• 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:


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

    There is:

    '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:

    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.

Oops! Looks like something went wrong!
