  @omz For à very little shortcut script without any UI, if you launch it via Share, it runs without starting the full app, but if via Widget, it starts the full app.

  @Jason, nice! Creates pretty artsy pictures, in the sense that recognizing the people in the original picture is not likely.

  @Drizzel, some sites are use so much JS that they are hard to scrape with just requests and bs4. If this is the case here, you can use WebView to act as a browser and run the JS. I have a small helper class for this, discussed here.

  In all cases, web scraping seems to be a lot of detective work, trial and error.

  Pythonista 3 + StaSh + Plotly... I'm Close to a meltdown.

  I will also say, that running pip install plotly with latest stash caused pip to install all of the plotly folders into site-packages-3, instead of the plotly folder, which totally borked pythonista, and it crashes immediately upon open, even with safemode and pythonista3://. could possibly be my fault for hitting ctrl-z during the process.

  so... don't do that

  @mithrendal I see thanks. I'll look into it tomorrow, but I think you might be able to move the main_view creation into the global scope (i.e. out of the main function) to make it work, but it's getting pretty late here, and my iPad is busy, so I can't really test this theory right now. I definitely had a working example (just not very pretty) when I posted the last beta.

  +1 for more shapes :). Will look into option of getting the turtle2 lib installed on the class iPads. Perhaps I could have a one liner that references an icloud based lib, so updates can be shared easily between devices...

  The difference is that things like CGRect and the like are structures, not full fledged objects. CGRectMake is not a real function, but an inlined function that gets optimized away by the obj compiler, and so there is nothing to call.

  You either have to find someone who has done the work and converted the library to python ctypes lib that you can import, or else do it yourself. Rubicon is a good place to look for much of the the core stuff

  @JonB That's really interesting, but I can't get it to work. file just ignores my custom ~/.magic file (that works when I pass it with the -m flag).

  @dgelessus The #LyX approach seems to be working on Mojave, though I haven't yet tested with the entire library. Thanks!

  Turns out that the issue is that the interpreter hands out random errors, when a real error exists, but update has tried starting up and resulting timing issue is apparently the cause of the random errors. I was moving the missing attribute setup up in the setup code, and not fixing the hidden code issues.

  The best advice was to comment out update and track down the actual errors.

  Which turned out to be COLS & ROWS set up at the top of the script, were ignored and set up as a local variable in my def Paint_Photos(self) code

  My solution was to declare them as global, still not clear why COLS & ROWS worked in the game example but not in my code! Thinking I should have passed ROWS and COLS to Paint_Photos

  Thanks folks, I could not have made progress without the TLC of @JonB & @enceladus
  (Truly Learned Coding!)

  Btw delaying update simply changed the random errors??!!

  @JonB yeah, changing c_void_p to c_byte still results in a crash with the same fault log, and setting the handler to None also results in a crash with the same fault log.

  By the way, if you are just trying to pause something until the view closes, you would use wait_modal instead.

  Hello! Im having the same or a similar issue with requests/chardet/idna dependencies. I tried deleting chardet and restart the app, but my stash seems ”stuck” when I try to reinstall the package (or doing any other operation for that matter). All I get is ”No module named chardet”, even when I run pip install simplegist (as a simple, seemingly unrelated example?)

  Any ideas?

  @lpl, this should work:

  def at_start(nav_view): nc = nav_view.objc_instance.navigationController() return nc.topViewController() == nc.viewControllers()[0]

  See this thread for more comprehensive set of functions.
