Writing a donut recipe in TableGen

With the knowledge from previous sections, it's time to write our own donut recipe! We'll proceed as follows:

1. The first file to create is Kitchen.td. It defines the environment for cooking, including measuring units, equipment, and procedures, to name but a few aspects. We are going to start with the measuring units, as follows:

   class Unit {
     string Text;
     bit Imperial;
   }

   Here, the Text field is the textual format showing on the recipe, and Imperial is just a Boolean flag marking whether this unit is imperial or metric. Each weight or volume unit will be a record inheriting from this class—have a look at the following code snippet for an example of this:

   def gram_unit : Unit {
     let Imperial = false;
     let Text = "g";
   }
   def tbsp_unit : Unit {
     let Imperial = true;
     let Text = "tbsp";
   }
