[Nix-dev] Overriding python with python3 in vim_configurable.customize

[Ben Zhang]

Thanks everyone for your input! I ended up using zimbatm’s method and made a python3 version of `vim_configurable` using `vimUtils.makeCustomizable`. Now it’s working great!

My current `vim-config/default.nix`:

```
{ pkgs }:

let
  my_plugins = import ./plugins.nix { inherit (pkgs) vimUtils fetchFromGitHub; };
  configurable_nix_path = "${<nixpkgs>}/pkgs/applications/editors/vim/configurable.nix";
  my_vim_configurable = with pkgs; vimUtils.makeCustomizable (callPackage configurable_nix_path {
    inherit (darwin.apple_sdk.frameworks) CoreServices Cocoa Foundation CoreData;
    inherit (darwin) libobjc cf-private;

    features = "huge"; # one of  tiny, small, normal, big or huge
    lua = pkgs.lua5_1;
    gui = config.vim.gui or "auto";
    python = python3;

    # optional features by flags
    flags = [ "python" "X11" ];
  });

in with pkgs; my_vim_configurable.customize {
  name = "vim";
  vimrcConfig = {
    customRC = ''
      syntax on
      “...
    '';

    vam.knownPlugins = vimPlugins // my_plugins;
    vam.pluginDictionaries = [
      { names = [
        "ctrlp"
        # ...
      ]; }
    ];
  };
}
```
