Just a quick follow-up to [Building 0.19 from source?](https://discourse.elm-lang.org/t/building-0-19-from-source/3769), since I missed the ten-day window to reply in-line:
You might have a look at [the `nix` expression for `elm`](https://github.com/NixOS/nixpkgs/tree/master/pkgs/development/compilers/elm). It declares all the proper versions of `ghc`, the various Haskell libs, etc. needed for a successful build.
If you’re interested in building ancillary elm tools with `nix` as well, see [Elm tooling for Nix and NixOS users](https://discourse.elm-lang.org/t/elm-tooling-for-nix-and-nixos-users/3641).

Oh, and tagging @Joey_Eremondi so he’ll see this. 🙂

Related to that I’m currently working (waiting for merge) on integration of elm tooling directly yo nixpkgs. I would like to continue improving the state of elm with nix further. I have some PRs to elm2nix opened at the moment as well incrising the support of elm features and in the future I would also like the make nixpkgs compiler easily configurable so anyone who needs or wants can specify compiler version with certain patches applied. I think it might be reasonable middlegroud between not forcing the upstream to merge every patch and providing hotfixes.

You can do that pretty easily with `overrideAttrs` already—what other additions are needed?

All I thought about is a bit of sugar which will make it a tiny bit simpler for newcomers. We’ll see I haven’t tryied anything still. Probably something like `elmWithPatches....`
