Re: Emacs <-> Lua bridge

Awesome!

Several years ago I compiled the Lua interpreter into Emacs and added functions for accessing each from the other.

It was just fun experimental software and is not supported or actively developed and still has unresolved issues,

but might be of interest to you. This was before modules got added to Emacs.

You can check out the code here: https://github.com/mschuldt/luamacs
