Are there any embedded languages that can be embedded into C# and actionscript?

Question

I'm looking for a embedded language that can be used to script common code between a server app written in C# and a client app written in Flash/Actionscript. It is important that the embedded language interpreter run natively in the environment it is embedded into. For example, it cannot load any external C libraries (i.e. python, neko).

Does such a thing exist for these two languages? Perhaps there is some minimal interpreter that could be easily ported to both?

Thanks!

Answer 1

I believe Javascript is the answer.

Here's some thoughts on calling Javascript from Actionscript and vice versa.

It would probably end up fairly ugly, but someone has successfully embedded Lua into Actionscript through Alchemy -- demo on Google Code. Pair that up with LuaInterface and you've got an embedded language on both sides. You'll find a couple more "JavaScript (or ActionScript in Flash)" implementations of Lua on the Lua Implementations page.

There's also Pair, an AS3 implementation of Python that looks a lot more stable than Lua-Alchemy. The .NET complement would be IronPython.

Haxe can output a .swf, which might suffice for your needs -- I'm not sure if two .swf files can communicate, I don't really use flash. The big downside with Haxe is no native .NET support, although it can support Neko or C++, both of which you would have to go out of your way to integrate with .NET.
