jupylet's Issues

ipykernel_launcher error in vscode .ipynb cell

When I run the cells of 02-hello-jupylet.ipynb or of the other files from the examples,
in VSCode in .ipynb model,
on Win10 with Python 3.9,
and get error in cell of app = App(width=320, height=64):

usage: ipykernel_launcher [-h] [--window {pyglet,glfw}]
                          [--log_level {DEBUG,INFO,WARNING,ERROR}]

No error message if jupylet is used in a helper file

For example, suppose you have a file game.py with

from jupylet.label import Label as Label
from jupylet.app import App as App

app = App(width=320, height=64)

sitting next to a notebook in which you have

import game

hello = game.Label('hello, world', color='cyan', font_size=32, x=game.app.width, y=16)

@game.app.run_me_every(1/30)
def scroll(ct, dt):
    hello.x = hello.x - 1

    if hello.right < 0:
        hello.x = app.width
        
@game.app.event
def render(ct, dt):
    game.app.window.clear()
    hello.draw()
    
game.app.run()

This all runs fine. However, if syntax errors are introduced into scroll and render, no error message will appear.

App.run() does not automatically exit / quit

Hi, thanks for this amazing jupylet.
Installed and now trying the examples to understand how to use jupylet.
On Windows 10, using Python 3.6, I can't close all examples started from IDLE.
The same goes for all examples run on jupyter. When I close the jupyter's browser tabs, all jupylet examples are still running.
The only way to close the examples are thru Task Managers.

Is there any flag to set so that App.run() can automatically exit / quit when its window / display is closed ?
Or maybe "exit/quit event" that needs to be handled ?

Thank you

Multiple instances of App on the same notebook.

We can't run multiple Apps on the same notebook, right?

app = App(width=700, height=400)

app2 = App(width=700, height=400)

Running as stand-alone script on Windows

When run as a stand-alone script on Windows 10 (Python 3.7.9), example programs just die silently after the first jupylet import (e.g. from jupylet.sprite import Sprite in spaceship.py)

"SystemError: error return without exception set" when creating App

Hi,

I'm trying to run jupylet on Windows, with Python 3.9.1. After installing the libraries following the instructions on the docs, if I try to run any example that creates an App I am getting the error:

app = App()
---------------------------------------------------------------------------

Any idea what could be wrong?

Thank you!

Just a question about `sys.path.insert` in example notebooks

Why sys.path.insert(0, os.path.abspath('./..')) ?

Any hint for Jupylet to work in voila?

I want to show Jupylet works in Voila, or Streamlet, or PyWebIO,
but I can not see the canvas of Jupylet in Voila.
Any advice would be appreciated.

NameError: name 'sys' is not defined in env.py

Hello

I have just tried to integrate jupylet into my script. However I am getting the following error:
packages/jupylet/env.py:68: in has_display if 'pyglet' in sys.modules: E NameError: name 'sys' is not defined
when simply importing jupylet

It has been fixed for me by simply adding import sys in the head of that file locally.

Could you please fix that on the file?

Thanks!

Not working in Jupyter

When I try to test the game in Jupyter (notebook or lab) I can't play the game. When I try to press the up/down keys it responds by moving up or down a cell and when I try left/right it does nothing. It kinda seems like it might be displaying as a just image, I'm not sure.

Is there something I'm missing? Did I miss a step somewhere?

ENH: JupyterLite, WebGL

Method descriptions missing from Sounds Modules

I'm starting to get interested in exploring audio in Python and was excited to discover the capabilities of your Jupylet project.

But I've just realized that although the documentation is extensive, many of the classes in the Sound and related modules only have the attributes defined, not the methods. Is this an oversight, or because they are waiting updating for the latest code changes or just because you have not got around to documenting them yet?

I note that the code itself is quite well documented, so perhaps there is an issue with documentation not getting automatically generated from the docstrings correctly?

I know that I can find out basic information about the classes using the Python "help" function but this does give any explanation of the methods, just the bare bones of class definitions.

Anyway, you're the expert and I'm only guessing but if you would like help in this area, then I've got the time (if only limited expertise) so I could have a go at helping with documentation.

how to run an App() in a separate thread?

Hi,

I'd like to run an (headless) App in a separate thread.

I'd like to render some shaders, and use the framebuffer into another part of my application.

I tried this simple code:

#!/usr/bin/python3

import time
from jupylet.app import App

if __name__ == '__main__':

    def create_and_run_app():
        app = App(width=512, height=512, quality=100, fullscreen=False, mode="hidden")  #, log_level=logging.INFO)
        app.start()

    import _thread
    _thread.start_new_thread(create_and_run_app, ())

    time.sleep(10)

but I get this error:

Exception ignored in thread started by: <function create_and_run_app at 0x7f807b0060d0>
Traceback (most recent call last):
  File "p.py", line 9, in create_and_run_app
    app = App(width=512, height=512, quality=100, fullscreen=False, mode="hidden")  #, log_level=logging.INFO)
  File "/home/eric/tmp/jupylet/jupylet/app.py", line 184, in __init__
    self.window = window_cls(size=(width, height), **conf)
  File "/home/eric/tmp/jupylet/jupylet/event.py", line 81, in __init__
    self.init_mgl_context()
  File "/home/eric/tmp/jupylet/jupylet/event.py", line 103, in init_mgl_context
    self._ctx = moderngl.create_standalone_context(
  File "/home/eric/.local/lib/python3.9/site-packages/moderngl/context.py", line 1672, in create_standalone_context
    raise ValueError('Requested OpenGL version {}, got version {}'.format(
ValueError: Requested OpenGL version 330, got version 0

I also tried to use mode="auto" and app.run(), but I get:

Exception ignored in thread started by: <function create_and_run_app at 0x7f34e3fc30d0>
Traceback (most recent call last):
  File "p.py", line 10, in create_and_run_app
    app.run()
  File "/home/eric/tmp/jupylet/jupylet/app.py", line 333, in run
    loop = asyncio.get_event_loop()
  File "/usr/lib/python3.9/asyncio/events.py", line 642, in get_event_loop
    raise RuntimeError('There is no current event loop in thread %r.'
RuntimeError: There is no current event loop in thread 'Dummy-1'.

Is there a way to call a render iteration x times per second, or in a separate thread?

Thank you

Is there anything I can do about it?

Thank you

AttributeError: 'FreeTypeFont' object has no attribute 'getsize' with Pillow 10

right in example 02-hello-jupylet. This issue I found also in tensorflow, see this URL, where it was successfully resolved. I think, ipyleaflet can go this way, too (using old, deprecated getsize if it is available, or getbbox if it is not.

get realtime soundcard audio as input for shadertoy shaders

Hi,

I have tried some shadertoys examples.

It seems the audio input can be the 'output' from the sounds playing in jupylet, but is there a way to use realtime audio input from the soundcard?

Thank you

instantiating App() ovverrides argparse.parse_args()

For example, take this code:

#!/usr/bin/python3

import argparse
from jupylet.app import App
# app = App(width=512, height=512)

parser = argparse.ArgumentParser(description='bla')
args = parser.parse_args()

if I run:

$ ./p.py  --help

I get:

usage: p.py [-h]

bla

optional arguments:
  -h, --help  show this help message and exit

as expected.

But if I uncomment the line that instantiates app, I get:

$ ./p.py  --help

usage: p.py [-h] [--window {pyglet,glfw}] [--log_level {DEBUG,INFO,WARNING,ERROR}]

optional arguments:
  -h, --help            show this help message and exit
  --window {pyglet,glfw}
                        Windowing library to use.
  --log_level {DEBUG,INFO,WARNING,ERROR}
                        logging level.

So it makes it hard to import App outside of jupylet

Thanks
