@cvp, do I understand correctly that the need to relaunch Pythonista depends on how your script is launched?

ccc

I suspect that the script is the impressive https://github.com/cvpe/Pythonista-scripts/blob/master/contacts on map.py and that memory is being allocated but not being released.

cvp

@mikael no, no. It depends on which script. Sometimes, when I launch some big scripts using a lot of memory, as @ccc said, even if I run it in Pythonista, I can't rerun it without removing Pythonista. But, it is sometimes, not always.

cvp

@ccc No, no. The script showing my contacts on a map is not a big script and I don't have 1200 contacts (happily). It is a very big script (at least for me) of 7500 lines written for a friend who is "radio amateur" and showing the 1200 contacts he has realized with other people in the world. Each pin has an associated DetailCalloutAccessoryView with address, flag and other informations.
And, seeing the two rows of menu buttons, you can imagine that the program offers a lot of functionalities

@cvp, oh my goodness, that looks cool!

@mikael yes sir, and even 3D FlyOver. And all that thanks to Pythonista and some marvelous modules like Gestures, WKWebView of a guy called @mikael 😂

Hi,

thanks a lot for all the answer. But this doesn't solve my problem. So for now i made a simple example for everyone which will show my problem. I created a python script like this:

import ui
import os 

def close(sender):
    v.close()
    os.abort()
    
v = ui.load_view()
v.present('sheet')

and a pyui:

[
  {
    "nodes" : [
      {
        "nodes" : [

        ],
        "frame" : "{{95, 162}, {80, 55}}",
        "class" : "Button",
        "attributes" : {
          "action" : "close",
          "frame" : "{{95, 217}, {80, 32}}",
          "title" : "Button",
          "uuid" : "B05F9F96-41D2-41C1-B4E1-C27F68D5CD4A",
          "class" : "Button",
          "name" : "button1",
          "font_size" : 15
        },
        "selected" : true
      }
    ],
    "frame" : "{{0, 0}, {270, 466}}",
    "class" : "View",
    "attributes" : {
      "enabled" : true,
      "background_color" : "RGBA(1.000000,1.000000,1.000000,1.000000)",
      "tint_color" : "RGBA(0.000000,0.478000,1.000000,1.000000)",
      "border_color" : "RGBA(0.000000,0.000000,0.000000,1.000000)",
      "flex" : ""
    },
    "selected" : false
  }
]

With this script and UI i just add a Button on the Home screen like it is described in Pythonista.

Then i close all app on my iphone. I press the button and the App is opening twice. I press the Button in the UI and it closes. I see the normal Iphone homescren. If i now press the Home screen Button of the App (the shortcut), i only see a screen from Pythonista with a complete green background. I have to close manually from the IOS all pythonista screen and after this i can normally start the shortcut of the script again. So how can help me with this.

Thanks a lot.

@kami perhaps the same as known issue here

mikael

@kami, just to rule out potential issues, can you confirm that you tried launching your script via a home screen icon that you created with the Apple Shortcuts app?

I used this simple script, called test-launch.py:

import ui, os

class SuperClose(ui.View):
    
    def will_close(self):
        os.abort()
        
v = SuperClose(background_color='red')

v.present()

And this URL in the Shorcuts app:

pythonista3://test-launch?action=run

And the script is launched only once and Pythonista goes away when I close the view.

cvp

@mikael I think he uses omz' script for creating an icon on home screen (here) and in this case, tapping the icon starts twice the app.

HI, i will try to create an Apple Shortcut. But can someone please tell me how to write the path if the files are stored in the icloud?

Thanks a lot.

cvp

@kami see the Pythonista doc, The Pythonista URL Scheme

Add this at end of your url scheme

 ?root=icloud

Ex: pythonista3://my_folder/my_script?action=run&root=icloud&argv=argument

Hi, thanks a lot. Now with the Apple Shortcut everything works fine.
