Great. So, what's the extension language? Rust is utterly inadequate to be a scripting language (if you have to recompile the text editor to reconfigure it, that's a non-starter).
VimScript sucks, but it's better than literally nothing. Emacs Lisp is weird, but powerful. Python is great and everyone knows it. Lua is small, simple, blindingly fast, and literally designed to be embedded in compiled projects.
Why is there no mention of extensions or extensibility?
While we're on the topic, if the perfect editor existed, what extension language do you think it would use?
I really like the way kakoune (https://github.com/mawww/kakoune) handles it, the editor doesn't have any scripting as such, it has an "API" in the form of pipes and environment variables that can be used by shell scripts or tools written in any language. Unix is the IDE.
I just could never get my head around the key bindings with kak.
