Overall, it is a powerful and flexible terminal emulator for advanced users.

Installation

2.1 Using nix-shell

nix-shell -p kitty

2.2 System-Wide Installation on NixOS

environment.systemPackages = [
  pkgs.kitty
];

After modifying your configuration, apply the changes by running:

sudo nixos-rebuild switch

2.3 User-Specific Installation with Home Manager

home.packages = [ 
  pkgs.kitty 
];

After updating your configuration, apply the changes by running:

home-manager switch

Configuration

Note: Currently, configuring Kitty is possible only by using Home Manager.

3.1 Basic

programs.kitty = {
    enable = true;
};

3.2 Advanced

programs.kitty = lib.mkForce {
  enable = true;
  settings = {
    confirm_os_window_close = 0;
    dynamic_background_opacity = true;
    enable_audio_bell = false;
    mouse_hide_wait = "-1.0";
    window_padding_width = 10;
    background_opacity = "0.5";
    background_blur = 5;
    symbol_map = let
      mappings = [
        "U+23FB-U+23FE"
        "U+2B58"
        "U+E200-U+E2A9"
        "U+E0A0-U+E0A3"
        "U+E0B0-U+E0BF"
        "U+E0C0-U+E0C8"
        "U+E0CC-U+E0CF"
        "U+E0D0-U+E0D2"
        "U+E0D4"
        "U+E700-U+E7C5"
        "U+F000-U+F2E0"
        "U+2665"
        "U+26A1"
        "U+F400-U+F4A8"
        "U+F67C"
        "U+E000-U+E00A"
        "U+F300-U+F313"
        "U+E5FA-U+E62B"
      ];
    in
      (builtins.concatStringsSep "," mappings) + " Symbols Nerd Font";
  };
};

Tips and Tricks

4.1 Where to see a list of options?

The home manager options are defined in the following Home Manager Options Manual.

4.2 Can this be used with stylix?

Yes, it can. See the following configuration:

extraConfig = with config.stylix.base16Scheme; ''
  foreground #${base05}
  background #${base00}
  color0  #${base03}
  color1  #${base08}
  color2  #${base0B}
  color3  #${base09}
  color4  #${base0D}
  color5  #${base0E}
  color6  #${base0C}
  color7  #${base06}
  color8  #${base04}
  color9  #${base08}
  color10 #${base0B}
  color11 #${base0A}
  color12 #${base0C}
  color13 #${base0E}
  color14 #${base0C}
  color15 #${base07}
  color16 #${base00}
  color17 #${base0F}
  color18 #${base0B}
  color19 #${base09}
  color20 #${base0D}
  color21 #${base0E}
  color22 #${base0C}
  color23 #${base06}
  cursor  #${base07}
  cursor_text_color #${base00}
  selection_foreground #${base01}
  selection_background #${base0D}
  url_color #${base0C}
  active_border_color #${base04}
  inactive_border_color #${base00}
  bell_border_color #${base03}
  tab_bar_style fade
  tab_fade 1
  active_tab_foreground   #${base04}
  active_tab_background   #${base00}
  active_tab_font_style   bold
  inactive_tab_foreground #${base07}
  inactive_tab_background #${base08}
  inactive_tab_font_style bold
  tab_bar_background #${base00}
'';

Stylix can also do it automatically for you. You have to set:

stylix.targets.kitty.enable = true;

4.3 How to map kitty to a key?

It depends on the window manager that you are using. On Hyprland it's fairly easy:

bind = [
  "$mod, Q, exec, kitty"
];
