cups VS nixos

And this disagrees with you: https://openprinting.github.io/cups/

Apple apparently acquired CUPS years after it was available as an OSS project. It fits given that I was using cups so long ago and never heard it as an apple project.

CUPS

In December 2019, Michael left Apple to start Lakeside Robotics. In September 2020 he teamed up with the OpenPrinting developers to fork Apple CUPS to continue its development. Today Apple CUPS is the version of CUPS that is provided with macOS® and iOS® while OpenPrinting CUPS is the version of CUPS being further developed by OpenPrinting for all operating systems.

This isn’t entirely true. There’s Apple CUPS (which is now focused on macOS/iOS) and OpenPrinting CUPS, which is used by Linux/other systems.

Not for long.

Printer support on Linux is actually pretty great thanks to CUPS. I'd expect most of not all mainstream brands to work.

Has that improved/changed since IPP Everywhere became a thing & CUPS moved to that?

I don't know. Have been using colorbuddy for ages now and it has always done exactly what I want. I don't need the "instant reaload" that lush advertices, doing :source on the colorscheme file, does the same for me to preview changes instantly. This is my theme, in case you need something to start with: - https://github.com/pinpox/nixos/blob/main/home-manager/modules/nvim/lua/config/pinpox-colors.lua

I use this to serve a directory temporarily.

I can't remember why I put that workaround in there, might not be needed any more. The above config is part of my dotfiles, I use my Bose blueutooth headphones by connecting them via the blueman-applet if the don't pair automatically

Here is an example from my config : I'm using an external flake called "matrix-hook", which is a little tool I wrote and have put in a separate flake. It get's included here. I am then passing self to each of the nixosConfigurations here, this allows me to import the module from the external flake in the configuration.nix of the host where I want to use it.

Yep, I have two different modules with defaults for server and for desktop. Host-specific settings are set in the according /machines//configuration.nix file. Most stuff is modularized into modules that can be reuesed and enabled at will.

Yep, I'm using the toJSON function already. The problem I had, was that not all applications use JSON as configuration format. Also the nix code gets very long, if you have to write the whole template as a string, which I find quite unreadable. Mustache is a pretty simple frequently used templating language, here is an example template that get's rendered by the nix code above.

My system uses a uniform colorscheme defined here. Configs for all applications I use read that and use the same colors. The wallpapers are randomly generated by a tool I wrote, it also automatically matches the colorscheme. Icons and symbols are colored the same way for awesomeWM.

In case you are interested I use this and this to generate colorschemes, awesome config and a matching wallpaper

Check out wezterm it has replaced tmux for me. Very active development, fast and just the right amount of features for my taste. It is configured in Lua, so if you are doing that for neovim already, it's another plus. I use it in combination with awesomeWM. My (not very special) config is here if you need something to start with.
