LabLua consists of people from a wide range of backgrounds, including PhD candidates, professors and alumni who are the developers and maintainers of projects that are used by the Lua community at large.

What is Lua?

Lua is a powerful, efficient, lightweight, embeddable scripting language. It supports procedural programming, object-oriented programming, functional programming, data-driven programming, and data description.

Lua has been used in many industrial applications (e.g., Adobe's Photoshop Lightroom), with an emphasis on embedded systems (e.g., the Ginga middleware for digital TV in Brazil) and games (e.g., World of Warcraft and Angry Birds). Several versions of Lua have been released and used in real applications since its creation in 1993.
