Re: Getting lua to travel on .NET and the like

[Raymond Jacobs <raymondj@...>]

We looked briefly at XNua; notably it said coroutine support was untested and potentially broken;

http://www.xnua.com/xna_lua_docs_limitiations

coroutines are a major feature for us, so this was a bit disturbing, but we haven't confirmed it yet.

it also *seems* XNua hasn't been updated since 2007, which bodes well for any further work being done on it (should there be major features missing).

As for using .NET bytecode at runtime, I dunno if Silverlight or XNA allow that, might seem like a security risk *shrug*

Well, there is this: http://www.xnua.com/xna_lua_xnua

XNua takes C# code and translates it to .Net bytecode. This is fine,
but I would like to see a bit higher level abstract of this.

I've been digging into this lately, and it doesn't seem all that hard
to do a port of Lua to C#, where the lua execution loop is a C# loop.
This is a project I may start on soon, but haven't yet. So I'm
interested in hearing other people's thoughts about the whole issue.
