Update (2021-10-16): While this list was intended as a demonstration of the kinds of things you can do with Embark, there has been some interest by readers in reproducing these demos exactly on their machines. So I have added a “Play by play” section under each demo listing the sequence of actions in the demo. Embark is a fantastic and thoughtfully designed package for Emacs that flips Emacs’ action → object ordering without adding a learning curve.
