# Example NixOS Configuration for lidarr-mb-gap
# ============================================================================
# 
# Choose one of the examples below based on your setup:
# - Example 1: Using flake input (recommended)
# - Example 2: Using source path directly
# - Example 3: Minimal configuration
#
# ============================================================================

# ============================================================================
# EXAMPLE 1: Using Flake Input (Recommended)
# ============================================================================
# 
# First, add to your flake.nix inputs:
#   inputs.lidarr-mb-gap.url = "path:/path/to/lidarr-musicbrainz";
#   # or
#   inputs.lidarr-mb-gap.url = "github:yourusername/lidarr-musicbrainz";
#
# Then in your NixOS configuration:

{ config, pkgs, inputs, ... }:

{
  imports = [
    inputs.lidarr-mb-gap.nixosModules.lidarr-mb-gap
  ];

  services.lidarr-mb-gap = {
    enable = true;
    
    # Reference the package from the flake
    package = inputs.lidarr-mb-gap.packages.${pkgs.system}.lidarr-mb-gap;
    
    # Report settings
    reportDir = "/var/lib/lidarr-mb-gap/reports";
    envFile = "/var/lib/lidarr-mb-gap/.env";
    runInterval = "daily";  # Options: "daily", "hourly", "*-*-* 02:00:00"
    
    # Optional: Auto-sync to VPS
    syncToVPS = true;
    vpsHost = "user@vps";  # Your SSH host alias or "user@vps.example.com"
    vpsPath = "/var/www/html";
    
    # SSH configuration for VPS sync
    sshKeyFile = "/var/lib/lidarr-mb-gap/.ssh/id_ed25519";
    sshKnownHosts = {
      vps = {
        hostNames = [ "vps" "vps.example.com" "1.2.3.4" ];  # All possible hostnames/IPs
        # Get this with: ssh-keyscan -t ed25519 vps.example.com
        publicKey = "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAI...";
      };
    };
  };
}

# ============================================================================
# EXAMPLE 2: Using Source Path (Non-Flake)
# ============================================================================
# 
# If you're not using flakes, import the module directly:

{ config, pkgs, ... }:

{
  imports = [
    /path/to/lidarr-musicbrainz/nixos/lidarr-mb-gap.nix
  ];

  services.lidarr-mb-gap = {
    enable = true;
    
    # Build from source
    src = /path/to/lidarr-musicbrainz/src;
    
    # Report settings
    reportDir = "/var/lib/lidarr-mb-gap/reports";
    envFile = "/var/lib/lidarr-mb-gap/.env";
    runInterval = "daily";
    
    # Optional: Auto-sync to VPS
    syncToVPS = true;
    vpsHost = "user@vps";
    vpsPath = "/var/www/html";
    sshKeyFile = "/var/lib/lidarr-mb-gap/.ssh/id_ed25519";
    sshKnownHosts = {
      vps = {
        hostNames = [ "vps" "vps.example.com" ];
        publicKey = "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAI...";
      };
    };
  };
}

# ============================================================================
# EXAMPLE 3: Minimal Configuration (No VPS Sync)
# ============================================================================

{ config, pkgs, inputs, ... }:

{
  imports = [
    inputs.lidarr-mb-gap.nixosModules.lidarr-mb-gap
  ];

  services.lidarr-mb-gap = {
    enable = true;
    package = inputs.lidarr-mb-gap.packages.${pkgs.system}.lidarr-mb-gap;
    # All other options use defaults
  };
}

# ============================================================================
# SETUP STEPS AFTER ADDING CONFIGURATION
# ============================================================================
#
# 1. Create the .env file:
#    sudo mkdir -p /var/lib/lidarr-mb-gap
#    sudo nano /var/lib/lidarr-mb-gap/.env
#
#    Add:
#    LIDARR_URL=http://your-lidarr-instance:8686
#    LIDARR_API_KEY=your-api-key-here
#    SAMBL_URL=https://sambl.lioncat6.com
#    MAX_ARTISTS=0
#
# 2. Set permissions:
#    sudo chown -R lidarr-mb-gap:lidarr-mb-gap /var/lib/lidarr-mb-gap
#    sudo chmod 600 /var/lib/lidarr-mb-gap/.env
#
# 3. If using VPS sync, set up SSH keys:
#    sudo -u lidarr-mb-gap ssh-keygen -t ed25519 -f /var/lib/lidarr-mb-gap/.ssh/id_ed25519 -N ""
#    sudo -u lidarr-mb-gap cat /var/lib/lidarr-mb-gap/.ssh/id_ed25519.pub | ssh user@vps "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys"
#    ssh-keyscan -t ed25519 vps.example.com  # Use output in sshKnownHosts
#
# 4. Rebuild:
#    sudo nixos-rebuild switch
#
# 5. Test:
#    sudo systemctl start lidarr-mb-gap
#    sudo journalctl -u lidarr-mb-gap -f
#
