It appears to be an #emacs-ish program that uses #commonlisp for customization.
Apparently there have been other emacs clones based on #go and #rust and I guess those are called #emacsen ?
Without going too into my personal details, I’m not a professional programmer and most of my experience is with a modern programming language, #swift, and a high level programming language, #python.
I’ve tried learning #elisp several times by completing various programming exercises and I end up quitting because something obnoxious comes up that, from my minimal programming experience, appears to be due to elisp‘s age. Again, I’m not a pro, so this is just my amateur take.
I did a some programming challenges with #clojure which was hugely fun (mostly because of how fun it feels in emacs 😁) so I don’t think it’s the #lisp part of emacs I have a distaste for.
I’ll probably give it a serious go within the next week here and possibly report back, but I can’t imagine an emacs clone without #magit#orgroam and ChatGPT-shell will really ever become my daily driver 🙃
