Re: [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 = 
"${}/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"
        # ...
      ]; }
    ];
  };
}
```

Another potential option would be using package overrides [1] to pass
python3 as python to the vim package — something like

   packageOverrides = pkgs: {
  vim = pkgs.vim.override { python = pkgs.python3 };
   };

[zimbatm]

Look into pkgs/top-level/all-packages.nix. I would start by copying the
definition of vim_configurable from there and set the python argument.

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

[Ben Zhang]

From the source code, it doesn’t seem to accept a python argument 
(https://github.com/nicknovitski/nixpkgs/blob/master/pkgs/misc/vim-plugins/vim-utils.nix#L291-L295).
 Is there another way to override `python` with `python3` 
(https://github.com/NixOS/nixpkgs/pull/8125#issuecomment-169471686)?

Thanks,

Ben

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

[zimbatm]

The "with" keyword binds the designated attrset pairs into scope. It
doesn't override other called function variables though.

Do you know if the customise function accepts a python argument as an input?
