* ABOUT
Setting up the document.

#+begin_src nix
{ config, pkgs, ... }:
{ # 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, but for the time being,
the two ones I need are hardware and home-manager.

#+begin_src nix
imports = [
  ./hardware-configuration.nix
  <home-manager/nixos>
];
#+end_src

* BOOT
I am comfortable with the defaults which NixOS recommends for UEFI systems.

#+begin_src nix
boot.loader.systemd-boot.enable = true;
boot.loader.efi.canTouchEfiVariables = true;
#+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.

#+begin_src nix
networking.hostName = "workstation";
#+end_src

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.wireless.enable = true;
networking.networkmanager.enable = true;
#+end_src

** TIMEZONE

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

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

* DISPLAY MANAGER
At the time of writing this file, I require of X11, as the NVIDIA support for
Wayland isn't 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.

#+begin_src nix
services.xserver.enable = true;
#+end_src

As previously mentioned, the settings for useXkbConfig prompt issues.

#+begin_src nix
services.xserver.layout = "us";
# services.xserver.xkbOptions = {
#   "eurosign:e";
#   "caps:escape" # map caps to escape.
# };
#+end_src

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

#+begin_src nix
services.xserver.displayManager.gdm.enable = true;
services.xserver.desktopManager.gnome.enable = true;
environment.gnome.excludePackages = (with pkgs; [
  gnome-photos
  gnome-tour
  gnome-text-editor
  gnome-connections
  baobab
])
++ (with pkgs.gnome; [
  totem
  gedit
  gnome-music
  epiphany
  gnome-characters
  yelp
  simple-scan
  gnome-font-viewer
]);
#+end_src

* HARDWARE
** BLUETOOTH

#+begin_src nix
hardware.bluetooth.enable = true;
#+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;
security.rtkit.enable = true;
services.pipewire = {
  enable = true;
  alsa.enable = true;
  alsa.support32Bit = true;
  pulse.enable = true;
};
#+end_src

* SECURITY
Recently, I've gotten frustrated with OpenDoas, as such I've decided to
temporarily enable Sudo, but in the future, I plan to revert that decision.
** SUDO

#+begin_src nix
security.sudo = {
  enable = true;
  wheelNeedsPassword = false;
};
#+end_src

** OPENDOAS
It's mayor advantage over Sudo, is that is being a smaller package, being lessen known
means that there is less security risks associated with it, overall a less
bloated more secure package.  Which comes with the caveat that due to it's age,
there is little support for it.  Constantly having to resort to hack solutions
such as patches or symlinks.

#+begin_src nix
# security.sudo.enable = false;
# security.doas.enable = true;
# security.doas.extraRules = [{
#   users = [ "jawz" ];
#   keepEnv = true;
#   #persist = true;
#   noPass = true;
# }];
#+end_src

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

#+begin_src nix
users.users.jawz = {
  isNormalUser = true;
  extraGroups = [ "wheel" "networkmanager" ];
  initialPassword = "password";
  shell = pkgs.fish;
  packages = with pkgs; [ ];
};
#+end_src

* MISC SETTINGS
** ALLOW NON FREE packages

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

** 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

** WACOM
This setting could be a requirement for my tablet to properly work.  Even
though, my tablet is Huion, the Linux Wacom drivers cover most of the settings.

#+begin_src nix
# services.xserver.libinput.enable = true;
#+end_src

* HOME-MANAGER
** HOME-MANAGER SETTINGS
These make it so packages install to '/etc' rather than the user home directory,
also allow for upgrades when rebuilding the system.

#+begin_src nix
home-manager.useUserPackages = true;
home-manager.useGlobalPkgs = true;
#+end_src

** PACKAGES
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.

#+begin_src nix
home-manager.users.jawz = { config, pkgs, ... }:{
    imports = [ ./dotfiles/dconf.nix ];
    home.packages = with pkgs; [
#+end_src

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.

#+begin_src nix
system.copySystemConfiguration = true;
#+end_src

** NIX VERSION
This 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.
Before changing this value read the documentation for this option.

#+begin_src nix
system.stateVersion = "22.05";
#+end_src

** CLOSING :D
That super pesky closing bracket.

#+begin_src nix
}
#+end_src
