GATE

⚠ Warning! GATE is currently undergoing heavy development and is not yet production-ready! An engine integration will soon follow.

GATE is a GDScript superset for the Godot Engine that adds extra features while compiling down to native GDScript.

Usage

Download the latest build for your OS from here and use it as follows:

# --input, -i
#    Path to the input `.gate` file/directory.
#    Note: Only `.gate` files are read.
#
# --output, -i
#    Path to the output directory.
#    Note: The output directory respects the input layout.

./gate --input ./path/to/myFile.gate --output ./output

Features

Dynamic Variable Decorator $$

The $$ decorator automates signal, setter, getter, and connection creation.

Example

class_name Test extends Label

$$count = 0

func _ready() -> void:
    count += 1

func count_changed(value: int) -> void:
  text = "Count is %s" % value

Optional Operator ?.

The ?. (optional) operator allows you to check for null in a chain of properties. Note: This currently only works with variable!

Example

func _ready() -> void:
    # In this case `text` is either `null` or the
    # expected value of `myProp`
    var text = $MyNode?.myObject?.myProp

Upcoming features

• Loop ranges 2..15
  • for i in 2..15:
• Spread operator ...
  • var arr = [0, 1, 2]
var numbers = [...arr, 3, 4, 5]
• Rest operator ...
  • myFunction(a, b, c, d, e)
func myFunction(first, second, ...rest)
• Destructuring [_, _]
  • var [parm1, param2] = myFunction()
• Inline templates
  • var x = `${player1} killed ${player2}`
• Optional chaining ?.
  • var x = $node.?thing.?deeper1.?deeper2
