Status update: Python 3 compatibility for the script is mostly done. There are two main issues remaining to solve:

• I’ve transitioned to using curl for web requests, similar to AutoPkg 2. However, I’m not handling GitHub tokens correctly yet, and getting 403 errors as a result.
• The swift notification listener is not working as expected, causing the app to fail to display the output from a Recipe Robot run if the script raised a RoboError. I may need some help with this one.

Work in progress on the https://github.com/homebysix/recipe-robot/tree/2.0.0-dev branch.

Thanks for the report! It’s true, I’ve been busy updating other projects for Python 3 and neglected Recipe Robot. But I hope to bring it up to date soon.
