Wish list for post 3.3...

Zoot

It's awesome to have official 3.3! Best iOS app ever.

Things I would love to see in the future...

1 A dark mode for the built-in documentation so I don't turn to dust when I open it every time.

2 Ability to do a split-screen view showing the Console REPL and a documentation viewer at the same time to allow little experimental doodles while reading the manual.

3 Python 3.8.x of course. But having only 3.6 is hardly a big limitation at the moment.

Things like Pandas and scikit-learn (or even TensorFlow/PyTorch as long as we're dreaming) would be cool, but honestly, I'm pretty happy with the libraries and functionality that's there today. I use Pythonista mostly as a portable testbed for standard Python stuff that ends up on another platform rather than either for iOS app development or trying to do on-device-data-science. I find it the perfect companion for reading Python documentation or books.

Also, I would not be bothered in the least if Python 2.x were dropped completely.

Automated formatting and linting (that I can turn on or off). If there is no new user input for x (3?) seconds then isort —> black —> flake8 is run to format and lint the code in the editor. There is a button in the UI (top of the keyboard?) to perform the same steps on demand.

Hope can add:
1. Comment/uncomment [ cmd+\ ] shortcut;
2. [ctrl+up/ctrl+down] for Page up/down;

Up to date pre-installed modules

I'm pretty new to using Pythonista, so this may be possible and I just haven't discovered the key to it:

  • Compiler to export my scripts to a stand alone iOS app. (big wish, but a wish none the less).

I'm using Pythonista to automate processes so the code I build for iOS will typically be used by someone in their work. Getting to a single icon to start the apps would be a huge boon.

@KipCarter https://github.com/omz/PythonistaAppTemplate was that capability but it has not been updated in years.

KipCarter

@ccc , Thanks, would be nice if it were updated to handle 3x code.

Not exactly what you want, but as workaround, you can, on an iPad, use split view with Safari on Pythonista doc and Pythonista console

Zoot

@cvp Yeah, that might be good enough as a general solution these days. Just doesn't work on my crusty old iPad Air. Oh well.

cvp

@Zoot (not so) quick and (as usual) dirty script to allow a split screen with local documentation and console REPL mode, thus without needing split view of Pythonista and Safari.

top right buttons = navigation in doc
main view is presented as sheet to allow transparency
as console command and output area is overriden by main view,
their buttons are actionned by user buttons at bottom left
1) edit button to put cursor in command textfield
2) previous and next history

y-position of user buttons change when keyboard (dis)appears
program automatically sets console in partial screen

Please, try and give me some feedback.
Thanks

And, one more time, this app is marvelous, you can (almost) do anything

Possible without creating a standalone app, via standard Apple Shortcuts app, if you agree that the user buys Pythonista and you share your source code.

mikael

@cvp, wow! You are the hacking wizard.

How did you find the path to the doc bundle?

cvp

@mikael After opening the doc tab (with ?), Î've analyzed the tree and I found this

 b'RoundedShadowContainerView'
   b'UIView'
   b'UIView'
   b'UIView'
     b'UIView'
       b'UIView'
         b'UIWebView'
           b'_UIWebViewScrollView'
             b'UIWebBrowserView'
             Pythonista Documentation
Welcome! This is the documentation for Pythonista. It is based on the official Python 3.6.1 documentation and includes information about additional modules that were developed specifically for Pythonista. 

Then, I made a dir of the UIWebBrowserView, and one of its properties (I don't remember which one) gave me this url.

'zip:///private/var/containers/Bundle/Application/34BAEE1A-BC33-4D6F-A0C1-B733E4991F31/Pythonista3.app/Documentation.zip/py3/index.html'
mikael

@cvp, so, no big deal, easy to find, well documented. :-)

cvp

@mikael Sure 😅
My only hard/long (for me) work was to try to
1) open the console in partial screen (already solved in a previous topic)
2) present a view without hiding the console, even if you can't really access it
3) simulate tapping the command TextField
4) simulate tapping the previous/next history buttons
5) move my own buttons up/down when the keyboard (dis)appears

If I didn't' find the url, I would set the web doc url

cvp

Be careful, my script has a bug if the standard doc tab is open when you start the script.

omz

@cvp I'm quite impressed by your reverse engineering skills. Very clever! 👍

cvp

@omz Thanks, only patience and enough free time 😀
Only clever thing is your marvelous app which allows to realize such process.

cvp

@mikael Property to find url was

            if 'UIWebBrowserView' in str(sv._get_objc_classname()):
                #print(dir(sv.webView()))
                print(sv.webView().mainFrameURL())

This is quite a good hack @cvp. Every problem looks simple once you solve them so this is not as easy as you make it look. My Pythonista wish list is for the app to reveal the secret of the afterlife because we only live twice. This means that to me Pythonista is already a dream come true that allowed me to achieve many important goals using an iPad. It is good as it is and whatever comes next is welcomed. However, please do not remove Python 2.xx.

ccc

I was all good up until please do not remove Python 2. It is dead, people. It already lived its two lives. Look at the issues just in this past week on this forum which are about Unicode encoding. Let's allow that stuff recede into the past where it belongs. Drop legacy Python because it is legacy.

cvp

@ccc I understand that you/we want to use the latest Python level, but I don't understand the disadvantage to also keep Python 2 support in Pythonista for people who want it.
I say that I don't understand, not that there is no disadvantage

cvp

@Ti-Leyon said:

I agree, that's why I said it was hard and long for me 😅

Ti Leyon

Tools never die @ccc. Will the concept of a hammer or that of the screwdriver die at some point? Even the basic lever is still useful when you only have a stick and a rock to lift a heavy weight. Python 2.xx will always be as useful as it ever was. I went over that discussion with you and others many times as you may remember. No one has ever provided a valid reason for the removal of Python 2.xx from Pythonista. Basic impulses can not dictate the direction of a logical entity (Pythonista).

Ti Leyon

@cvp like the french philosopher Deleuze said: "Il fallait y penser!".
