This repository is a snapshot of work-in-progress to modernize IDLE's user interface. These changes are slowly making their way into the official repository...

To try it out, download, either as a zip file or by cloning the git repository. Place everything inside a directory called "idlelib" (this is important!). Open a command prompt, navigate to the directory containing "idlelib", and run:

python3 -m idlelib

As I've been working on this, I've been documenting the changes at http://www.tkdocs.com/tutorial/idle.html.
