Nyx: NixOS System Management Toolkit

Nyx is a modular toolkit that simplifies and automates various NixOS system management tasks, from enhanced rebuilds to cleanup and shell customization.

---

Features

• Enhanced NixOS Rebuilds — via nyx-rebuild.nix
• Automated System Cleanup — via nyx-cleanup.nix
• Shell Customization & Tooling — banners and helpers via nyx-tool.nix
• All-in-One Integration — enable everything with a single import: nyx.nix

---

Dependencies

Tool / Service	Required	Notes
NixOS / Nix	✅	Nyx is designed for NixOS or compatible Nix environments
sudo access	✅	Needed for system-level operations
Home Manager	✅	Integrates via home.nix
Git	✅	Required for autoPush* features (must be a Git repo)
nix-output-monitor	✅	Automatically provided by Nyx

How It Works

• default.nix
  Importing the other Modules.

• nyx-tool.nix
  Sets up shell visuals (e.g. banners) and Zsh helpers.

• nyx-rebuild.nix
  Enhances nixos-rebuild with:

  • Git auto-push support
  • Optional code formatting before builds
  • Rebuild logging

• nyx-cleanup.nix
  Automates system cleanup and tracks logs (optionally pushes to GitHub).

• nyx-tui.nix
  Making a TUI for the other tools.

---

Quick Start

1. Add Nyx to your Flake

# flake.nix
{
  inputs.nyx.url = "github:Peritia-System/Nyx-Tools";

  outputs = inputs @ { nixpkgs, nyx, ... }:
  {
    nixosConfigurations.HOSTNAME = nixpkgs.lib.nixosSystem {
      modules = [ ./configuration.nix ];
    };
  };
}

2. Import Nyx into Home Manager

# home.nix
{
  config,
  inputs,
  ...
}:
{
  imports = [
    inputs.nyx.homeManagerModules.default
  ];
}

3. Enable Desired Modules

{
  nyx = {
    
    enable = true;
    inherit username nixDirectory;
    logDir = "/home/${username}/.nyx/logs";
    autoPush = false;

    nyx-rebuild = {
      enable = true;
      editor = "nvim";
      formatter = "alejandra";
      enableAlias = false;
      startEditor = false;
    };
    
    nyx-cleanup = {
      enable = true;
      keepGenerations = 5;
      enableAlias = false;
    };
    
    nyx-tool = {
      enable = true;
    };

    nyx-tui = {
      enable          = true;
      enableAlias     = false;
    };

  };
}

⚠️ Note: nixDirectory must be a full path to your flake repo (e.g., /home/${username}/NixOS/Nyx-Tools).

See other/example/example-home.nix for a working example.

4. Rebuild and you can use it:

# to just do a simple rebuild you can:
nyx-rebuild

# to see the available options: 
$ nyx-rebuild -h
nyx-rebuild [--repair] [--update]

  --repair   Stage & commit the nix_dir with "rebuild - repair <timestamp>"
             and remove any unfinished logs (Current-Error*.txt and rebuild-*.log
             that are not final nixos-gen_* logs).

  --update   Before rebuilding, update the flake in nix_dir using:
               nix flake update

# to cleanup old configurations:
nyx-cleanup

# And to see the other options:
nyx-cleanup -h
nyx-cleanup [--dry-run] [--keep N]

Prunes old *system* generations, runs GC (and store optimise), and tidies logs.

Options:
  --dry-run       Show actions without doing them.
  --keep N        Override configured generations to keep (default: 5).
  -h, --help      Show this help.


# For nyx-tui run simply 
nyx-tui

# or for a small startup animation
nyx-tui --pretty
