nixos-config VS xmonad-contrib

I'm trying to setup NixOS with xmonad flake (something similar to this https://github.com/alternateved/nixos-config). When I try to rebuild my system, I get this error message (I got the same message when trying to build above mentioned config).

Not sure if this looks good, but I like how it works, therefore might be of interest: https://github.com/alternateved/nixos-config

I mainly use XMonad.Prompt module for session management (or whatever you would call that). I have session commands defined across those files and I use XMonad.Prompt.DirExec module to create a prompt which executes those scripts with [this line](https://github.com/alternateved/nixos-config/blob/f781c6006cd50e3e4becaa05572ccba5313f12df/config/xmonad/xmonad.hs#L279]

Feel free to peruse my config.

This is how I set my sway up. I am afraid this configuration might be a bit convoluted - I also use flakes and home-manager module.

Would you mind checking my sway configuration in nix and comparing it with yours?

I did not experience much tearing with my setup, you might check my configuration (picom part or intel one). Maybe it will be helpful anyhow.

I've set up my xmonad and xmobar as a cabal project. Here you could see xmonad and xmobar overrides. I build alternateved-xmonad binary from this directory and install it from here.

You could try switching to EZConfig and set your keybindings differently. I have that setup in my config, I find it much more readable. You would need to import XMonad.Util.EZConfig module.

It is much more complicated with haskellPackages, I am afraid. Even though there are flakes of xmonad and xmonad-contrib maintained by Ivan Malison, which makes it easier to add as my system's flake inputs, after I build NixOS with that configuration it just doesn't work.
