* guix/import/cpan.scm (cpan-name->downstream-name) (cran-dependency->upstream-input, cran-module-inputs): New procedures. (cpan-module->sexp)[guix-name, convert-inputs]: Remove. [maybe-inputs]: Adjust to deal with <upstream-input>. Use 'cpan-name->downstream-name' instead of 'guix-name'. Add call to 'cpan-module-inputs' and adjust calls to 'maybe-inputs'. No longer emit input labels. * tests/cpan.scm ("cpan->guix-package"): Adjust test accordingly. --- guix/import/cpan.scm | 98 +++++++++++++++++++++++++------------------- tests/cpan.scm | 7 +--- 2 files changed, 58 insertions(+), 47 deletions(-)
