Rings: Multiple Lua States

Rings
Multiple Lua States

## Overview

Rings is a library which provides a way to create new Lua states from within Lua. It also offers a simple way to communicate between the creator (master) and the created (slave) states.

Rings is free software and uses the same license as Lua 5.1.

## Status

Rings version 1.2.3 is now available for download.

## Download

Rings can be downloaded in source code from its Github page.

## History

Version 1.2.3 [20/Oct/2009]
  - Fixing an old reference to "arg" instead of {...} - Reported by MFarm
Version 1.2.2 [30/Jun/2008]
  - Fixed a stack handling issue (bug report and patch by Shmuel Zeigerman)
Version 1.2.1 [8/May/2008]
  - Fixed bug [#2074] - Rings uses the deprecated function luaL_openlib (patch by Ignacio Burgueño)
Version 1.2 [18/Feb/2008]
  - `rings.new` now takes an optional environment to be used by `remotedostring`. If the environment is nil, it defaults to `_M or _G`.
  - Fixed a bug with interaction of rings and coroutines, rings was assuming a 1:1 mapping between lua_States and rings master and slave states, which is not true when coroutines/threads are involved. (bug found by Ignacio Burgueño)
Version 1.1 [11/Jun/2007]
  Adapted to work with Lua 5.1.
Version 1.0 [10/Mar/2006]
  First public version, works with Lua 5.0.
