I'm just getting started with NixOS, and I'm trying to us home-manager to declaratively control which packages I have installed and deploy their configurations to my home directory.
I told home-manager to install vim_configurable
# ~/.config/nixpkgs/home.nix
{ config, pkgs, ... }:
{
home.packages = [
pkgs.vim_configurable
#...
]
#...
Which worked fine, but I ran into errors when I tried to use program.vim to configure it:
#...
programs.vim = {
enable = true;
settings = {
expandtab = true;
tabstop = 2;
};
};
Running home-manager switch gave me an error due to conflicting versions of gvimdiff

I'm guessing this is because programs.vim.enable = true instructs home-manager to add the system vim, or something, and that's conflicting?
Removing enable = true got rid of the error, but none of the configuration settings seemed to come through, which made specifying the programs.vim block at all rather pointless.
Am I doing something wrong? Should this work, or does this sort of configuration expect me to have installed packages by updating /etc/nixos/configuration.nix instead?
