Yum

view the documentation

The Yum is the application with command line interface. The main purpose of this application is to increase your cookings skills, which are represented as the level. All you need to do is to generate the recipe which you like, cook the food, eat it and review it using scale from 0 to 3. The better food you prepare, the more XP points you get. Increasing your XP points leads to increasing your level. And your level and XP points "unlock" for you more difficult recipes, which needs more time too cook.

The application uses the Yummly API to access the recipes of the food:

https://developer.yummly.com/

There is also used the Backendless REST as the storage of users data:

https://backendless.com/docs/rest/doc.html

Application uses Faraday adapter for executing the requests:

As the new user, you should registrate first with your email and password. After login, you start at level 0 and you are able to generate recipe. So let's cook!

Recipe may be generated only for the logged user, because its difficulty (maximal time for cooking) is computed from user's level. User is also able to set filter for searching in recipes (holiday recipes, diet, natioanl cuisines, ingredients, phrase,...) The command that provides recipe looks like this:

The user is able to view his last recipe

$ yum last

Expected scenario how to play this game is when user generaters the recipe, he cooks it after that. After all that cooking and eating, user is able to review his prepared food from 0 to 3 points. The reviews provides XP points to user. The user is able to review his last food only once. After that, his last food is deleted from the database.

$ yum review [0..3]
