packaging for macOs - configparser error

[Joerg B]

Hi there I’m having a question regarding packaging for macOS. I was following the instructions for using pyinstaller. 

The app isn’t starting. It throws an error saying that there is a key error with configparser. 

I guess that means that configparser can’t find the .ini files. I also tried to put all the .py and .ini files in the root directory.

Does anyone have an idea how to sort that out?

Thanks

Joerg

I was able to narrow it down a bit. If I activate a virtual env and start main.py, it's only working if I cd in the directory where main.py is before. 
Starting it from an other directory like python ~/folder/main.py I'm getting the same error. 
So I'm pretty certain it's not a kivy related question.

Here are a few macos specific fixes.

 

The problem you are having is you need to set the location of the config file. Add the code below to your App class. This will change the location of the config file on MacOS.  You can change this to a different location if you prefer.

    def get_application_config(self, defaultpath='%(appdir)s/%(appname)s.ini'):

        if platform == 'macosx':  # mac will not write into app folder

            s = '~/.%(appname)s.ini'

        else:

            s = defaultpath

        return super().get_application_config(defaultpath=s)

 

Here are a few other Mac specific fixes…

The Mac uses higher resolutions icons that Windows.  I create a file called configstartup.py.  This file is imported into main.py before kivy.app.App is imported. I also use this to preserve the Window size between runs.   This repository shows how to maintain Window size: https://github.com/ElliotGarbus/KivyWindowSize

 

 

from configparser import ConfigParser

from kivy.config import Config

from kivy.utils import platform

"""

configstartup.py is used to set graphics 

This code must be at the top of the 'main' executable file.  

Config.set('graphics'...) are used to set the size of the main window.

Win10 requires the windows size to be set prior to App being loaded, to draw smoothly

"""

# Default window size and position, also used to set minimum window size

window_width = 1000

window_height = 650

window_top = 50

window_left = 100

if platform != 'macosx':

    import os

    ini_file = os.path.join(os.getcwd(), 'your_configfile.ini')

    # Use Python lib configparser to read .ini file prior to app startup

    parser = ConfigParser()

    found = parser.read(ini_file)  # created in main.py: build_config()

    if found:

        Config.set('graphics', 'width', parser['Window']['width'])

        Config.set('graphics', 'height', parser['Window']['height'])

        Config.set('graphics', 'position', 'custom')

        Config.set('graphics', 'top', parser['Window']['top'])  # find top and left

        Config.set('graphics', 'left', parser['Window']['left'])

    else:

        Config.set('graphics', 'width', window_width)  # default value match default values in main.py: build_config, on_start

        Config.set('graphics', 'height', window_height)

        Config.set('graphics', 'position', 'custom')

        Config.set('graphics', 'top', window_top)

        Config.set('graphics', 'left', window_left)

if platform == 'macosx':

    Config.set('kivy', 'window_icon','Images/surgeon_app_logo_512.png')

else:

    Config.set('kivy', 'window_icon','Images/surgeon_app_logo_64.png')  # Windows uses a small png

Config.set('kivy', 'exit_on_escape', 0)

Config.set('input', 'mouse', 'mouse,disable_multitouch')

#Config.set('kivy', 'log_level', 'error')

 

 

For reference here is my mac specfile:

app_name = 'MyApp Name Here'

mac_icon = '../Images/logo_512.icns'
