Lua script engine from Emacs Lisp. This package is inspired by mruby-lua.

How to build

% make LUA_VERSION=5.2
# Default Lua version is 5.2. You need to specify if you use other than 5.2.

Sample Code

  if n <= 1 then
    return 1
  else
    return n * factorial(n - 1)
  end
end

ans = factorial(10)
")))
    (message "@@ %s" (lua-get-global state "ans"))))
