Luerl - an implementation of Lua in Erlang

An experimental implementation of Lua 5.2 written solely in pure Erlang.

Some things which are known not to be implemented or work properly:

- label and goto

- tail-call optimisation in return

- only limited standard libraries

- proper handling of __metatable

- ...

There are some simple interface functions in luerl.erl:

- luerl:eval(String) evaluates the Lua code in String. Returns the return values of the evaluation.

- luerl:dofile(FileName) reads in and runs the Lua code in the file and returns the values of the evaluation. Equivalent to doing luerl:eval("dofile('FileName')").

and some more basic interface functions:

- luerl:ps(String) parses the string and returns a chunk code.

- luerl:init() initialises the system and returns an initial state.

- luerl:do(String, State) evaluates the chunk in String with the current state and returns the values and a new state.

- luerl:gc(State) runs the (experimental) garbage collector on a state and returns the new state.

N.B. This interface is subject to change!
