* ABOUT
Setting up the document.  Also this should allow me to set up variables, and
other functions.
- Global version number so NixOS and Home-Manager are in sync
- The unstable part allows me to build packages from the unstable channel by
  prepending "unstable" to a package name.
- The next part creates a simple build of some of my simple scripts, turning
  them into binaries which then I can integrate into the nix-store as well as
  declared systemd units.

* DECLARATION
Here I will declare the dependencies and variables that will be used multiple
times through the config file, such as the current version of NixOS,
repositories and even some scripts that will be reused on systemd
configurations.

** VARIABLES

#+begin_src nix
{ config, pkgs, ... }:
let
  version = "23.05";
  myEmail = "CaptainJawZ@outlook.com";
  myName = "Danilo Reyes";
  home-manager = builtins.fetchTarball "https://github.com/nix-community/home-manager/archive/release-${version}.tar.gz";
  unstable = import
    (builtins.fetchTarball "https://github.com/nixos/nixpkgs/tarball/master") {
    config = config.nixpkgs.config;
  };
  jawzManageLibrary = pkgs.writeScriptBin
    "manage-library" (builtins.readFile ../scripts/manage-library.sh);
  jawzTasks = pkgs.writeScriptBin
    "tasks" (builtins.readFile ../scripts/tasks.sh);
in
{ # Remember to close this bracket at the end of the document
#+end_src

** IMPORTS
These are files and modules which get loaded onto the configuration file, in the
future I may segment this file into different modules once it becomes too
cluttered, for example, I may create a module for systemd units.

#+begin_src nix
imports = [
  ./hardware-configuration.nix
  ./servers.nix
  # ./openldap.nix
  # <agenix/modules/age.nix>
  (import "${home-manager}/nixos")
];
#+end_src

* SYSTEM CONFIGURATION
** NETWORKING
At the moment, I don't have a wireless card on this computer, however as I build
a new system, such setting may come in handy.

Pick *ONLY ONE* of the below networking options.
- *wireless.enable* enables wireless support via wpa_supplicant.
- *NetworkManager* it's the default of GNOME, and easiest to use and integrate.

#+begin_src nix
networking = {
  hostName = "workstation";
  networkmanager.enable = true;
  extraHosts = ''
               192.168.1.64 battlestation
               '';
  firewall = let
    open_firewall_ports = [
      6969 # HentaiAtHome
      25152 # ssh
      51413 # torrent sedding
      9091 # qbittorrent
      2049 # nfs
    ];
    open_firewall_port_ranges = [
      { from = 1714;  to = 1764; } # kdeconnect
    ];
    in
    {
    enable = true;
    allowedTCPPorts = open_firewall_ports;
    allowedUDPPorts = open_firewall_ports;
    allowedTCPPortRanges = open_firewall_port_ranges;
    allowedUDPPortRanges = open_firewall_port_ranges;
  };
};
#+end_src

** TIMEZONE & LOCALE
For some reason, useXkbConfig throws an error when building the system, either
way it is an unnecessary setting as my keyboards are the default en_US, only
locale set to Canadian out because I prefer how it displays the date.

#+begin_src nix
time.timeZone = "America/Mexico_City";

i18n = {
  defaultLocale = "en_CA.UTF-8";
  extraLocaleSettings = {
    LC_MONETARY = "es_MX.UTF-8";
  };
};
console = {
  font = "Lat2-Terminus16";
  keyMap = "us";
  #  useXkbConfig = true; # use xkbOptions in tty.
};
#+end_src

* GNOME
At the time of writing this file, I require of X11, as the NVIDIA support for
Wayland is not perfect yet.  At the time being, the ability to switch through
GDM from Wayland to XORG, it's pretty handy, but in the future these settings
will require an update.

Sets up GNOME as the default desktop environment, while excluding some
undesirable packages from installing.

#+begin_src nix
services = {
  xserver = {
    enable = true;
    displayManager.defaultSession = "xfce";
    desktopManager = {
      xfce.enable = true;
      xterm.enable = false;
    };
    layout = "us";
    libinput.enable = true; # Wacom required?
  };
};
#+end_src

* SOUND
In order to avoid issues with PipeWire, the wiki recommends to disable /sound.enable/
This is a basic PipeWire configuration, in the future stuff like Bluetooth or
latency will require expanding these settings.

#+begin_src nix
hardware.pulseaudio.enable = false;
sound.enable = false;
services.pipewire = {
  enable = true;
  alsa.enable = true;
  alsa.support32Bit = true;
  pulse.enable = true;
};
#+end_src

* SECURITY
Disabled password in sudo for commodity, but this is obviously not recommended,
regarding rkit, that setting enables pipewire to run with real-time
capabilities.  And lastly, the acme settings are for signing certificates.
#+begin_src nix
security = {
  rtkit.enable = true;
  sudo = {
    enable = true;
    wheelNeedsPassword = false;
  };
  acme = {
    acceptTerms = true;
    defaults.email = "${myEmail}";
  };
};
#+end_src

* NIXPKGS
Allow non-free, sadly is a requirement for some of my drivers, besides that,
here is a good place to declare some package overrides as well as permit unsafe
packages.

#+begin_src nix
nixpkgs.config = {
  allowUnfree = true;
};
#+end_src

* NORMAL USERS
Being part of the "wheel" group, means that the user has root privileges.

#+begin_src nix
users.users.jawz = {
  isNormalUser = true;
  extraGroups = [ "wheel" "networkmanager" "docker"
                  "scanner" "lp" "piracy" "kavita"
                  "render" "video"
                ];
  initialPassword = "password";
  openssh = {
    authorizedKeys.keys = [ "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIB5GaQM4N+yGAByibOFQOBVMV/6TjOfaGIP+NunMiK76 gpodeacero\cdreyes@100CDREYES"
                            "ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIKDXxfFRSgII4w/S1mrekPQdfXNifqRxwJa0wpQo72wB jawz@battlestation"
                          ];
  };
#+end_src

This section of the document categorizes and organizes all he packages that I
want installed, attempting to group them as dependencies of others when
necessary.

* USER PACKAGES
Begin the block to install user packages.
#+begin_src nix

hunspellDicts.it_IT
hunspellDicts.es_MX
hunspellDicts.en_CA

** CUSTOMIZATION PACKAGES
Themes and other customization, making my DE look the way I want is one of the
main draws of Linux for me.

#+begin_src nix

  fonts = [ "Agave" "CascadiaCode" "SourceCodePro"
            "Ubuntu" "FiraCode" "Iosevka" ];

** HOME-MANAGER SETTINGS

also allow for upgrades when rebuilding the system.

* SNAPRAID
It's a parity raid utility which creates a scheme similar to what UNRAID
offered, except not in real time, I schedule it to run every night, so it keeps
my files sync, while it is possible to use snapraid as a solution to keep a
historic backup of your files, I am more concerned with the whole disk recovery
in case of failure, as such a frequent sync fits my preferences.

* MISC SETTINGS
** ENABLE FONTCONFIG
If enabled, a Fontconfig configuration file will point to a set of default
fonts.  If you don't care about running X11 applications or any other program
that uses Fontconfig, you can turn this option off and prevent a dependency on
all those fonts.
=tip= once that Wayland is ready for deployment, I probably can remove this
setting.

#+begin_src nix
fonts.fontconfig.enable = true;
#+end_src

** NFS
#+begin_src nix
fileSystems = {
  "/export/disk1" = {
    device = "/mnt/disk1";
    options = ["bind"];
  };
  "/export/disk2" = {
    device = "/mnt/disk2";
    options = ["bind"];
  };
  "/export/seedbox" = {
    device = "/mnt/seedbox";
    options = ["bind"];
  };
  "/export/jawz" = {
    device = "/home/jawz";
    options = ["bind"];
  };
};
services.nfs = {
  server = {
    enable = true;
    exports = ''
      /export         192.168.1.64(rw,fsid=0,no_subtree_check)
      /export/disk1   192.168.1.64(rw,nohide,insecure,no_subtree_check)
      /export/disk2   192.168.1.64(rw,nohide,insecure,no_subtree_check)

    '';
  };

* FINAL SYSTEM CONFIGURATIONS
The first setting creates a copy the NixOS configuration file and link it from
the resulting system (/run/current-system/configuration.nix).  This is useful in
case you accidentally delete configuration.nix.

The version value determines the NixOS release from which the default settings for
stateful data, like file locations and database versions on your system.
It‘s perfectly fine and recommended to leave this value at the release version
of the first install of this system.

Lastly I configure in here Cachix repositories, which is a website that keeps a
cache of nixbuilds for easy quick deployments without having to compile
everything from scratch.

#+begin_src nix

  copySystemConfiguration = true;
  stateVersion = "${version}";
