# Users

Users are a special case of [profiles](profiles.md) that define system
users and [home-manager][home-manager] configurations. For your convenience,
home manager is wired in by default so all you have to worry about is declaring
your users. For a fully fleshed out example, check out the developers personal
[branch](https://github.com/divnix/devos/tree/nrd/users/nrd/default.nix).

## Basic Usage

`users/myuser/default.nix`:

```nix
{ ... }:
{
  users.users.myuser = {
    isNormalUser = true;
  };

  home-manager.users.myuser = {
    programs.mpv.enable = true;
  };
}

```

## Home Manager

Home Manager support follows the same principles as regular nixos configurations,
it even gets its own namespace in your `flake.nix` as `home`.

All modules defined in [user modules][modules-list] will be imported to
Home Manager.
User profiles can be collected in a similar fashion as system ones into a `suites`
argument that gets passed to your home-manager users.

### Example

`flake.nix`

```nix
{
  home.users.nixos = { suites, ... }: {
    imports = suites.base;
  };
}
```

## External Usage

You can easily use the defined home-manager configurations outside of NixOS
using the `homeConfigurations` flake output.

This is great for keeping your environment consistent across Unix-like systems,
including macOS.

### From within the projects devshell:

```sh
# builds the pub-solar user defined in the PubSolarOS host
nix build '.#homeConfigurations."pub-solar@PubSolarOS".activationPackage'

# build and activate
nix build '.#homeConfigurations."pub-solar@PubSolarOS".activationPackage' && ./result/activate && unlink result
```

### Manually from outside the project:

```sh
# build
nix build "github:divnix/devos#homeConfigurations.nixos@NixOS.home.activationPackage"

# activate
./result/activate && unlink result
```
