text recognition is a bugabear without access to libraries such as tesseract-ocr. if younare willing to let google do the work for you, iirc there is an api for google photos whch will give you ocr

what's the story with ipv6 now? I'm still getting problems indicated by has_ipv6 false

I ended up with this, which functions as expected.

If your app is doing a lot of this, be careful that there may be a memory leak. you may need to use someobject ._cached_methods.clear() for every ObjCInstance that you create inside the callback, which breaks a reference cycle (well, at least untangles it a bit so gc can handle it)

@JonB said:

confdefs.h

No luck in finding confdefs.h or any setting with IPV6.

There is:
PythonistaAppTemplate/PythonistaKit.framework/pylib/_sysconfigdata.py

'ENABLE_IPV6': 1,```

But the header says:

# [omz] NOTE: This is required by site.py, but the values are not correct. # It's a copy of the default OS X _sysconfigdata, but there shouldn't # be much need for this on iOS anyway. # system configuration generated and used by the sysconfig module

So I made an initial script "strip_pylib.py".

This script should be runned in pythonista at the phone.
It will make a "pylib_clean.sh" file, which should be copied to:

"PATH/PythonistaAppTemplate/PythonistaKit.framework"
at the Xcode project.

And then issue:

source pylib_clean.sh rm pylib_clean.sh

(Note: pylib_clean.sh should be deleted in the PythonistaKit.framework folder afterwards,
or there will be problems with signing and sending to App store.)

pylib_clean.sh will delete a lot of files.

After compilation in Xcode, the program did not work.
I had to manually copy back the directory: "/pylib/encodings" from another copy of PythonistaAppTemplate, and then it worked.

The compilation in Xcode is a lot faster. :)

And the app size went from 60 MB to 30 MB.
There are still some files left, but I am not sure why they survived.
