Functions - LieutenantTeaTM/BubbleTea GitHub Wiki

Functions in BubbleTea are very strict. They have the following rules:

• A return type must be known, if no return type is desired it can be given a null return type
• The function must receive the return data

Syntax for functions goes as follows: fn IDENTIFIER ( args ) -> TYPE { BODY }

By default every BubbleTea program uses main() but you can user define functions. Functions cannot have an overlapping name with any external function.

Examples:

fn add(x: int, y: int) -> int {
    <- x + y;
}

fn say_hi() -> null {
    p!("Hi!");
}
