Toggles to home manager modules

[alecandido]

Instead of using a list of toggles, like:
https://github.com/alecandido/nixpkgs/blob/b4d147a5d43712a8295c718bff96980eaaaedfee/systems/nixos/default.nix#L64
it would be more natural to have attributes, like:

{
  amenities = true;
  gnome = true;
  neovim = {
    lsp = true;
  };
  shell = "nu";
  thunderbird = true;
}

But even better, it would be to have an home-manager module where to write some configurations, and then use this high-level configs to enable a series of other configs (like right now it is happening for toggles).
https://nixos.org/manual/nixos/stable/index.html#sec-writing-modules

Using home-manager it should on every platform (including darwin), and the configurations could be added as an extra module in systems/.

• feature-gate neovim LSP servers

  • they are the biggest part of neovim (the other configs are light)

  • mostly at the level of Nix (avoid installing some packages)

  • propagate the information with an environment variable and catch it inside neovim
    as well (to disable the related configs and avoid failing)

    • in the first place let it fail
    • and then fix the failures with a test case
