This tag is used for questions about the Lua programming language.

From Lua's About page:

What is Lua?

Lua is a powerful, fast, lightweight, embeddable scripting language.

Lua combines simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, runs by interpreting bytecode for a register-based virtual machine, and has automatic memory management with incremental garbage collection, making it ideal for configuration, scripting, and rapid prototyping.

The official implementation of Lua is written in ANSI C, but a list of several other implementations can be found on the Lua Users Wiki page on Lua Implementations.

The current official version of Lua is 5.2. The previous version (5.1) is available in the version history on the official site.

Please note that the official name of this programming language is Lua (a Portuguese word for Earth's moon). It is not an acronym -- it is not spelled LUA.
