Nix Flakes
----------
Home Manager includes a `flake.nix` file for compatibility with [Nix Flakes][]
for those that wish to use it as a module. A bare-minimum `flake.nix` would be
as follows:
```nix
{
description = "NixOS configuration";
inputs = {
nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
home-manager.url = "github:nix-community/home-manager";
# nix-darwin.url = "github:lnl7/nix-darwin";
};
outputs = inputs@{ home-manager, nixpkgs, ... }: {
nixosConfigurations = {
hostname = nixpkgs.lib.nixosSystem {
system = "x86_64-linux";
modules = [
./configuration.nix
home-manager.nixosModules.home-manager
{
home-manager.useGlobalPkgs = true;
home-manager.useUserPackages = true;
home-manager.users.jdoe = import ./home.nix;
# Optionally, use home-manager.extraSpecialArgs to pass
# arguments to home.nix
}
];
};
};
# You do not need this unless you are using the nix-darwin project
darwinConfigurations = {
hostname = inputs.nix-darwin.lib.darwinSystem {
system = "x86_64-darwin";
modules = [
./configuration.nix
home-manager.darwinModules.home-manager
{
home-manager.useGlobalPkgs = true;
home-manager.useUserPackages = true;
home-manager.users.jdoe = import ./home.nix;
}
];
};
};
};
}
```
The Home Manager configuration is then part of the NixOS/Darwin configuration
and is automatically rebuilt with the system when using the appropriate command
for the system, such as `nixos-rebuild switch --flake <path>` for NixOS,
and `darwin-rebuild switch --flake <path>` with nix-darwin.
If you are not using NixOS you can place the following flake in
`~/.config/nixpkgs/flake.nix` to load your standard Home Manager
configuration:
```nix
{
description = "A Home Manager flake";
inputs = {
nixpkgs.url = "github:nixos/nixpkgs/nixpkgs-unstable";
home-manager.url = "github:nix-community/home-manager";
home-manager.inputs.nixpkgs.follows = "nixpkgs";
};
outputs = inputs: {
homeConfigurations = {
jdoe = inputs.home-manager.lib.homeManagerConfiguration {
system = "x86_64-linux";
homeDirectory = "/home/jdoe";
username = "jdoe";
configuration.imports = [ ./home.nix ];
};
};
};
}
```
Note, the Home Manager library is exported by the flake under
`lib.hm`.
When using flakes, switch to new configurations with
`home-manager switch --flake <path>`.
