[Haskell-cafe] GHCJS Bad first impression

[Peter Simons]

Hi David,

 > cabal2nix doesn't generate nix expressions that are sensitive to ghcjs.

the expressions in Nixpkgs target GHC 8.0.x, not GHCJS. If you want
cabal2nix to generate expressions for GHCJS instead, then you'll just
have to run it with the flag "--compiler=ghcjs". Builds generated by the
Nix function haskell.packages.ghcjs.callHackage do this automatically.

Best regards,
Peter
