Re: Cookbook recipe from "The Repository as a Channel" section does not work for Guix with properly configured GUILE_LOAD_PATH

[Nigko Yerden]

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
