Outliner with drag/drop reordering
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.
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
run a completely different script which ran fine and then I went back to running outline and it ran
Strange...very difficult to identify if depends on what we did before 😰
You could consider adding some logging calls to write trace info to a file
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() 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
@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.
@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.
@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.
@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).
@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.
@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.
@ihf yes sorry, I have modified the program to store versions description outside of the code, to win memory, and I did not yet document it here.
Thus you have to download also the outline.versions file from GitHub to the same directory as the .py
New V00.99 and outline.versions with
Version V00.99 - move versions descriptions from script to outline.versions file
@cvp I posted the outline.trace after outline crashed at startup (twice) as an issue on github (in cvpe). This is on the iPhone.
@ihf I had seen and answered in GitHub but here is my answer:
Finally, this trace does not help me....sorry
The set_content_inset function only contains one line which could not crash. I already have thought to modify all my script without the ui.TableView by building my own scroll view and sub views for all rows.
Long work and one disadvantage: all cells have to be created at start, not when they are displayed, but I think that TableView generates some bugs. I think, buT far from to be sure, that ObjectiveC methods I use for this TableView generate all our problems... Thus, I plan to try to rebuild the script, but not for next week (not a lot free) hoping you can still use actual version.
@cvp thanks. I will certainly continue to use the script. Have a great weekend!

@cvp Are you logging function enter AND exit? What could have happened is set_content_inset was the last method called, but then whatever the calling function was failed
@JonB we are not yet sure, we only one trace that the crash is always at same line
@on_main_thread def set_content_inset(self,bb): mytrace(inspect.stack()) # Standard TextView has a top positive inset by default ObjCInstance(bb).textContainerInset = UIEdgeInsets(0,0,0,0)
called in TableView_cell_for_row but a lot of lines after that...I can't trace all
See a comment "a lot of segmentation errors when we scroll"
Sincerely, as the errors are not reproductive, il is almost impossible to debug.
self.set_content_inset(bb) bb.row = row ObjCInstance(bb).tv = bb bb.text = txt bb.text_color = 'blue' #bb.border_width = 1 bb.font = ft bb.number_of_lines = 0 #bb.frame = (x,0,self.width-x-4,ft) w = bb.width bb.size_to_fit() ho = bb.height bb.frame = (bb.x,bb.y,w,ho) #print('bb:',self.font_size,ho) if self.select: bb.touch_enabled = False else: swipe(bb, self.swipe_left_handler,direction=LEFT) swipe(bb, self.swipe_right_handler,direction=RIGHT) #bb.border_width = 1 cell.content_view.add_subview(bb) if not hidden: # separation line if self.show_lines_separator == 'yes': sep = ui.Label() sep.frame = (0,hrow-1,self.tv.width,1) sep.border_width = 1 sep.border_color = 'lightgray' cell.content_view.add_subview(sep) self.redraw_textview_attributes(bb,opts) # a lot of segmentation errors when we scroll (which set_cursor) # does only if last action = add row if row == self.cursor and len(self.undo_multiples) > 0: if self.undo_multiples[-1] in ['CR','tab','back']:# or (row == 0 and txt == ''): bb.begin_editing() ui.delay(partial(self.textview_did_begin_editing,bb),0.1) c = self.cursor if c >= len(bb.text): c = max(0,len(bb.text)) #bb.selected_range = (c,c) # Pythonista does not allow to set c = len(text) to put cursor at end range = NSRange(c,c) ObjCInstance(bb).setSelectedRange_(range)
@ihf New V01.00 and outline.versions with
Version V01.00 - add some traces in tableview_cell_for_row at place supposed to be crash origin
@ihf New V01.01 and outline.versions with
Version V01.01 - use only one InputAccessoryView and share it for TextView of each row, adviced by @jonB to gain memory
@ihf Finally, I feel too lazy to convert the TableView to a ScrollvView, with the risk of encountering the same scrolling issues. On the other hand, I am always available to continue to try to correct problems if they are clearly identifiable.
@cvp this is not at all urgent but perhaps you could add it to the to do list. I wanted someone else to try out outline and I realized that there are several files that they need to download in order to make it work. Would it be possible to either check for those files and download what is needed in the script or if that doesn’t make sense, perhaps a set up script that they could run once?
