    Sure is. You just need to know the file path of the external app. Create a script called test.py with the following content in Working Copy. Open that repo in Pythonista. Run the script.

    import os
    cwd = os.getcwd()
    with open(f"{cwd}/test.py") as f:

    This prints the full path to the directory of test.py, then reads and prints the contents of that file. Reading other files from the same directory is trivial. Note that this only works for files in folders which you have already opened in Pythonista (Pythonista doesn’t have permission to access any other external files), and that it only works from the main Pythonista app (it won’t work from the widget or share sheet, because those are separate processes with distinct permissions).

    I see the following output:

    /private/var/mobile/Containers/Shared/AppGroup/5BAD0E84-52A4-4FD2-8008-A2508B4F433F/File Provider Storage/Repositories/my-repo
    ['import os\n', '\n', 'cwd = os.getcwd()\n', 'print(cwd)\n', 'with open(f"{cwd}/test.py") as f:\n', '    print(f.readlines())\n']

    I wondered if there was something undocumented like that! I couldn't find the relevant source code to check though, and my forum-search-foo is lacking. Thank you again!

    Thanks! Someone pointed me to that in the Slack channel too :)

    The cleaned up example will be handy.

    @JonB said:

    when load_view is called inside init, it knows to bind itself to the calling instance

    Oh that's useful! I'll give it a shot when I get a chance. Thanks!


    Hang on. I see a problem with that. If I put ui.load_view() in the custom view class's __init__ and then attempt to use that view with another ui.load_view("my_view") I'll end up in a recursive loop.

    Does that mean that if I do this I can ONLY instantiate my .pyui-defined views by adding them to other views in interface designer? Or have I missed something again? 😄

    Table cell detail labels are read only, and it doesn't seem possible to adjust them the same way we can cell titles (TableViewCell.text_label.text = "Hah!"). Am I missing something, or is there really no way to give table cells detail labels (short of diving head first into ObC-land)?

    If I have a bunch of views defined in .pyui files is it possible for me to reuse these to build more complex views?

    I see that in the interface designer I can add a custom view and set a custom subclass, but that doesn't pull in the associated .pyui file.

    I don't believe so. I think you have to code in the delegates yourself. It's not too bad though. Something like this should work (NB: Not tested).

    import ui
    class MyTextFieldDelegate(object):
        def textfield_did_change(self, textfield):
    textfield = ui.TextField()
    textfield.delegate = MyTextFieldDelegate()

    Please excuse the double post, but this is about a different issue to my last post.

    I note that the OP's version of this script assumes that the x-callback response data will be formatted something like app://xcallbackresponse-REQUEST_ID/?query=value&query=value. But one of the apps I'm working with formats its response like app://xcallbackresponse-REQUEST_IDvalue which causes the URL parsing in this script to break.

    Here is a modified version which handles this case a little more gracefully by setting x_callback_response.parameters to None when it can't parse the URL directly and by creating a new x_callback_response.raw_response_data which is simply the response URL without the app://xcallbackresponse-REQUEST_ID bit.

    I threw some imports in, but now I'm stuck at:

    NameError: global name 'c' is not defined
    # coding: utf-8
    import x_callback_url
    from objc_util import ObjCInstance
    _handler = None
    _requestID = None
    url = "working-copy://x-callback-url/status/?repo=MY_REPO&unchanged=1&key=MY_KEY&x-success=pythonista://"
    def handler(response):
    x_callback_url.open_url(url, handler)

    EDIT: Ahh. Putting a from objc_util import * into my calling module got me over the worst of it. But I still need access to the globals (because with the code above I end up with _requestID and _handler being None).

    EDIT2: Well I'm stumped. I wondered if the leading _ was messing with the global variables (something something name mangling?) so I renamed _requestID and _handler to g_requestID and g_handler, respectively and it worked! Everything ran fine after that. A little later I tried reverting that change (the engineer in me likes reproducible errors) and everything still worked fine, despite my earlier problems. So then I tried removing the extra import in my calling module (from objc_utils import *) and everything still worked fine. So it seems my original issue has vanished without a trace and now I cannot reproduce it.

Internal error.

Oops! Looks like something went wrong!
