[1.12.2] Nested ConfigCategorys in arrays

Im new to Forge modding, Im currently trying to create a config that follows a structure like, or equivalent to this:

# Configuration file
materials [
  # some default comment that describes what these values do
  {
    S:ore=thermalfoundation:ore:0
    S:ingot=thermalfoundation:material:128
    S:dust=thermalfoundation:material:64
  } {
    S:ore=thermalfoundation:ore:1
    S:ingot=thermalfoundation:material:129
    S:dust=thermalfoundation:material:65
  } {
    S:ore=thermalfoundation:ore:2
    S:ingot=thermalfoundation:material:130
    S:dust=thermalfoundation:material:66
  }
  ## ... etc
]
general {
  B:enableDebug=true
  I:stuffidk=100
  ## etc etc
}

I want my mod to be standalone in sense of only having to have a forge installation.  Im quite reluctant to create custom scripts that parse and serialize raw text from files, and would like to keep using forge's provided configutation manager.  I want the amount of entry's in materials to be variable, with each having no name if possible.

Right now my code is fairly simple.  How would I go about achieving the above?

    public static Configuration config;
    private static String fileLocation = "config/"+OreUnify.MODID+".cfg";

    public static void init() {
        config = new Configuration(new File(fileLocation));
        //TODO default initialisation of config if empty

        try {
            config.load();
        } catch (Exception e) {
            System.out.println("Cannot load configuration file!");
        } finally {
            config.save();
        }

        //TODO read data and configure the mod
        ConfigCategory generalConfig = config.getCategory("general");
        someOtherThingIDK( generalConfig.get("enableDebug").getBoolean() );
        //anotherThingIteratingOverEntrys( ??? );
    }
