Enumerations: Difference between revisions

 

The only way to give such a variable a value without setting it explicitly is to add one to the previous such variable which (in effect) is what a C-style enum does. If you declare a variable in Wren without giving it a value, then it is set to the special value ''null'' which is no help here.

var ORANGE = 2

var PEAR = 3

var Fruit = Enum.create("Fruit", ["apple", "orange", "pear", "cherry", "banana", "grape"], 1)
