Lua is a very nice and easy to learn scripting language specifically designed to be embedable and able to represent complex data.
- Clean syntax
- Simple yet extremely powerful and extensible datastructure, the tables, that can be used as hashtables, vectors, arrays, lists, namespaces, objects, ...
- Easily embedable into existing projects
- Very fast
- Can be compiled to bytecode(actaully it always is, but the bytecode cna be dumped to a file for latter reuse)
- Many other nifty things ;)
Lua is heavily used by some roguelikes, like ToME, where a good part of the engine is in Lua and the game itself will be completly in Lua in the next version, and the [[H-World] engine.
