Gist to GDrive for Google Apps Script

Download/Backup your gists to a GDrive folder.

Setup

Prepare your Script

First create a new Google Apps Script. Get your Script ID in File > Project properties. You will need this for the OAuth.

Set the rootFolderPath variable to the target folder name where you want to download your gists. Optionally add a parent or two to prevent duplicate findings.

In Resources > Libraries... search for the library:
1B7FSrk5Zi6L1rSxxTDgDEUsPzlukDsi4KGuTMorsTQHhGBzBkMun4iDF
and click on Select.

OAuth

Get a Github ClientID and -Secret from: https://github.com/settings/applications/new
Your callback url is: https://script.google.com/macros/d/{SCRIPT-ID}/usercallback
(Here you need the Script ID from the previous step).
Add your clientID and clientSecret into your script (replace the ...).

Run

Run the run function and open the logs (Cmd|Ctrl + Enter) after getting an error message. In the logs open the OAuth url in a new tab. If everything was successful run the script again and keep an eye on the logs.

If you run your script again the script just updates the previously downloaded gists if they have changed. This way the script does take much less time and if you get a timeout error you can just run the script again to continue.

New: Removes old (removed or renamed) gist folders.

Add triggers (cron jobs)

Click on Resources > Current project's triggers to add the run function as a Time-driven trigger. You could execute it once or twice a day to stay updated (depends on your gist activity).
