I use Pythonista on iPad and iPhone, and would like to have a common depository for my scripts somewhere on the cloud. Pythonista can export to Dropbox, but it cannot open files from there (at least I couldn't find a way). Copy-paste text will work, but it is clumsy.
I was wondering if there is a way to start editing a script on iPad and then continue working with the same script on iPhone?
Check out shellista, and github. You can use git to push to github, then sync on another device.
I believe the latest development branch is here
https://raw.githubusercontent.com/transistor1/shellista/dev-modular/shellista.py
An older, but maybe more stable version is here
https://raw.githubusercontent.com/transistor1/shellista/master/shellista.py
In either case copy into a pythonista file named shellista.py, then run it.
You then use git commandline to clone from a repo, push to repo, pull in updates, etc.
Full up git is good for syncing entire repos/folders at a a time.
If you are interested in just syncing one file at a time, check out gistcheck
https://gist.github.com/jsbain/1c95b3491d65d9e24456
Which lets you create action menu commands that lets you easily upload, or update the currently edited file to gist.github.com. Also has a bookmarklet that les you go to a gist in safari, then choose the bookmarklet which launches pythonista and downloads the script.
Also, there is a dropbox solution

My recommendation would have been Dropbox Sync instead of GitHub-based solutions.
