NixOs

This repo contains the nixos cfg for a few of my systems. It tends to be under heavy development as I am still in the "keep trying things" phase of my Nix learnings. This repo has moved from Gnome -> Pantheon -> Hyprland - > Gnome -> sway -> Hyprland -> Gnome. You see where I am going with this. It "feels" like Gnome is where I plan to stay for some time. I found the user experience to be good, and the OOTB configuration seems to work best. It allows me to stop messing around to a degree and get "back to work."

Which NIX is causing me to fail right now. "back to work." :)

Status

WIP, forever.

Code Flow

All code under the modules folder is imported via autoimport.nix. The modules folder code is set up with options, which are not used unless you enable the options in your system config.
Then archetype on the systems of choice

Example of a system cfg


# Shows using the archetype to enable a laptop and workstation
archetype = {
    laptop.enable = true;
    workstation.enable = true;
  };

    # enable my user of choice
    # Note - still some refactoring in some modules to adjust if you move from a "dustin" user to an additional user or different user
    users.dustin.enable = true;

    # enable the desktop I want to use on this system
    desktops.gnome.enable = true;

    # enable an app directly vs via an archetype or suite
    apps = {
        syncthing = {
            enable = true;
            host.evo = true;
        };

        # another exaple of direct module use
        desktopFile = {
        enable = true;
        reboot-firmware = true;
        seabird = true;
        beeper = true;
        monokle = true;
        cursor = true;
        spacedrive = true;
        };
    };

Home Manager Useage

I do use Home Manager, but not in the usual pattern.
I hated having two different locations to configure the same application if I had to (or wanted to) use base nix and home manager config.
So, I figured out how to have it all in one file. The modules/desktops/gnome/default.nix have an excellent example of this. In that file you will see:

# Above is traditional NixOS config

##### Home Manager Config options #####
    home-manager.users."${user-settings.user.username}" = {
# Everything in here is home-manager config

Secrets

My secrets just use git-crypt.
I know about SOPs, etc., but I wanted to be able to make a secret substitution in my code. You can see its use in modules/cli/git/default.nix, such as (I was rendering a config file for a tool):

[openai]
        api_base = "https://api.openai.com/v1"
        api_key = "${secrets.openai.api-key}"
        #model = "gpt-3.5-turbo-16k"
        retries = 2
        proxy = ""

Notes

Espanso

The Espanso service is funny. At times, the service will not start after an update. The fix "seems" to be:

upgrade the system.
Unregister the Espanso service with espanso service unregister
reboot, and let the services.espanso.enable = true; in my config, start the service.

Getting StartupWMClass For Web Apps

Getting the StartupWMClass is a pain in Wayland.

I enabled the Window Class extension in Gnome.
Then you can use a command to get the class of the window.
see the get_wm_class fish shell function in my fish module.

Steps for my setup

Note, I use brave, but this also works with chromium, or any browser that supports the same cli flags. You can set the desired brower in the module where you define the web app. See modules/apps/gcal-br/default.nix for an example.
Temporarily create a desktop shortcut for the site to wrap in brave
Copy the icons using the lib/cbb-webwrap/copy-icons.sh` script
Delete the app in brave
run brave --new-window --app="https://URL" and leave it running
Run get_wm_class in the terminal to get the StartupWMClass (save it somewhere)
I have a nix function for creating a web app in lib/cbb-webwrap/default.nixAn excellent example of how to use that nix function can be seen in modules/apps/gcal-br/default.nix
Icons will be funky until you log out and back in or reboot
Enable web app in the modules/archetype/workstation.nix file (or as appropriate in your setup)
rebuild
