[Haskell-cafe] GHCJS Bad first impression

Tue Nov 1 02:27:02 UTC 2016

Zachary,

The ghcjs-dom package on nixpkgs is pretty badly broken. This is because
cabal2nix doesn't generate nix expressions that are sensitive to ghcjs.
Therefore, you have to override derivations before you even begin.

To do this create the directory ~/.nixpkgs with file config.nix
(~/.nixpkgs/config.nix).

Then paste the contents of this config.nix [1] into your local file system,
then try the previous script again:

> nix-shell -p "haskell.packages.ghcjs.ghcWithPackages (pkgs: with pkgs;
[ghcjs-base ghcjs-dom])”

[1] https://gist.github.com/dmjio/380f8d8729f7f81be48ffdddb3fb1de0

Regards,

Dave
