior.scm index 4dfb242e44..9f19e7d316 100644 --- a/guix/inferior.scm +++ b/guix/inferior.scm @@ -491,6 +491,10 @@ PACKAGE must be live."
