Looking for an embeddable scripting language for C++ with 64-bit support and Cross Platform

Question

I'm looking for a scripting language that works on 32-bit and 64-bit machines as well as on Windows and Linux. I will be embedding it into a C++ application so I prefer it to be natively written in C++ rather than C. I also would prefer the script to have thread/asynchronous support.

So far the languages that I have looked at are GameMonkey, Lua, and V8 JavaScript Engine. V8 JavaScript has the most appeal so far. I don't really want to use GameMonkey because AFAIK it doesn't support 64-bit addressing. Lua is written in C so I would probably use the C++ wrapper, but I really don't like mixing C and C++ code.

So are there some other alternatives that I could look at?

Answer 1

I personally prefer LUA over others. Maybe because it's used by WoW and I do my own tweaks for WoW addons. But I've seen many opinions that is good, even on SO.

Answer 2

Maybe Falcon, ChaiScript, IO or even AngelScript might match your requirements?

Answer 3

If you use qt you could use qtscript. Otherwise python might be a good idea.

Answer 4

I say Lua. It's ultraportable (It even runs under PalmOS, WindowsCE and DOS!), small (200-300k), fast and it is very easy to interface it with C/C++.

Also, Michael Pall makes amazing progress with his LUA JIT implementation. His current beta-4 supports x86 and x86_64 jitting and beats the crap out of almost every interpreter language I know: http://luajit.org/
