Python 3.x Progress Update

Thanks @omz This is now on my shopping list.

It would also be interesting to have a poll to see which version (2 or 3) is more preferred. I personally will most likely to stick to Python 2 for a while.

This is great news! Can't wait to play around with it. Are ctypes and objc_util working yet? ;)

I assume the device requirements will be the same as for Pythonista 2? (I'm still hoping for iOS 7 support to magically come back so my iPhone brick can run the new Pythonista, but somehow I think that is unlikely.)

omz

@dgelessus Yep, objc_util and ctypes are working well. objc_util was actually somewhat tricky to port because of the way strings are handled in ctypes, but I think that I have most of the kinks ironed out by now.

The requirements will likely be the same as for 2.0. iOS 7 support won't come back, I'm afraid.

Great news @omz! I'm in for both buying and beta testing!

Curious as to how accessing files between versions will work…

omz

@Webmaster4o It'll technically be similar to how files are shared between the main app and the extension now. All documents already live in an "app group" folder that can be shared between multiple apps (you may have seen that the absolute paths of your documents contain "AppGroup").

So basically, if you have both versions installed, you'll see a "Pythonista 2" folder in Pythonista 3, and a "Pythonista 3" folder in Pythonista 2. That's my current plan anyway.

I really need to get some more iTunes gift cards. On my list of apps to buy include Textastic both for iPhone and iPad, as well as Codea, and now Pythonista 3 😂

This is GREAT, I plan to buy the new Pythonista as well!!!! and join the Beta program

@omz Great news!! I look forward to moving as quickly as possible to Python 3 only. Pythonista was the last thing keeping me on Python 2. I run the Anaconda Python 3.5.1 distro on my Mac and just love it. It will be fun to unify on Python 3 on all platforms. I look forward to the beta program and to buying Pythonista 3 as soon as it is available. Congratulations!!!

Great news!

This is great news!

That's awesome! I'll definitely get that version as well, as I'll just switch to it asap :P

Great news @omz, can you share a link for beta signup?

I expect that I'll have the first beta ready within the next week or so, hopefully without some of the limitations I've listed above. I'll post a new beta signup form here when I'm ready.

Awesome. Now I'm going to have to change

 print "something"

statements in my scripts for months to come as I run them only to find my lazy ass didn't use

print("something")

But seriously I'm glad Pythonista is moving forward as it's probably for the best. Now when will OS X ship with Python 3 out of the box???

Also @ccc any reason in particular you use this Anaconda distribution? Is that what you would recommend for everyone on OS X?

There will be some way to automate this.

There's this thing called lib2to3, I hear it's part of the Python standard library. Perhaps that might be useful. ;)

@omz Maybe putting a lib2to3 thing in the action menu would be useful? Like the "Convert Indentation" option, except that it runs 2to3 on the file. Would probably be good to save the output to a different filename though, lib2to3 isn't perfect and doesn't always produce code that can run on Python 3 right away.

@Tizzy -

@omz said

It will be possible to access files in Pythonista 2.x from 3.x though (and vice-versa).

He said in more detail on twitter that there would likely be a folder in the file browser for the 3.x version which simply displayed all of the files from the 2.x version. I suggested on Twitter that a dialog could be displayed for importing files from the 2.x folder, which would contain an option to automatically run the 2to3 program on the files imported. We'll see if that's something @omz chooses to implement.

Yes, I've implemented pretty much exactly that. Right now, it doesn't make a backup, but the changes are undo-able, and it shows a diff before applying them.

any reason in particular you use this Anaconda distribution?

http://docs.continuum.io/anaconda/pkg-docs lists all the superpowers that Anaconda adds to Python for free. 150 pre-tested, pre-configured modules. Just the IPython/Jupyter function alone is super cool but there is soooo much more in Anaconda.

Is that what you would recommend for everyone on OS X?

Mac OS X, Windoze, Linux. Yes!
