Re: cloning lua state

[Tim Hill <drtimhill@...>]

Well there is no Lua API to do this and a full clone would be immensely difficult. You would have to deep copy the registry, and in the process would hit things that are not easily copied such as user data and threads. So in practice this could only work if the source Lua state had no userdata and no threads. You would also have to handle issues with loaded libraries and special case some of the standard libraries.
