I'll probably get RTFM'ed once again, but at least I tried to search first...
It looks like this : https://www.gnu.org/software/guix/manual/guix.html#Building-from-Git is intended for people willing to hack on guix itself, but I want to hack at the package's definitions... I want to test the pythondialog patch I posted in te other thread... How do you try modifications to packages that are already in the repo ? Is GUIX_PACKAGE_PATH completely overriding the repo, so I can just copy the file I want to test in there, modify it, then build ? -- Vincent Legoll
