access super class in __init__

[ghost]

Allô,

I am working through an example for the Arcade game engine. It starts by extending the base game window class.

(defclass JetShooter [arcade.Window]
  (defn __init__ [self]
      (super.__init__ SCREEN_WIDTH SCREEN_HEIGHT SCREEN_TITLE)
          (setv self.enemies_list (arcade.SpriteList))
          (setv self.clouds_list (arcade.SpriteList))
          (setv self.all_sprites (arcade.SpriteList)))

Here is the error message from Hy; line 33 is the call to super.init.

  File "/home/claude/Programming/Python/JetAvoidsMissiles/main.hy", line 33, in __init__
    (super.__init__ SCREEN_WIDTH SCREEN_HEIGHT SCREEN_TITLE)
TypeError: descriptor '__init__' requires a 'super' object but received a 'int'

The Python code looks like this.

super().__init__(SCREEN_WIDTH, SCREEN_HEIGHT, SCREEN_TITLE)

I assume that the call super() returns a reference to the super object.

How does Hy express this Python idiom?

What is the correct way to initialize the super class?

Is there a document about translating Python to Hy?

Merci.

super().__init__(a, b, c) in Python is written (.__init__ (super) a b c) in Hy. (super.__init__ a b c) is different because you're not actually calling super, just taking the __init__ attribute of super itself.

Is there a document about translating Python to Hy?

There's the manual, and there's hy2py, but that's about it.

That makes sense. Merci.
