Version V01.04
  - correction of bug "keyboard was disappearing after an enter 
    to create a new outline row"

This bug was not so old, it should have appeared from V00.96 when I removed the undo/redo process and a part of this process variables is checked for cursor process.

@ihf said:

when I type a new outline item, and I hit the return, the keyboard disappears. I think it would be better if the keyboard remained so that you could continue typing since you are positioned on the next outline line. Does that make sense?

Yes sir. I had remarked this problem yesterday, sorry for you. I'll try to correct it tomorrow.
That should be an old bug and I can't remember if I have already tried to solve it, and if yes, obviously without success

@sgspecker This allows to create a new photo with updated caption in camera roll if you share an existing photo which has already a caption

import appex
import console
import os
import photos

def main():
    if appex.is_running_extension():
        fil = appex.get_attachments()[0]
    else:
        fil = 'a.jpg' 
    with open(fil, mode='rb') as fin:
        b = fin.read()
        #b'\xff\xed\xllllPhotoshop 3.0\x00' = marker APP1 
        #           -----

                    i = b.find(b'\x1c\x02x', i8)                    
                    # caption field identified by x'1c0278' then length in 2 bytes x'0005' = 5

                    # store new caption

@JonB said:

are you holding onto a reference to the text view itself?

No but I store the TableView row into the InputAccessoryView. Then, when a key is pressed in the supplementary keyboard row, I can call textview_should_change with the right row which is the index in TableView. And I don't need anything more, even the TextView it-self.

**cvp**

@JonB sorry, never seen this post. I'm in holidays for some days. i'll answer this weekend

**cvp**

@sgspecker here how to get the caption

from PIL import Image
import appex
fil = appex.get_attachments()[0]
with Image.open(fil) as im:
    for segment, content in im.applist:
        if content.startswith(b'Photoshop'):
            # caption field identified by x1c0278 then length in 2 bytes x'0005' = 5
            i = content.find(b'\x1c\x02\x78')
            l = int.from_bytes(content[i+3:i+5], "big")   
            caption = content[i+5:i+5+l].decode("utf-8") 
            print(caption)
            break

**cvp**

@JonB I didn't think to update it, I was already happy to find a begin of way to get the caption.

I think these infos are not stored in the photo file.
If I import the same photo in Pythonista, these data are no more there.

**cvp**

@sgspecker First of all, I don't know anything about this matter, BUT, after some Google searches and a lot of tests, I've discovered that the caption is passed into the shared asset.
Try to share a photo where you have typed a caption to this little Pythonista script.

@JonB never say never 😀

For your info, it is not stored in the EXIF's but in the IPTC fields.

from PIL import Image
import appex
fil = appex.get_attachments()[0]
with Image.open(fil) as im:
    for segment, content in im.applist:
        if content.startswith(b'Photoshop'):
            print(f"segment={segment}, content=Photoshop...")
            ls = content.split(b'\x00')
            for l in ls:
                print(l)

You will find in the output the caption you typed. I don't yet know how to identify the right field where it is stored, but it should be possible to do it.

@ihf said:

The menu that permits setting bold, italic, etc. is no longer coming up.

You know that some text needs to be selected first.
If so, and you select "bold..." in the popup menu, that works.
But the "bold" key does not work.

It seems that from V01.01 where I had put a modification to share the same InputAccessoryView for all rows prevents the keys of keyboard extra row to work. Not only the "bold" key but also promote
and demote keys.

Thus next version will remove this modification.

V01.03 and outline.versions with

Version V01.03
  - remove sharing of one InputAccessoryView (set V01.01) which prevent keys of
    keyboard extra row to work

**cvp**

@ihf V01.02 and outline.versions with

Version V01.02
  - check if all imported modules exist and, if not, print their list
    and url's where to find them

Not sure all are there but wait and see with first new user.

Added in my todo list to automatically download missing ones but not for coming days.

List is
