Please meet: Lua

Originally published at Fiberglass flowers. You can comment here or there.

Lua recently became very popular. I encountered Lua scripting in several applications including popular games, I believe it’s used in even more then Wikipedia says.

It’s extremely simple:

• 6 data types (that’s counting “nul” and “function”),
• no C++-style OOP out-of-box (but you can program one, he-he),
• 400K of pure-C code

but is loaded with in-fashion features like

• first-class functions,
• closures,
• coroutines…
• again, Wikipedia is the best.

The only metaprogramming tutorial (with a ready code to implement virtual methods) is “Programming in Lua” book. Still, I don’t see a code to implement ad-hoc polymorphism… Maybe it’s a reason for another post
