# dots

This repository contains my dotfiles and a Nix flake that supports multiple hosts (machines) with a shared base and per-host configuration.

## Nix Configuration

The Nix configuration is located in the `nix/` directory. It uses a shared Home Manager configuration for all hosts, while allowing host-specific NixOS or package settings.

### Structure

- `nix/flake.nix`: Entry point, defines hosts and helpers.
- `nix/home/`: Shared Home Manager configuration (packages, shell, GNOME settings).
- `nix/hosts/`: Host-specific NixOS configurations.

### Adding New Hosts

#### NixOS Hosts
1. Create a directory in `nix/hosts/<hostname>/`.
2. Add `configuration.nix`, `hardware-configuration.nix`, and `packages.nix` there.
3. Add the host to `nixosConfigurations` in `nix/flake.nix`:
   ```nix
   limgrave = mkNixos "limgrave" [
     nix-snapd.nixosModules.default
     autofirma-nix.nixosModules.default
   ];
   ```

#### Non-NixOS Hosts (e.g., Ubuntu)
1. Add the host to `homeConfigurations` in `nix/flake.nix`:
   ```nix
   "catalin@ubuntu" = mkHome "ubuntu" "catalin" [ ];
   ```
   *Note: `mkHome` takes `hostname`, `username`, and additional modules.*

### Building and Applying

#### NixOS
Run from the root of the repository:
```bash
sudo nixos-rebuild switch --flake .#hostname
```

#### Non-NixOS (Home Manager)
Run from the root of the repository:
```bash
home-manager switch --flake ./nix#user@hostname
```
