Pythonista will run on M1 Macs

It does!

ihf

@cvp Not for my job, for personal use. Good to know Pythonista will run on M1 Macs. Now if only @omz would reappear or make Pythonista Open Source.

@ihf New V00.96 with

Version V00.96
  - deactivation of the whole undo/redo process for testing if it could be 
    the origin of crashes 
    nb: it could not be a vital functionality as it did not work correctly

tell me if you felt any improvement

ihf

@cvp I just downloaded v0.96 ran it and got:

Traceback (most recent call last):
  File "/private/var/mobile/Containers/Shared/AppGroup/05D14C00-CCAC-4E98-A3CC-96C6944B8534/Pythonista3/Documents/outline.py", line 905, in <module>
    PY3 = sys.version_info[0] >= 3
NameError: name 'sys' is not defined

Restarting Pythonista did not help.
P.S. I knew that undo/redo was not working so I stopped testing it as I figured it was on your list.

cvp

@ihf sorry For that, I replaced a lot of import xxx into from xxx import yyy, and I forgot this one

New V00.97 with

Version V00.97
  - correction of bug "PY3 = sys.version_info[0] >= 3 NameError: name 'sys'
    is not defined"

cvp

@ihf could you tell me if you have still crashes during a run of the script,

If you process so:

remove Pythonista
wait 10 seconds
restart Pythonista
run the script

Other question : do you have Pyto, it is open source. I dare not estimate the number of days needed to convert outline.py to Pyto because its ui and its editor are a lot less rich, assuming that all features are supported. But, at least, Pyto it-self is supported and you get updates frequently. I'm always surprised by what a person alone can realize. Even if Pyto is still far from Pythonista, it is obviously a marvelous app for an unique developer.

ihf

@cvp yes, I have Pyto.
I just started outline on my iphone ( I was using it on my iPad yesterday). It crashed Pythonista so I followed the steps you listed and it crashed again. I also tried starting it using pythonista3:// but after I start the script Pythonista crashes. What to do?

cvp

@ihf could you try to get the crash reasons? In fault_log folder or _obj_exception.txt file, both in root

Faultlog, see @dgelessus 's code

For me, crashes have always the same reason "segmentation fault" without any traceback. No way to identify the origin, sorry for you.

Pyto and future Swift Playground 4 would allow to develop an app on iPad...

JonB

@cvp, how repeatable is the crash?

You could consider adding some logging calls to write trace info to a file. Or could use the trace module to for instance log all function calls, then eventually narrow to all lines within a single function.

Have you watched memory at all? For instance, the issue with processing lots of images without doing NSAutoreleasePool. If there is a leak somewhere, it will eventually crash without warning.
Or, maybe if you are opening lots of file handles without closing.

ihf

@cvp @JonB It was completely repeatable but I then decided to try to run a completely different script which ran fine and then I went back to running outline and it ran. If this happens again, I will try to get some better debugging information.

No memory used, it occurs even with a data file of some bytes.
Script uses maximum files, all using "with open(...)"
It occurs even without images, and anyway, I use sometimes maximum 3 images

Strange...very difficult to identify if depends on what we did before 😰

cvp

Following your advice, I've modified my script to write (without buffering) in a outline.trace file all called functions (mine).
I wanted to write inspect.stack()[1][3] but sometimes I got some index errors, thus I tried str(inspect.stack()) and seeing it contains .........function='name', I extract this name and logs it.

You will laugh but as soon I did (only) that, I don't have any crash more. Wait and see

cvp

@ihf New v00.98 with

Version V00.98
  - trace each called function in outline.trace, without buffering

Thus, if you geT a crash, try to describe your scenario and post the outline.trace file, if possible in GitHub, as this file could be very big, else if you crash at begin.

cvp

@ihf It is a long time since we last had a dialogue here.
Some questions I would like you to answer very sincerely:

Are you still using my program?
If so, would you be (sincerely, I insist) interested in running it under Pyto? Becuse you would prefer an open source app (even if I don't see who would continue to modify it)
The conversion to Pyto seems to me an enormous work which would certainly meet impassable walls, therefore which will take months, but which I would accept to carry out for the challenge.

cvp

@ihf As an example, I spent a lot of hours to make my very little module SetTextFieldPas running in Pyto because a lot of functionalities do not exist or differently, mainly ObjectiveC used in this module. If you see the image below, don't believe some code is associated to all these buttons. Nothing is programmed except the buttons themselves.
It was only to find a coherent SF Symbol because obviously Pythonista internal icons are not available.

ihf

@cvp In answer to your first question, I use the app every day! The problems I was having with Pythonista crashing frequently, especially at start up of Outline, have abated. I found that if Pythonista crashed when I started outline, then if I restarted Pythonista and first ran another script, then outline would start without a problem. I don’t understand why this works but it does.
Your second question is harder to answer. On the one hand having outline run in an environment that is supported (even if that means by an open source community) is an advantage. I only use Pyto occasionally and I have no idea how responsive the open source Community is to maintaining it but at least it is possible. I wish that @omz would either reappear or make his code open source but I am not counting on either happening. It would be a shame if Pythonista stopped working under a future release of iOS but that is a possibility. You have put in a tremendous amount of work to create what I view as an extraordinarily useful app. If you are up for the challenge of moving it to Pyto, I am certainly happy to help test it. In the meantime, rest assured that I’ll continue to use the app and I remain in awe of both your willingness to do this and your skill.

ihf

@cvp I would add that if you were up for an even bigger challenge, converting to Swift, would probably be the best course for the app. Of course, that still begs the question of support for the app (not the platform).

cvp

@ihf I agree with all you said (except when you are too kind about me). I could convert to Pyto (obviously with some limitations, and in a period of 2 months) and I wish I could convert in Swift but I think I'm too old to learn this language from scratch 😢

I'm so sad that Pythonista crashes so. Did you test with the V00.98 and did the crash provide a .trace file allowing to hope to identify the crash reason.

ihf

@cvp I may have spoken a bit too soon. As you know I use outline on several devices. I just try to use it on my iPhone and when I started the outline (not when I started pythonista), pythonista crashed. I realized that I am running version 0.97 on this iPhone so I just downloaded version 0.99. There is an error regarding the directories outline.
versions.
