Variables

Val & Var

There are two types of variables: val and var. The latter is mutable and thus can be changes after assigning a value. The type of a variable will normally be inferred from the right hand expression but can be defined manually too.

EBNF Notation

variable = "var" | "val" , ( [ ":", name ] , "=" , expression | ":", name, [ "=" , expression ] ) ;
name = "a".."z" | "A".."Z", { "a".."z" | "A".."Z" | "0".."9" } ;

Simple Notation

• val foo
• var foo
• val: String foo
• var: String foo
• val foo = [expression] *
