module mode setup() issue, maybe?

[villares]

This used to work in module mode, didn't it? Or I'm getting it wrong and the setup disentanglement is just for imported mode?

py5.__version__ '0.8.2.dev0'

Update: it works in '0.8.0a2' it doesn't work in '0.8.1a1'.

from collections import deque  # a double-ended queue
import py5  # check out https://github.com/py5coding 

history = deque(maxlen=512)  # mouse dragged positions

def setup():   # py5 will call this once to set things up
    py5.size(600, 400)
    py5.no_stroke()
    py5.color_mode(py5.HSB)

def draw():   # py5 will call this in a loop
    py5.background(51)
    for i, (x, y) in enumerate(history):
        py5.fill(i / 2, 255, 255, 128)
        py5.circle(x, y, 8 + i / 16)
    if history:
        history.append(history.popleft())

def mouse_dragged():  # py5 will call this when you drag the mouse
    history.append((py5.mouse_x, py5.mouse_y))
    
def key_pressed():   # py5 will call this when a key is pressed
    history.clear()

py5.run_sketch()

Now:

Unable to obtain source code for setup(). Either make it obtainable or create a settings() function for calls to size(), fullscreen(), etc.
When not using the PDE, size() can only be used inside settings().
Remove the size() method from setup(), and add the following:
public void settings() {
  size(600, 400);
}

It's the comment after setup():

def setup(): # py5 will call this once to set things up

It will work if you remove the comment.

Last night I said I knew you'd find another bug for me to fix, and you did not disappoint! This is a stupid error in the split setup code that most likely has been in py5 for a long time. It shouldn't be difficult to fix. Thanks for finding this!

This is now fixed. Also fixed a similar problem caused by type hints:

def setup() -> None:
    py5.size(200, 200)

That's valid Python code that should work.

Just confirmed! 😄

@villares , you are very welcome!!!!
