Instead, this patch keeps the original behavior of 'current-source-directory' macro and adds optional 'follow-symlinks?' argument to it. ;;; Copyright © 2024 Nigko Yerden * guix/utils.scm (absolute-dirname): Add 'follow-symlinks?' mandatory argument. (%guix-source-root-directory): Pass #f to 'absolute-dirname' 'follow-symlinks?' argument. (current-source-directory): Add 'follow-symlinks?' optional argument. * guix/gexp.scm (local-file): Pass #t to 'current-source-directory' 'follow-symlinks?' argument. * tests/gexp.scm ("local-file, load through symlink"): New test. Change-Id: Ieb30101275deb56b7436df444f9bc21d240fba59 --- Using of 'eval' in test from v4 is wrong. It does not play any role there. Most importantly it does not prevent spoiling of '%load-path' for the rest of 'tests/gexp.scm' module.
