I'm trying to get a bit of a better grasp on the Nix language, rather than just as a vehicle for systems configuration.
As such, I have two configuration files that I'd like to take Nix sets/a list of sets to template out these files from.

I want to write a function that takes this:

{
  inputs = {
    "1:1:AT_Translated_Set_2_keyboard" = {
      xkb_layout = "gb";
      xkb_options = "ctrl:nocaps";
    };

    "1739:0:Synaptics_TM3381-002" = {
      pointer_accel = "0.7";
      tap = "enabled";
      dwt = "enabled";
      natural_scroll = "enabled";
    };
  };
}

And outputs this as a string:

input "1:1:AT_Translated_Set_2_keyboard" {
    xkb_layout gb
    xkb_options ctrl:nocaps
}

input "1739:0:Synaptics_TM3381-002" {
    pointer_accel 0.7
    tap enabled
    dwt enabled
    natural_scroll enabled
}

I'd like to write a function that takes this:

{
  outputs = [
    { eDP1 = {};}

    {
      "DP-1" = {
        position = "0,0";
        transform = "270";
      };

      "HDMI-A-2" = { position = "1440,470"; };
      "eDP-1" = { position = "1440,1910"; };
    }

    {
      "DP-3" = { position = "450,0"; };
      "DP-4" = { position = "0,1440"; };
      "eDP-1" = { position = "800,2880"; };
    }
  ];
}

And outputs this:

{
  output eDP-1
}
{
  output DP-1 position 0,0 transform 270
  output HDMI-A-2 position 1440,470
  output eDP-1 position 1440,1910
}
{
  output DP-3 position 450,0
  output DP-4 position 0,1440
  output eDP-1 position 800,2880
}

Any pointers to functions that do something similar that I can read as a point of reference,
or any help in general on how to do this would be greatly appreciated!
