nlua - neovim as lua interpreter
https://github.com/mfussenegger/nlua
I had previously written about how to create a script that uses neovim and emulates the lua interpreter cli - now I finally got around to extract it into a dedicated project, with some instructions on how to use it with luarocks.
I meant more of how Emacs is really an interactive environment for a lisp interpreter. That is where you get all the “Emacs as an operating system” jokes from. NVim seems to be falling down the same rabbit hole of extensions and obscure commands except by way of Lua rather than Lisp.
