anyrun-nixos-options

An anyrun plugin that lets you search NixOS options.

how 2 build?

nix build ... or cargo build optionally :)

Configuration

This plugin requires a config in your anyrun config directory called nixos_options.ron. The file looks like this:

Config(
  options: {":prefix": ["/path/to/options.json"] }, // You can obtain NixOS's options.json using config.system.build.manual.optionsJSON
  min_score: 0, // Optional, the minimum score of entries to show. Set it to a larger value on slow machines. Default: 0
  nixpkgs_url: "https://github.com/NixOS/nixpkgs/blob/nixos-unstable", // Optional, URL to Nixpkgs tree. Set it to use the same branch as you're using. Defaults to the unstable url.
  max_entries: Some(10) // max_entries specific to this plugin. Set to None to disable
)

Important: Make sure to set a max_entries either in your anyrun config, or in this plugin's config. Without that, the plugin will be VERY slow, since there exist over 16 thousand options to search through at the time of writing this. I have set mine to 10, since even that value is enough for it to go off-screen, so you shouldn't lose any data.

Using this with NixOS?

Under flakes, the following instructions will apply:

1. Use the anyrun home-manager module
2. Add the plugin to your anyrun plugins list

programs.anyrun.config = {
    # ...
    plugins = [
        inputs.anyrun-nixos-options.packages.${pkgs.system}.default
        # other plugins that you might have
    ];
    # ...
};

3. Create a config file for it:

#                  ↓ make sure osConfig is in the argument set
{inputs, pkgs, osConfig,  ...}: {
    programs.anyrun.extraConfigFiles."nixos-options.ron".text = let
        #               ↓ home-manager refers to the nixos configuration as osConfig
        nixos-options = osConfig.system.build.manual.optionsJSON + "/share/doc/nixos/options.json";
        # merge your options
        options = builtins.toJSON {
          ":nix" = [nixos-options];
        };
        # or alternatively if you wish to read any other documentation options, such as home-manager
        # get the docs-json package from the home-manager flake
        # hm-options = inputs.home-manager.packages.${pkgs.system}.docs-json + "/share/doc/home-manager/options.json";
        # options = builtins.toJSON {
        #   ":nix" = [nixos-options];
        #   ":hm" = [hm-options];
        #   ":something-else" = [some-other-option];
        #   ":nall" = [nixos-options hm-options some-other-option];
        # };

    in ''
        Config(
            // add your option paths
            options: ${options},
         )
    '';
}

4. You are done. Rebuild your system and run anyrun as usual. :nix should bring up your NixOS (and any other configured) options

Without flakes, inputs... generally should be changed to or depending on your usage.
