  @mikael Yeah. I'll try. The ui module in pythonista is still not kind of friendly towards me.

  @craigmrock, are your files named the same (myInterface.py and myInterface.pyui) and in the same directory?

  If @omz decides to support silent notifications we could have this kind of feature, with a server sending a remote silent notification received by Pythonista app even in background, without any user intervention.

  Note that Pythonista doc also speaks about silent notifications but meaning local notifications without sound. That's really completely different.

  So, writing 30 bytes to an open file in a tight loop takes maybe 70 microseconds on my crappy iPad3. (I timed by running 100000 writes). Even flushing between writes, very little difference. I doubt you'd improve much by trying to manually buffer-- since python files handle buffering for you, it shouldn't be an issue.

  Opening the file each time, takes about 1 msec per write. I suspect as you get to GB files, the seek time might take some extra time. So don't do that. Open the file and hang onto the handle, and only close it in an error handler or script end.

  I still think there cb module could be problematic. Are the sensortags recording data on their own internal timer, then you ask for data based on a python timer? Or, do you poll for data which triggers a sample?

  If the sensor tags are sampling based on their own internal timer, things could drift because the clocks are different. To check for that, you would as a counter in the sensortags payload that is incremented only when it sends a response (not when it samples)

  @shinyformica try this, it is the way omz wrote dialog: using wait_modal and resetting the view just after.

  import ui from objc_util import * class Popover(ui.View): def __init__(self, *args, **kws): ui.View.__init__(self, *args, **kws) self.width = 200 self.height = 50 self.label = ui.Label() self.label.text = "test" self.add_subview(self.label) self.label.x = 0 self.label.y = 0 self.label.width = self.width self.label.height = self.height def will_close(self): print("popover closing") class MyView(ui.View): def __init__(self, *args, **kws): ui.View.__init__(self, *args, **kws) self.popover = None self.button = ui.ButtonItem() self.button.title = "Show Popover" self.button.action = self.showPopover self.right_button_items = (self.button,) def showPopover(self, sender): print("show popover") if self.popover is None: self.popover = Popover() self.popover.present(style="popover", popover_location=(self.width-100,50), hide_title_bar=True) self.popover.wait_modal() self.popover = None def run(): v = MyView() v.present('full_screen') if __name__ == '__main__': run()```

  @shinyformica, thanks. I will include the weakref version.

  I was also wondering if you had some globals-clearing code somewhere. Remembering some previous threads where the goal was to make Pythonista act like a fresh interpreter starting every time you run a script.

  Or, to look at it in another way, you are resizing the contained Stepper, but not the containing View.

  By the way, there is a pure-Python ftplib module in the standard library, that's probably easier to read than a C version. (ftplib is only an FTP client though, not a server.)

  Thanks to Apple, iOS does not allow dynamic libraries. So, you cannit install c modules after the fact. numpy was compiled and statically linked into pythonista. pandas was not.

  Your next question might be,
  when will pandas be included in pythonista.

  Xcode Template for Pythonista

  I really want to have a new Xcode template for Pythonista 3. I realize that I've already bought Pythonista so I'm not generating new income for @omz.... so I hereby pledge to send money via Paypal/Zelle (or any other method) to @omz to help support his time for the production of a new Xcode template. I'd gladly pay $25 for a new template. I'd even pay this annually if it would be updated regularly.

  Thoughts anyone? @omz?? How can we help get a new Xcode template made?

  Help with setting up awscli on StaSh

  Turns out I could only run awscli once in a Pythonista session.
  Once I run "python3 -m awscli" exactly once in any StaSh instance, I have to kill Pythonista and relaunch StaSh to run the same command.

  I was able to complete "python3 -m awscli configure" when there's no botocore.exceptions.DataNotFoundError error.

  Transcript below:

  I would personally use Requests and BeautifulSoup (both modules are included by default with Pythonista).

  Furthermore, I would set up the HTTP request to use a modified User-Agent value, in order to hide that you're running this from a script, and pose as a regular web browser (note that this is not foolproof, but it helps).

  If you only need the links to the CSS, you can instruct BeautifulSoup to parse only to links, thus speeding up the process, by using the SoupStrainer class (more info here).

  Hope this helps.

  Is possible to run Black on Pythonista?

  I was wondering the same thing, and I finally got this working. I think the problem was with the attrs package. One of the errors made it look like I needed attr (no 's'), but that is a different unrelated package.

  I installed black with Stash pip, as well as attrs and any other package it needed, until I could run black.py without errors.

  I put together this little script to format a document in the editor. I'm sure there's a better way to do it, but this seems to work beautifully when added to the tools menu in Pythonista.

  #!/usr/bin/env python3 """Format editor contents/selection in Pythonista with Black formatter.""" import editor import black import console import time # Options LINE_LEN = 88 # Default: 88 FAST = False # True = skip syntax check # Get text and selection text = editor.get_text() start, end = editor.get_selection() selection = text[start:end] if len(selection) > 0: raw_text = selection else: raw_text = text try: start_tm = time.time() formatted = black.format_file_contents( raw_text, line_length=LINE_LEN, fast=int(FAST) ) except black.NothingChanged: console.hud_alert( f"No formatting needed! ({time.time() - start_tm:.4f}s)", "success" ) except Exception as err: console.hud_alert(err, "error") else: new_text = formatted[:-1] if len(selection) > 0: editor.replace_text(start, end, new_text) editor.set_selection(start, start + len(new_text)) else: editor.replace_text(0, len(text), new_text) editor.set_selection(start, end) console.hud_alert( f"Reformatted! ({time.time() - start_tm:.4f}s)", "success")
