for Cooking Recipes and Nutrition Analysis

• Jia Chen Language Architect
• Jeff Hull Tester and Validator
• Kuang Shen System Integrator
• Yiping Xu Tools Guru

The Purpose of TROC

• Healthy Diet ? Lifestyle
• various diet services found on/offline
• which theory do I follow??
• how to know the healthiness of my own diet
• hard for amateur to calculate the nutrition
  facts

4
The Purpose of TROC

• Then comes TROC!
• 1 create your own recipes for daily diet
• 2 have nutrition facts auto-calculated
• 3 adjust recipe to healthize diet
• 4 recalculate, if still unsatisfied GOTO line
  3
• 5 cook
• 6 inject food

Design Principles

• Syntax - Close to recipe convention
• - Less ambiguous
• - Smooth learning curve

20-Minute Beef Stew 3 pounds boneless beef, cut
into cubes 1/3 cup flour 1 ½ cups wine 3
tablespoons oliveoil 1 onion, chopped 2 carrots,
cut into pieces 1 pound potatoes, cut into
pieces Salt and ground pepper Coat beef with
flour, salt and pepper Warm oliveoil with
pressure cooker for 3 minutes Add
wine,beef,onion,potato and carrot into the
cooker Cook on high for 20 minutes Serve.

Design Principles

• Semantics- Strongly Typed
• e.g. Rule Cook Ingredient with Cookware
• Cook Beef with PressureCooker
• Cook Beef with MixingBowl
• - Static Typing
• - Object inheritance
• - Integrated Metric System
• e.g. olvOil 3 teaspoon OliveOil
• equivalent to 0.5 oz OliveOil
• Translation done at compile time

7
Runtime

• Runtime Routine Calls
• - Program written in TROC is translated into
  java code which call functions in TROC
  run-time API
• Nutrition Facts Calculation
• - Embedded in the TROC API functions, based on
  the ingredients, tools and operations
  involved
• - Formula based on the online authentic
  nutrient database created and maintained
  by Nutrition.gov

8
Execution Output

• Using external library to output result from
  Microsoft Excel

Runtime Environment

• Troc Type Definition
• Cook Operation API

Troc Type Hierarchy
Ingredient

CookWare

13
Inheritance

• If there is something that is not one of the food
  type we already have,

Inheritance!
Grammar Mushroom is a kind of Vegetable with
white color, 10 Juiciness... M1 20 g
Mushroom
14
Cook Operation API

• Cut (IngredientType beingCutObject, ToolType
  toolID, int Weight,)
• Cook(IngredientType beingCookedObject,
• ContainerTyper , int Weight)
• Other cook operations that we support
• Place, Crush, Marinate, Coat,

15
Runtime API Functionality

• Calculate the nutrition
• Based on the formula
• Render the chart

Runtime Output
17
Test Plan

• Smoke Test
• Begin by testing the high level features
• Unit Testing
• Create test cases for every function in API
• black-box approach
• compare the actual results with expected results
• Regression Testing
• Maintained a test file, where for every new
  grammar construct added, we will run the test
  file to maintain program consistency
• Tested for
• Logical errors/inconsistencies
• Syntax inconsistencies
• Overall success of instructions

18
Conclusions

• What We Learned
• Aside from some healthy recipes
• Gained Valuable Group work experience
• How to cope when a team member quits
• The ins and outs of designing a Language
• How to limit the scope and complexity of your
  project

19
Why Use our Language?

• The benefits of healthy eating are too numerous
  to name. Our language can help you cook and eat
  healthier.
