Example of packaging app using py2app

[cztomczak]

See https://py2app.readthedocs.io/en/latest/

Example setup.py file:

import os
from setuptools import setup

# If not set possibly could result in a blank window issue
os.environ['MACOSX_DEPLOYMENT_TARGET'] = "10.9"

APP_VERSION = '1.0.0'
OPTIONS = {
    'packages' : ['cefpython3', 'objc', 'json', 'urllib'],
    # 'iconfile' : 'appicon.icns',
    'plist' : {
        'CFBundleIdentifier' : 'hello.world',
        'CFBundleShortVersionString' : APP_VERSION,
        'CFBundleVersion' : APP_VERSION,
    }
}

setup(
    name="Hello World",
    app=["hello_world.py"],
    data_files=[],
    options={'py2app': OPTIONS},
    setup_requires=['py2app']
)

CEF Python expects a certain directory structure and if py2app uses a different structure then you have to set these paths manually, for example with such code:

options = {
    "framework_dir_path": os.path.abspath("lib/python3.7/cefpython3/Chromium Embedded Framework.framework"),
    "browser_subprocess_path": os.path.abspath("lib/python3.7/cefpython3/subprocess")
}
cef.Initialize(settings=options)
