Background / 背景

I noticed that nix-config lacks any configuration for xdg.terminal-exec. As a result, when I right-click a file in some file managers (or elsewhere) and choose “Open With → nvim”, it may launch in a terminal other than my preferred one.
我发现 nix-config 缺少对 xdg.terminal-exec 的配置。这样当我在某些文件管理器或者其他地方右键选择“使用 nvim 打开”时，可能会在一个并非我期望的终端中启动。

Proposed Configuration / 建议的配置

I experimented with the NixOS xdg.terminal-exec option and found that it fixes this problem perfectly. Here’s the module I added under modules/nixos/desktop/xdg-terminal-exec.nix:
我试验了 NixOS 的 xdg.terminal-exec 选项，发现它能完美解决这个问题。以下是在 modules/nixos/desktop/xdg-terminal-exec.nix 中添加的 module：

{ lib, pkgs, ... }:

let
  my_terminal_desktop = [
    "foot.desktop"
    "Alacritty.desktop"
    "kitty.desktop"
    "com.mitchellh.ghostty.desktop"
  ];
in {
  environment.systemPackages = with pkgs; [
    # NOTE: These are installed in my home config
    # foot
    # Alacritty
    # kitty
    # ghostty
  ];

  xdg.terminal-exec = {
    enable  = true;
    package = pkgs.xdg-terminal-exec-mkhl;
    settings = {
      GNOME    = [ "com.raggesilver.BlackBox.desktop" "org.gnome.Terminal.desktop" ] ++ my_terminal_desktop;
      niri     = my_terminal-desktop;
      default  = my_terminal-desktop;
    };
  };
}

Questions / 报告中的疑问

File Organization
1.1. Is placing this file under modules/nixos/desktop/xdg-terminal-exec.nix right and maintainable, or might it become hard to manage as the number of desktop modules grows?
1.1 将该文件放在 modules/nixos/desktop/xdg-terminal-exec.nix 目录下是否合适并且可维护？随着 desktop 模块增多，这种方式是否会变得难以管理？
Conditional Terminal List
2.1. The current list is hard-coded (foot, Alacritty, kitty, ghostty). Is there a way to automatically include only those terminals that are actually installed (e.g., via a check in the module)?
2.1 现在的列表是写死的（foot、Alacritty、kitty、ghostty）。是否有办法让它只在确认这些终端已安装后才加入？
Separation Between NixOS Module and Home Packages
3.1. This config lives in a NixOS module (and the option comes from NixOS), but the terminals themselves are installed via home-manager. Is this separation problematic?
3.1 该配置写在 NixOS module 中（且选项来源于 NixOS），而终端却安装在 home-manager。这样分离是否有问题？

Possible Enhancement / 可行的改进思路

Wrap Terminal Collections
Define a top-level option such as desktop.terminals in the NixOS config; if desktop.terminals.kitty.enable = true then automatically install and config kitty , and add kitty.desktop to xdg.terminal-exec.settings.
封装终端集合
在顶层 NixOS 配置中定义选项，例如 desktop.terminals；若 desktop.terminals.kitty.enable = true，则自动安装、配置kitty，以及在 xdg.terminal-exec.settings 中加入 kitty.desktop。（但是可能需要在nixos和home两侧均定义，并且在output里面统一enable）
