[Nix-dev] Could not find module `Yi' (haskell editor)

[Patrick Wheeler]

The default install mechanism:

nix-env -iA nixos.pkgs.haskellPackages.yi

does not work well with yi and similar packages like mueval, hint(yi
depends on this), ghc api, and others. Instead use the `ghcWithPackages`
method found on the wiki page:
https://nixos.org/wiki/Haskell#Local_use_via_Nixpkgs_config

Here is added to myHaskellPackages

    yiEnv = haskellPackages.ghcWithPackages (self : [

      self.yi

      # add more packages here

    ]);

How to set up and maintain custum packages:

https://nixos.org/wiki/Haskell#Maintaining_your_own_set_of_additional_Haskell_packages

I do not know if it is out of date or not if it does not work let me know
and I will pull what I have in config currently.
