Scripting

This page is about using scripting technologies to provide the Pod control functions instead of native DLLs.

Advantages of scripting:

Scripts are platform independent by nature.
Scripts can be run in a sandbox, thus malicious or bugged scripts can do less harm to the host system.
Easier and faster development. Thus more developers to develop in scripting languages?

Disadvantages of scripting:

By default, a script is plain text. Since this is a programming contest, we need to find a way of hiding the code between different developers. Otherwise cheating would be too easy.

Candidates

List of scripting language candidates.

Common requirements:

Must be embeddable in C/C++.
Several instances of the same script must be able to run at once. Requires a mechanism to switch contexts.
It should be possible to run the script in a sandbox environment, with only minimum library support.
There must be a mechanism to compile or obfuscate scripts so they're don't need to be distributed in plain text.

Javascript

To be embedded via the Google V8 Javascript engine:

Lua

http://www.lua.org/manual/5.1/manual.html#3
http://www.ibm.com/developerworks/linux/library/l-embed-lua/
http://heavycoder.com/tutorials/lua_embed.php
http://code.google.com/p/lua-vec/ -- A Lua mod for fast vectors

Meets requirements?

Embeddable: OK.
Context management: OK. Different independent Lua states can be instantiated with lua_State *L = lua_open();
Sandbox: OK. Open all or only part of the standard libs.

Distribution: OK. Lua scripts can be compiled to byte code.

Python

Meets requirements?

Embeddable: OK.
Context management? To check. Different "Threads" can be craeted for Python interpreter.
Sandbox?
Distribution? Python scripts can be compiled.
