Get a kitty shortcut on Windows via WSL and WSLg for NixOS-WSL

Pre-requisite

• have WSLg installed
• use NixOS-WSL
• have bash as part of your system packages (just check /run/current-system/sw/bin/bash exists)

First, add kitty to your home-manager profile.

{ ... }:
{
  home-manager.users.<username> = {
    programs.kitty = {
      enable = true;
    };
  };
}

I had some weird font spacing issues, so I had to explicitely specify kitty to use the Hack font.

{ pkgs, ... }:
{
  fonts.fonts = with pkgs; [ hack-font ];
  
  home-manager.users.<username> = {
    fonts.fontconfig.enable = true;
    
    programs.kitty = {
      enable = true;
      font = {
        name = "Hack";
      };
    };
  };
}

After rebuild, create a shortcut on your Windows desktop.

Set its target to:

C:\Windows\System32\wsl.exe -d NixOS --cd ~ -e /run/current-system/sw/bin/bash -l kitty

If you have a high DPI, you might need to set .wslgconfig in your Windows user folder.
