from my topic over at BoingBoing's BBS[bbs.boingboing.net]:

wait, what the heck?

Civilization V, like Civilization IV before it, uses a Lua interpreter to load information into the game, to build, and execute AI decision trees, and to execute routines. the diplomacy system? controlled by a .Lua file. the menu system? controlled by Lua. this allowed development of the game to occur very quickly in a collaborative setting without having to constantly build and deploy new versions of the game -- a Lua file is a plain-text file, easily shared.
Lua interfaces are not exactly uncommon. It's a very powerful scripting language, one that open source projects like Minetest use to enable users to create and distribute modifications. An entire game-making engine, LOVE2D, is built on it.
Lua is somewhere between Javascript and Python in terms of ubiquity, ease of development, and features. Created and maintained by a team at the catholic university PUC-Rio, Lua has been around for as long as the World Wide Web. It’s probably older than your children, and definitely older than your car. Like other programming languages, it routinely gets extended with newer updates and new features. Not all Lua functions are always integrated into games; some games only expose a narrow set of commands and data structures to a Lua API - reserving the real calculations for the meatier and faster native program binary.

Interpreted languages like Lua can be performant, but not nearly as fast in executing instructions as native programs. Enter the JIT. Just-in-Time compilers/interpreters convert script into machine language, making the exact same script execute dozens if not hundreds of times more quickly. JITs sometimes omit or rewrite how functions work; some JITs keep variables in memory after a function is completed, for example.

This mod is a customized, Just-In-Time Lua interpreter/compiler.

Specifically, this mod is a pre-compiled binary of moonJIT 2.2.

What it does is compiles .Lua files into machine-compatible low-level programming code. It keeps this code in memory so it can be executed very quickly when the game executes any functions that require reading a Lua file. Since the game can call a Lua file multiple times per turn, this mod essentially reduces the file read-> cache -> interpretation cycle to 0 milliseconds by doing it instantly.

Since text files don't use that much space, the amount of additional RAM consumed is around 50 megabytes. That's two mp3 podcast files. Or less than a single minute of video. Your music-streaming tab of spotify or youtube consumes 200x more RAM than this mod does.
