Someone posted the wishlist the ability to add interactive local notifications.... so this was this evening's distraction.

The basic idea is that you have to override the app delegate with a custom version. (it should have been possible to add a method to the existing delegate, but this always caused a crash for me). Of course, this only works until ios decides to unload the app from memory, or you actively kill or crash the app, since the delegate is not permanent. As such, it is probably less useful than regular notifications.... omz would need to provide a way to hook delegate calls to python functions (specific file in site-packages, say).

One note, I had to override the type encoding, because the @? type for a Block caused a TypeError when called... so I replaced this with a regular pointer @ and used ObjCInstance to convert to a Block to .invoke() the completionhandler.

I have been toying with various ideas for a pythonista debugging system for a long time, to replace pdb in the console. With ObjC, we can finally integrate this into the editor itself.
Here is a working, albeit not yet complete, visual debugger. right now it supports stepping in/over/continue/quit, as well as a Locals/Globals display (read only right now).

I have separately working an overlay system for setting breakpoints by tapping the line number, though this is not yet fully baked and is not integrated into the main class yet (see inwork folder) I think I want to also go back to my older line highlight method (currently using editor annotations, but the "warning" is not overridable and interferes with the interface a bit)...

Anyhoo, here's the Readme/install/screenies:

Visual Debugger(vdb)

interactive debugger inside pythonista editor

##features

• single stepping, or step over
• continue, or quit
• watch window (view only right now)
• During debugging, current line is highlighted, and editor opens new file if needed

##TODO:

• breakpoint set/clear by tapping line s
• launch script via menu
• stack up/down
• help menu
• optimizations for small devices

usage (where debugging is needed)

	import vdb
	vdb.VDB().set_trace()
	

##install
Thanks to @ywangd for this method.

Thanks, but does it have a user forum where people can ask and answer questions?

https://github.com/jsbain/viewbrowser.git

Inspired by the UIDebuggingInformationOverlay, which I couldn't get to run on my 32 bit device, this is an overlay that allows exploration of the UIView heirarchy. Add to wrench menu for easy access. Mainly for exploring pythonista internals, but can also be used for views presented from the ui module.

Tapping a view highlights the view in red, making it easy to find where you are. Currently hidden views are greyed out. Expanding a view shows its subviews. For buttons, or other views with gesture recognizers, tapping the link button shows the action and target(prints to console for now) -- useful for determining the objc methods to simulate button taps, etc. (@zrzka, you have probably figured out everything you want to simulate for blackmamba, but if not, this might be helpful)

The info button opens an objc object browser, which shows all of the properties of the instance. Tapping on a property that is an ObjCInstance opens that object in the object browser, and so on.

The object browser is still somewhat experimental, and sometimes crashes for properties that return a different objc object for each call -- since i currently do not store the actual instance, but instead use the address, so if the object is gc'd, tapping on its rowresults in a segfault. I may change that (though it also seems like it could be a bad idea hanging onto strong references to a bunch of objects)

With the addition (in latest master and dev brsnches) of the new gh command for interfacing with github (create, fork, or issue pull requests), I figure it is time to start writing down some simple git in stash tutorials. This is probably also a good way to expose and work on the remaining bugs in the stash git implementation.

https://github.com/jsbain/stash_git_tutorial/blob/master/stash_git_tutorial.md

see http://wa5pb.freeshell.org/motd/?p=769 for an example of creating a watermark with reportlab, then applying it using PyPDF ( or PyPDF2 in our case)

both reportlab and pypdf2 are included with pythonista

I don't have an iphone to test this on, but you could try this:

# coding: utf-8
from objc_util import *
app=UIApplication.sharedApplication()
rootVC = app.keyWindow().rootViewController()
tabVC = rootVC.detailViewController()
tvc=tabVC.selectedTabViewController()
ed=tvc.editorView()
tv=ed.textView()
tv.showLineNumbers=not tv.showLineNumbers()
#not sure how to force a redraw.  changing frame size works
oldframe=tv.frame()
newframe=oldframe
newframe.size.width-=1
tv.frame=newframe
import time
time.sleep(0.1)
tv.frame=oldframe

maybe use in an action script, and it should toggle line numbers in the current tab. Not sure if the view heirarchy is the same on iphone, so maybe this won't work.

press and hold the play button, it will pop up a dialog asking for arguments.

from objc_util import *
>>> defaults=ObjCClass('NSUserDefaults').standardUserDefaults()
>>> defaultsDict=defaults.dictionaryRepresentation()
>>> defaultsDict['UseSoftTabs']
<b'__NSCFBoolean': 1>
>>> defaultsDict['IndentationWidth']
<b'__NSCFNumber': 3>

type defaultsDict at the console to see all of the pythonista settings that you can check this way.

@Ti-Leyon Actually, any devices still running python2.7 will instantly explode, into flames, possibly ending your life. The PSF does NOT mess around.

To set the focus point like you would tapping on the screen:

See
https://developer.apple.com/documentation/avfoundation/avcapturedevice/1385853-focuspointofinterest?language=objc

device.lockForConfiguration_(None)
device.focusPointOfInterest = CGPoint(0.5,0.5) #center of screen
device.focusMode = 2 #For continuous autofocus 
device.unlockForConfiguration()

There are some other options, like setting a focus range if you know what the acceptable range is, etc. You can set single autofocus instead of continuous, which does it once then locks it. You could also choose a different point. There may be some options to let the phone choose a subject automatically, then set focus point based on that, but that's more complicated.

@Ryoeli said in Running mp3, m4v files in Pythonista:

Pythonista has had major improvements with the recent updates so I’m bringing up again a question that I’ve seen posted in the past : is there a way today (that works!) to call in and play on call inside the code short mp3 or m4v sound clips?

Id imagine this maybe could be done if you have a headphone jack, and modify a headphone cable to route the headphones to mic in.

Alternatively, you could wire iPhone A output into iPhone B input. Though do any iPhones still have hardwired jacks?

@resserone13v2-0 you can always search stack overflow for your error

https://stackoverflow.com/questions/63460126/typeerror-type-object-is-not-subscriptable-in-a-function-signature

There are a few workarounds depending on the version you are using.

@bensaccount when looking at the apple docs, if you click on the name that you want, then switch the mode to Swift, it will usually show you the corresponding number.

There are also many places that have searchable iOS header files. If you find the header that has the enum you want, it will show the names in order.

NString constants can often be found using the in_dll method that was in dgelessus's post that cvp linked to.

@kendals also, numpy comes pre installed with pythonista. You will need to delete that folder.

You cannot install and run any packages that require compilation. Apple rules.

@starmix there are a few threads here on how to use the code templates. The most recent is here:

https://forum.omz-software.com/topic/8093/xcode-template-for-python-3-10

Note that the template linked in the thread is based on python 3.6, so you can't use some of the 3.10 features.. perhaps @omz will release a 3.10 template so that what you test in app vs what you try to package are the same.

@Niall looks like they haven't upgraded to python 3.9 yet.

Replace the falls to unescape from HTMLParser objects with

import html
html.unescape

See the workaround near bottom of this
https://github.com/PySimpleGUI/PySimpleGUI/issues/4119

You have to edit gui.py in your remi folder (site-packages/remi), and make the suggested changes.

can you post the full traceback?

@Niall that is just a warning. See https://github.com/PySimpleGUI/PySimpleGUI/issues/3663
Don't know why they never fixed that, but probably doesn't affect things. .. it should probably be something like

if (image_size[0] is not None) or (image_size[1] is not None)

But I'm not sure. Since they never bothered fixing it, I'm guessing it isn't causing issues.

@Niall ok, I haven't tried yet, but I can't think of a reason why the web version wouldn't work on pythonista. You'd need to launch a webView for display, but it looks like remi is pure python, and pysimpleguiweb ought to work.
