Sorry for the cross post, but I thought that this would fit here too.

I have just updated the multifile gist example with my own:

https://gist.github.com/5f3f2035d8aa46de42ad

Save that as "gist" and add the following bookmarklet called "Get Gist" to safari:

javascript:(function()%7Bif(document.location.href.indexOf('http')===0)document.location.href='pythonista://gist?action=run&argv='+document.location.href;%7D)();

Now, whenever you are looking at a gist script that you want to try in Pythonista, just click the bookmarklet and it will instantly download and display the code for you. Enjoy!
