Functions

Functions in Spicy look like this:

function make_string(x: uint8): string {
    return "%d" % x;
}

Functions without return value can either be written without return type, or returning void.

function nothing1() {}
function nothing2(): void {}

By default function arguments are passed as read-only references. To instead pass a mutable value declare the argument inout.

function barify(inout x: string) {
    x = "%s bar" % x;
}

global s = "foo";
assert s == "foo";
barify(s);
assert s == "foo bar";
