> What I need is an emacs with more lisp and less javascript

Lem[0] in ncurses mode might be your friend. Unfortunately the BDFL deprecated the SDL frontend seemingly due to the SDL3 breakages, but the web one uses webview + a homegrown system instead of electron and framework magic, so it's still fairly lightweight

its main proposition is that the whole thing is written in Common Lisp, so it retains the hackable model of traditional Emacses without retaining the legacy of GNU Emacs
