Hi N0lim, N0lim <0s7n888884@gmail.com> skribis: > I want to add a Haskell development package Nice. Could you turn it into a patch for Guix proper? Please take a look at and do ask here or on #guix on IRC if anything’s unclear. In particular: > (define-module (n0lim ghc-cryptohash-sha512) … packages in Guix are in the (gnu packages …) name space. You’ll find that one of the gnu/packages/haskell*.scm files is probably suitable for this package. Thanks in advance! Ludo’.
