The Lua Language

Lua is a powerful, efficient, lightweight, embeddable scripting language. It supports procedural programming, object-oriented programming, functional programming, data-driven programming, and data description. Since its creation, in 1993, Lua has been used in many industrial applications (e.g., Adobe's Photoshop Lightroom), embedded systems (e.g., the Ginga middleware for digital TV in Brazil) and games (e.g., World of Warcraft and Angry Birds), and is currently the leading scripting language in games.

The Céu Language

Céu is a Structured Synchronous Reactive Programming language that aims to offer a higher-level and safer alternative to C. It extends classical structured programming with two main functionalities: event handling and synchronous, deterministic concurrency.

LabLua

LabLua is a research laboratory at the Catholic University of Rio de Janeiro (PUC-Rio), affiliated with its Computer Science Department. It is dedicated to research on programming languages, with emphasis on the Lua and Céu languages. LabLua was founded on May 2004 by Prof. Roberto Ierusalimschy, the chief architect of the Lua language.

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