[Ludovic Courtès]

Hi,

Philip Munksgaard <philip@munksgaard.me> skribis:

> Fixes <https://issues.guix.gnu.org/48701>.
>
> * guix/import/cabal.scm (make-cabal-parser): Modify.
> (is-common): New variable.
> (lex-common): New procedure.
> (is-id): Modify.
> (eval-cabal): Modify.
> * tests/hackage.scm ("hackage->guix-package test cabal import") New test.

Applied with the change below (‘cut’ is for procedures but ‘match’ is a
macro).

Thanks!

Ludo’.
