lusp
Scheme-like toy language implemented in Lua. Based on the amazing Peter Norvig's page "(How to Write a (Lisp) Interpreter (in Python))" http://www.norvig.com/lispy.html.
Compatible with Lua 5.1, 5.2, LuaJIT.
To run lusp-repl run:
lua "repl.lua"
or run Lua and type:
require('lusp'):repl()
Voila! Now you can start uber-lisp-hacking:)
