Enumerations

Enumerations are a special kind of value type that represent a set of options from which one can be chosen.

Defining an Enumeration

The syntax to define an enumeration is:

enum ⟶ 🔘 type-identifier type-body
enum-value ⟶ 🆕▶️ emoji-id

For example:

🔘 ⏰ 🍇
  🆕▶️🥓
  🆕▶️🥞
  🆕▶️🥐
🍉

In this example, an enumeration that named ⏰ is defined which offers the values 🥓, 🥞 and 🥐.

Instantiating an Enumeration

Every enumeration automatically provides intializers for all its options, named after the option the instance will represent. Like any value type, enumerations are instantiated with 🆕:

🆕⏰▶️🥓❗

Enumerations cannot have custom initializers.

Methods

In the manner of any other value types, enumerations can have methods. The following examples shows an enumeration which provides a method that returns a textual description of the chosen value:

🔘 ⏰ 🍇
  🆕▶️🥓
  🆕▶️🥞
  🆕▶️🥐

  ❗️ 🔡 ➡️ 🔡🍇
    ↪️ 👇 🙌 🆕⏰▶️🥐❗️ 🍇
      ↩️ 🔤Croissant🔤
    🍉

    ↪️ 👇 🙌 🆕⏰▶️🥞❗️ 🍇
      ↩️ 🔤Pancakes🔤

    ↪️ 👇 🙌 🆕⏰▶️🥓❗️ 🍇
      ↩️ 🔤Bacon🔤
    🍉

    ↩️ 🔤🔤

Comparing Enums

🙌 can be used to compare whether two enum instances are equal:

🆕⏰▶️🥓❗️ ➡️ a
🆕⏰▶️🥓❗️ ➡️ b
↪️ a 🙌 b 🍇
