Install elm 0.16 on nixos

Last I checked elm had made it into nixpkgs (at least in unstable), but its only at 0.14.  With the flurry of blog posts lately about 0.16, 0.14 is not going to cut it!  Luckily installing 0.16 is pretty easy (except for the shell.nix perhaps):

> cd <where I keep code>
> mkdir elmthings
> cd elmthings

Then (just like with 0.15.1), make an shell.nix file that looks like this:

nixpkgs ? import  {}, compiler ? "ghc7102" }:
  inherit (nixpkgs) pkgs;
  cabal = pkgs.haskell.packages.${compiler}.cabal-install;
  ghc = pkgs.haskell.packages.${compiler}.ghcWithPackages (ps: with ps; [
          monad-par mtl
pkgs.stdenv.mkDerivation {
  name = "my-haskell-env-0";
  buildInputs = [ ghc cabal pkgs.zlib ];
  shellHook = "eval $(egrep ^export ${ghc}/bin/ghc)";

Then its just following the directions from the elm site:

[pr06lefs@nixosthe1:~/code/elmthings]$ nix-shell
[nix-shell:~/code/elmthings]$ curl > BuildFromSource.hs
[nix-shell:~/code/elmthings]$ runhaskell BuildFromSource.hs 0.16

If all goes well, the executables end up in the following directory. This directory should be added to your path.


[nix-shell:~/code/elmthings/Elm-Platform/0.16/.cabal-sandbox/bin]$ ls
aeson-pretty elm elm-make elm-package elm-reactor elm-repl glsl-pprint
