Enumerations

Spice supports simple enumerations. These constructs are syntactic sugar over int constants.

Usage¶

Enumerations in Spice work like this:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

type Fruit enum {
    APPLE,
    BANANA,
    MANGO,
    ORANGE
}

f<int> main() {
    printf("Test: %d", Fruit::MANGO);
}

They can be defined only in the global scope. Spice will assign the unsigned integer values 0 to 3 to the items automatically.

Enum items can have values assigned to them. Here is an example:

1
2
3
4
5
6

type Vegetable enum {
    CUCUMBER = 5,
    TOMATO,
    CARROT = 2,
    POTATO
}

For items without an explicit value, Spice assigns the lowest non-negative integer not already taken by any other item in the enum. Here CUCUMBER = 5 and CARROT = 2 are already claimed, so the compiler assigns TOMATO = 0 and POTATO = 1.
