Functions

You can make a simple function block with brace brackets.

{ print "Hello world!" }

{
    print "Hello world!"
    print "DreamTode is the future!"
}

When a function is expected, you can leave off the brackets.

print "Hello world!"

Parameters

The => operator gives a function some parameters.

[a, b] => { return a + b }

You can leave off the brace brackets and return for single-line functions.

[a, b] => a + b

The -> operator does the same thing, but the function won't return anything when called.

[name] -> print "Hello {name}"

Calling

To call a function... put an array of arguments after it.

([a, b] => a + b)(3, 2)

If a function takes no arguments, you can call it with an empty array.

{ print "Hello world!" }()

Alternatively, you can use the : operator to place the first argument in front of the block.

(3):([a, b] => a + b)(2)
