4 points · Open discussionAhh, I finally get to flex. With our powers combined, me and a random unknown dev successfully set up a Python REPL that has access to emacs. I.e. you can program emacs via python:

Maybe this'll be the boost you lurkers need to get your butts into one of the coolest editors. "Not your dad's editor" -- new emacs slogan, probably. /s
Bonus screenshot of compiling emacs on a 96 core TPU: https://i.imgur.com/YtJ8jF7.png
It launches emacs, then uses the (relatively) new dynamic modules feature to start a Python runtime, which can then import a library that accesses emacs.
But to my surprise, Python can also import whatever you already have `pip3 install`'ed. I import

ed jax and did some high speed calculations in lisp. Just kidding, I really did import jax, but it'll take a bit more work to be able to pass numpy arrays to emacs. :) But it's "just" a matter of making some kind of RPC system so that (+ a b) ends up calling back into python to do the addition. Then the circle will be complete -- elisp from python (already done), and python from elisp ("exercise for the reader").
For real though, go throw that fella a star on his github repo. The most surprising thing was that this project has been quietly on github for like two years already. It was sitting at zero stars when it popped up in one of my random google searches.
