You cannot. https://forum.omz-software.com/search/pyglet

Title says it all. I was trying to install it using stash. And it did work, but I had error about ctypes.macholib, which I fixed too, but now it says:

No Library found: GL

How can I install and run pyglet properly on Pythonista?

Looking at setup.py:

install_requires =
    requests[security]
    numpy
    scipy
    matplotlib
    pandas
    pillow
    pyglet
    pyopengl
    soundfile
    sounddevice
    python-bidi
    arabic_reshaper
    cffi
    future
    json_tricks
    pyosf
    xlrd
    openpyxl
    pyserial
    pyyaml
    gevent
    msgpack-numpy
    msgpack-python
    psutil
    tables
    pyzmq
    moviepy
    opencv-python
    python-gitlab
    gitpython
    astunparse
    esprima
    freetype-py
    # Platform-specific dependencies.
    imageio < 2.5; python_version < "3"
    imageio >= 2.5; python_version >= "3"
    imageio-ffmpeg; python_version >= "3"
    pyparallel; platform_system == "Linux"
    pyWinhook; platform_system == "Windows"
    pyqmix >= 2018.12.13; platform_system == "Windows"
    pyqt5; python_version >= "3"
    wxPython != 4.0.2, != 4.0.3; platform_system != "Linux"
    pypiwin32; platform_system == "Windows"
    pyobjc-core; platform_system == "Darwin"
    pyobjc-framework-Quartz; 

A good fraction of these are incompatible with pythonista. For instance scipy.

Thank you!

Is there a comparable simple ui module that works both in and out of pythonista? I had looked at pyglet but it requires pygame. I'd like to be able to work in pythonista but still have the program run elsewhere. I only need a very minimal UI... basically just a box to dump text in and a button or two to refresh it.

@ccc, Did you try this tool? If you need an offline tool to run shadertoy examples( all the great fractal examples,
3D examples), just a six-line code snippet (excluding fragment shader code) in Pythonista (as in mandelbrot.py) would do that.
May be you can add this to your Ten-lines-or-less repository. There does not seem to be a simple wrapper on pyglet or any other tool to do similar thing on windows PC or Mac. (The current code available on internet directly uses opengl apis and they are not very flexible.)
Simulating Pythonista scene behavior on pyglet was straightforward but getting fragement shader working needed a lot of experimentation.

Here is a utility to run pythonista scene based programs (including shader) in mac and PC using pyglet.
https://github.com/balachandrana/pythonista_pyglet_simulation
This is not 100 percent compatible but with slight changes (mainly for loading images) you can run most of the
pythonista scene based programs.The utility consists of three files, scene.py, shader.py and sound.py.
and the rest of the files are examples. You need to have python 2.7 and pyglet ("pip install pyglet"). There are no other dependencies.

The files mandelbrot.py and julia.py are fractal examples using fragment shader. The files slider.py and nqueen.py are simple games implemented using this utility. Rest of them are test examples. I have tried these examples on both mac and windows PC machines and they seem to work fine. Please let me know if there are any problems or questions.

I started this project to answer the question by @ccc whether his mandelbrot program can be run on Mac machine with
hardware graphic accelarators (shader support) from Python
(See the discussion in https://forum.omz-software.com/topic/3171/relative-performance-of-python2-vs-python3
from @ccc

Is there a similar way to use to the hardware of a Mac from Python?!? Your speedup is incredible!)

@omz, @ccc Thanks for your suggestions.

Pyglet is supposed to be good for opengl. There seems to be simple wrapper for
GLSL (see the url below), but I have not tried it.

@dgelessus - the recent addition of ctypes may allow us to inspect the ui classes now. I have been trying to write an object dumper/lister but it is slow going for me. Here is an example code of what is possible - dumping info about the core bluetooth classes and a few others.

from cocoapy.runtime import *

def list_methods(cls, type):
    count = c_uint()
    method_array = objc.class_copyMethodList(cls, byref(count))
    print '---', count.value, type, 'methods','---'
    names = []
    for i in range(count.value):
        method = c_void_p(method_array[i])
        sel = c_void_p(objc.method_getName(method))
        name = objc.sel_getName(sel)
        encoding = objc.method_getTypeEncoding(method)
        return_type = objc.method_copyReturnType(method)
        names.append((name, encoding, return_type))

    names.sort()
    for x, y, z in names: 
        print x, y

def list_variables(cls, type):
    count = c_uint()
    ivar_array = objc.class_copyIvarList(cls, byref(count))
    print '---', count.value, type, 'variables','---'
    names = []
    for i in range(count.value):
        ivar = c_void_p(ivar_array[i])
        name = objc.ivar_getName(ivar)
        encoding = objc.ivar_getTypeEncoding(ivar)
        names.append((name, encoding))

    names.sort()
    for x, y in names: 
        print x, y

CB_Classes = [

]

if __name__ == '__main__':
    for class_name in CB_Classes:
        cls = get_class(class_name)
        print '--------------------------'
        print 'class:', class_name
        list_methods(cls, 'instance')
        list_methods(get_object_class(cls), 'class')
        list_variables(cls, 'instance')
        print '--------------------------'

Uses a set of wrapper classes from cocoapy which is buried in pyglet, but the ByBee wrappers should also work.

I have not yet figured out how to look at any of the Pythonista App classes, only various frameworks that are linked in.

• Pyglet

Could you possibly implement the Pyglet module to Pythonista, so that I can make 3d animation games?
