Ruby/Python/LUA scripting within a C/C++ SDL game?

We are interested in developing some commercial games in
C/C++ using SDL, but
are interested in keeping some of the AI and game logic in a
higher-level
scripting language.

Anyone have any experience with using a built-in interpreter
using Python, Ruby,
or LUA to write a good portion of your higher-level game
logic?

I have seen PyGame and Ruby/SDL but these are really geared
for writing the
entire game in Python or Ruby, but I am only interested in
scripting parts of it.

Thanks!

http://boost.org/ has a
module called Boost.Python that allows the use of Python
scripting in a C++ application.  LUA might be better to use,
however.

You are right about that.

One other engine you might look into is http://Panda3d.org .  It
doesn't use SDL
but has been ported to several platforms.  It uses Python
and/or C++ as its
scripting language.

shows you how to embed the python interpreter into
you c++ application and easily execute scripts from within
your c++ app.

For Lua you should use LuaBind. It has a bit of a learning
curve but 
works very well. Keep in mind that Lua was specifically
designed to be 
embedded, which is not the case with many other scripting
languages.

If you plan to use LUA in plain C (like we do), read that:

Surely there are other tutorials, but I found that one to be
really  
simple.
