Usage

As a Flake Input

{
  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixos-25.05";
    nix-modules = {
      url = "github:yourusername/nix-modules";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { nixpkgs, nix-modules, ... }: {
    # Your config here
  };
}

Import Individual Modules

{ inputs, ... }:
{
  imports = [
    inputs.nix-modules.homeManagerModules.neovim
    inputs.nix-modules.homeManagerModules.tmux
    inputs.nix-modules.homeManagerModules.git
    inputs.nix-modules.homeManagerModules.shell
    inputs.nix-modules.homeManagerModules.terminal
  ];

  programs.andrevim.enable = true;
  
  # Configure git signing per-host
  programs.git.signing = {
    key = "YOUR_GPG_KEY";
    signByDefault = true;
  };
}

Standalone Package

Run neovim directly without home-manager:

nix run github:yourusername/nix-modules#neovim
