Hello Attila Lendvai,
Thank you very much for your hints and references! Indeed I was puzzled by
weird behavior of 'current-filename'. I wrote another alternative
using '(module-filename (current-module))' based on
https://issues.guix.gnu.org/55464
See alt2 branch of [1].
This variant does not need wrapping directory for the package file, and
has the same file structure as the main branch of [1]. The variable
(define package-dir
(dirname
(canonicalize-path
(search-path %load-path
(module-filename (current-module))))))
is bounded to the current directory of 'test-repo-package.scm', so
the 'source' field of the package is
(local-file (string-append package-dir "/../..")
"test-repo-checkout"
#:recursive? #t
#:select? vcs-file?))
It seems to work even without macro wrapper.
Regards,
Nigko
