Xcode Template for Pythonista

amdescombes

Hello everyone,

Here is a reworked script that adds the comments at the top but preservers coding= comments.
It is not perfect, but it helped me succesfully submit an app to the Appstore, I hope it is of help to every one.

#import pythonista
# Change the ********** to point to the directory containing the Pythonista framework :
project_path = '**********/PythonistaAppTemplate'
pylib_path1 = '%s/PythonistaKit.framework/pylib' % project_path
pylib_path2 = '%s/PythonistaKit.framework/pylib_ext' % project_path
MAX_REPEATS = 10

import shutil
import os
import subprocess

def check_is_executable(file_path):
    file_output = subprocess.check_output(['file', file_path])
    if 'executable' in file_output:
        return True, file_output
    return False, file_output

def fix_executable(file_path, dry_run=False):
    with open(file_path, 'r') as f:
        source = f.readlines()
        if 'coding:' in source[0].lower():
            firstline = source[0]
            start = 1
        else:
            firstline = ''
            start = 0
    if dry_run:
        if firstline:
            print(firstline)
    else:
        with open(file_path, 'w') as f:
            f.write(firstline + '#import pythonista\n' * MAX_REPEATS + ''.join(source[start:]))
    is_executable, out = check_is_executable(file_path)
    return not is_executable

def fix_pylib(pylib_path, dry_run=False):
    print ("fixing", pylib_path)
    for path, dirs, files in os.walk(pylib_path):
        print(path, dirs, files)
        for filename in files:
            full_path = full_path = os.path.join(path, filename)
            is_executable, file_output = check_is_executable(full_path)
            if is_executable:
                extension = os.path.splitext(full_path)[1].lower()
                if extension in ['.py', '.pym'] or filename == 'command_template':
                    if dry_run:
                        print '### Executable found: %s' % (filename,)
                        fixed = fix_executable(full_path, dry_run)
                    else:
                        print 'Fixing %s...' % (filename,)
                        fixed = False
                        counter = 0
                        while not fixed:
                            fixed = fix_executable(full_path)
                            counter += MAX_REPEATS

                        print 'Fixed with '+str(counter)+' dummy lines.'
                else:
                    print '### Executable found, but does not seem to be Python code: %s' % (full_path,)

if __name__ == '__main__':
    fix_pylib(pylib_path1, False)
    fix_pylib(pylib_path2, False)

Cheers

so, this may be a stupid question, but my understanding of this problem is that file is running locally, and is getting rejected locally.

so, why not just edit /usr/share/file/magic (or copy it, edit it, then file -C to compile it to a new .mgc), or create an alias to file with a -m argument pointing to your custom magic file. It should be possible to edit the entry for pythonm or add custom search for the shebang or coding lines, to simply output a safe mimetype,

Hi Jon,

I think that is a very good question and a very interesting option to explore as it would avoid modifying the framework. I'll look into it as soon as I get a chance and report my findings back.

Cheers

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?

@TheRealBret Good news!
@omz said:

Here's a first attempt at a Python 3-based Xcode template: https://www.dropbox.com/s/5l94m0xjbot5je0/Pythonista3AppTemplate.zip?dl=1

This is roughly equivalent to the current App Store version (not the 3.3 beta), and not final, just something to play around with for people interested in the Xcode template. Let me know if anything's unclear.

TheRealBret

Indeed - I’m very happy to see the new template. Thank you!

My offer still stands - I would like a way to give a donation to @omz to help offset continued development of Pythonista. I can’t see how my payment a year ago is helping today.

Is it possible for someone to upload a version of the template for python3 with the fix to include the line at the top of all the files already done? I am having lots of trouble doing it myself.

Any update on the template? As of April 2020 the template is completely broken since it uses the deprecated UIWebView API which is not allowed anymore: https://forum.omz-software.com/topic/6474/python3-xcode-template-broken-because-of-deprecated-uiwebview

JonB

Is the binary signed in some way? I wonder if you were to edit it in a hex editor, and replace UIWebView with some other nonsense class name (same number of characters).
Since objc is message based, there is nothing linked to support UIWebView, just a runtime call with a c string with the classname. As long as you never instantiate a webview, things won't crash.

@ruohola sorry this is a little late and I hope this information is still relevant for you. I took @JonB 's advice and went into the P3kit framework and edited the P3kit file. For me it popped up as a unix executable, so I needed to download a hex editor to go in and modify it.

All I did was command-F and find all the instances of UIWebView and replace them all with UIBarItem. This is an API with the same character length and the API isn't deprecated. Save the file and make sure it is still in your project directory.

I archived and uploaded my build last night and the App Store did not reject the build. so this is a good working solution. My app is a 2D shooting game called Flyboy Adventure Game and it is currently under beta review as we speak. I've tested my game on Testflight and it works great, so hopefully there is no long term repercussions from using this workaround.

@coltonboyd, thanks for sharing, this is great news. I am (again) tempted to put something to the App Store.

@mikael

Of course, just for reference the Hex editor I used was SlickEditPro2019. You can download a free trial and it’s pretty easy to use.

I’m currently trying to upload a updated Pythonista 3 Template to my Dropbox but it’s taking forever.

JonB

@coltonboyd It might be good if you could document the various steps you went through from start to end -- for instance did you have to do the workaround so file doesn't flag .py files as executable? Anything else you had to modify from the template?

coltonboyd

@JonB I’m glad you mentioned that. I forgot to inform that to get past signing errors I used @RomSpy ’s last template he posted from this forum link:

https://forum.omz-software.com/topic/5837/xcode-template

After getting past the signing errors is when I started getting the UIWebView deprecated rejections from Apple. That is when I stumbled upon this forum post and tried out your idea of downloading the hex editor, etc. I first tried replacing UIWebView with WKWebView like Apple suggested, but it ended up crashing my app after launch. Replacing it with UIBarItem had no effect.

Here is my latest version of the Pythonista 3 App Template that I used for my game I’m currently publishing to the App Store as we speak.

@coltonboyd said:

Thanks! But it seems that you upload version with WKWebView. I changed that to UIBarItem and it worked

coltonboyd

@vovaburm oops I must have uploaded the wrong version then off my desktop, my bad! I’m glad you got it to work!

coltonboyd

To anybody that needs it, here is the correct and updated Pythonista 3 Template:

@coltonboyd the last link you posted doesn't work :(
