Appex GetFromURL to share from other apps to Pythonista
-
I played around with the beta 1.6/soon-to-be AppStore 2.0 appex module, which provides a way to make application extensions in Pythonista for use on the share sheet in other apps. Pretty amazing stuff! See module documentation and included examples for details, also on how to make available on the share sheet.
Then I realised this could be a way to collect files on the web (share in Safari), but also in cloud apps (share in Dropbox), in external editors (share in Textastic should you prefer that to the Pythonista IDE), etc. Actually, Appex GetFromURL.py works pretty simple: get url byappex.get_url()
, get data byurllib.urlopen().read()
, store data byopen().write()
. The script's length is mainly caused by path manipulation, error handling, and reporting progress.
This probably has been done before, but you may find it helpful, so here it is. Comments are welcome. -

Wrote more flexible version of your script: Open in Pythonista
My extension allows save into Pythonista from different sources:
- from app extensions:
- single files or entry directories, passed by file path
- single files or web-pages, passed by URL
- text data, passed as raw text (e.g. from Notes app)
- from Pythonista's Editor:
- text data of opened tab
To use this extension you also need to download and install (copy into the same folder) libs package (to be precise: misc and log modules) from the same Gitlab project.
I'll be glad to feedbacks =)
