Stuff like this always amazes me and makes me glad i switched to Emacs not too recently ago. I begin to grasp why Emacs is its own OS and that's even a nice thing! (fwiw, nowadays Emacs is my mail client and my go to editor/IDE)

Welcome to the fold. Emacs is basically a lisp image with a built-in text editor. You can even write web servers in it (and people have).

The utility of such a system beyond just editing one or text files at a time is enormous.

Enjoy your stay.
