RuntimeError involving freeze_support()

Hi,

Using Python 3.9.4 I try to create a notification with the following line:

client.create_notification("Title TEST", "Subtitle TEST", "Text TEST")

Instead of the notification popping up, the following error is raised:

File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/multiprocessing/spawn.py", line 134, in _check_not_importing_main
    raise RuntimeError('''
RuntimeError: 
        An attempt has been made to start a new process before the
        current process has finished its bootstrapping phase.

        This probably means that you are not using fork to start your
        child processes and you have forgotten to use the proper idiom
        in the main module:

            if __name__ == '__main__':
                freeze_support()
                ...

        The "freeze_support()" line can be omitted if the program
        is not going to be frozen to produce an executable.

Somebody knows what's going on? Would appreciate the help, thanks! 🙏🏻

AttributeError: 'NoneType' object has no attribute 'setDelegate_'

Python 3.11.3, "client.create_notification" returns the following error:

Got the following error trying to create notification:

Add optional User Notification support

I can try and help implement support for the supported User Notification API. One issue is that you have to fallback to the old API when your python install isn't codesigned (for example python from homebrew)

You can check if it is supported pretty easily with this

from UserNotifications import UNUserNotificationCenter
def auth_callback(granted, err):
    print("Granted: ", granted)
    print("Error in authorization request: ", err)

c = UNUserNotificationCenter.currentNotificationCenter()
c.requestAuthorizationWithOptions_completionHandler_(0b111111,auth_callback

Python's icon

Hi Jorricks!

I want to ask you if you've looked into changing the default Python icon that pops up in the notification on the left and, if you have, could you share how to do it.

Thanks for the code!

Link in documentation with instructions on enabling notifications points to a wrong location

Hello,

Link in documentation with instructions on enabling notifications points to a wrong location.

Issue is here:
https://jorricks.github.io/macos-notifications/faq/
you first need to allow Python to create notifications. Instructions on this can be found [here]

And it points to a wrong location:
https://www.jetbrains.com/idea/guide/tips/enable-soft-wrap/#:~:text=You%20can%20enable%20soft%20wrap,more%20file%20types%20by%20default.).

Thanks

Library not working in frozen application (e.g. with PyInstaller)

I'm trying to build a CLI/Terminal app (frozen with PyInstaller), and it seems that the macos-notifications library starts a new process that calls my CLI again, but with unexpected parameters. Is there any way to work around this problem?

MacOSNotification is overriding existing Objective-C class

Hi,
I get this whenever I try to create the second notification. The first one goes out okay and any further call will result in this error. The first notification is still visible, so no one has closed it yet. I suppose that's the problem and it's trying to override the notification that is currently active and visible instead of creating a new one, like slack or any other chat normally does.

I'm using python 3.9 and Mac OS Big Sur.

python3.9/site-packages/mac_notifications/notification_sender.py", line 29, in create_notification
    class MacOSNotification(NSObject):
objc.error: MacOSNotification is overriding existing Objective-C class

mac_notifications-utilizing process never exits

Here's a test program that demonstrates the problem:

#!/usr/bin/env python3

import sys
import time

from mac_notifications import client


def noop(*args, **kwargs):
    """No operation: do nothing."""
    pass


class Callback:
    def __init__(self):
        self.called_back = False

    def callback(self, *args, **kwargs):
        print(f'args: {args}')
        print(f'kwargs: {kwargs}')
        self.called_back = True


if __name__ == '__main__':
    cb = Callback()
    client.create_notification(
        title="title",
        subtitle="subtitle",
        icon=None,
        action_button_str="Acknowledge",
        action_callback=cb.callback,
    )
    while not cb.called_back:
        print('waiting...')
        sys.stdout.flush()
        time.sleep(1)
    print('hello!')

It never exits. It does the print('hello!') fine, but the process just keeps running.

What do I need to do to get the process to exit normally?

Thanks!

Examples with callbacks always timeout

When a reply is sent:

The Notification still timeout in the example. Is this how it should work? My expectation was that we either get a reply and quit or get no reply and timeout.

Installation conflicts with latest version of PyObjC

macos-notifications has a dependency pyobjc-core==8.5.
On my machine with the current pyobjc-core (9.0.1), this causes python3 -m pip install macos-notifications to fail.

Would it be possible to upgrade the dependency?

Thanks!

Possible to send notifications to other users and/or send from daemon process?

I tried to call create_notification() from a daemon process that runs as root and it failed with builtins.ValueError: bad value(s) in fds_to_keep. That sort of makes sense given that root isn't a regular user. While I'm not sure this is even possible I was hoping to find a parameter for the userInfo argument that the objective-c NSUserNotification constructor takes and didn't see anything. Would it be possible to implement such a thing? I could maybe help with a pull request.

Icon is blocked?

When running your examples the icon is somehow "blocked"?

Is this known?

macos-notifications fails to install on CPython 3.11

macos-notifications itself may be OK. But it's probably insisting on having a version of pyobjc-core that is too old for 3.11. Maybe a setup.py problem?

pyobjc-core installs fine on 3.11 if you don't constrain what version it gets - that is, if you install it by itself. But installing macos-notifications tries to install pyobjc-core, and that fails.

One program, two notifications: one notification seems to dismiss the other

I don't really know much about MacOS' notifications, but should one notification that's already up, be knocked down by a second notification?

EG, in the snippet below, I've got 2 notifications in the one program, each notification having 1 callback - but I can't seem to find where to acknowledge "the other one".

Should I block until the first is acknowledged before submitting the second? Is there a way to make the notifications "pile up"?

#!/usr/bin/env python3

import sys
import time

from mac_notifications import client


class Callback:
    def __init__(self):
        self.called_back = False

    def callback(self):
        self.called_back = True

    def __str__(self):
        if self.called_back:
            return 'callback called'
        else:
            return 'callback not called'

    __repr__ = __str__


if __name__ == '__main__':
    popup_list = []
    for i in range(2):
        cb = Callback()
        popup_list.append(cb)
        client.create_notification(
            title="title {}".format(i),
            subtitle="subtitle",
            icon=None,
            action_button_str="Acknowledge",
            action_callback=cb.callback,
        )
    while not all(p.called_back for p in popup_list):
        print('waiting...:', popup_list)
        sys.stdout.flush()
        time.sleep(1)
    client.stop_listening_for_callbacks()
    print('hello!')

Thanks!

There is no API to delete notifications

There is no way to close a notification.

For example, there is no need to keep showing "unread messages" notification after messages are read, but the library can't stop showing it.

The library amends process logging

Process-wide changes are not something that expected from a library.

macos-notifications/src/mac_notifications/client.py

Line 15 in 6f0741d

logging.basicConfig(level=logging.INFO)

macos-notifications 0.1.5 does not give a notification on python 3.10

I'm using homebrew CPython 3.10, macos-notifications 0.1.5 and MacOS 12.6 on an Intel Mac.

This script is what I'm using to test macos-notifications:

#!/usr/bin/env python3

from time import sleep

from mac_notifications import client

if __name__ == '__main__':
    client.create_notification(
        title="title",
        subtitle="subtitle",
        icon=None,
    )
    sleep(60)

I'm running it with:
/usr/local/bin/python3.10 tst

But no notification comes up.

Any suggestions?

Thanks!

Python3.7 install of macos-notifications does not show a notification

  from mac_notifications import client

  client.create_notification(
    title = 'New To-Do',
    text = 'Test', # todo['body'],
  )

causes an error for me:

Missing from the documentation? How to create a persistent notification

I have a program I want to use mac_notifications in.

I need the notification to stay visible until clicked though - timing out after a handful of seconds doesn't work well for this application.

I don't see anything about this in the documentation. The closest seems to be:
:param delay: Delay before showing the message.

Am I missing something?

Thanks!
