Lua is becoming the language of choice for anyone who needs a scripting language that is simple, efficient, extensible, portable, and free. Currently, Lua is being used in areas ranging from embedded systems to Web development and is widely spread in the game industry, where knowledge of Lua is an indisputable asset.

Programming in Lua is the official book about the language, giving a solid base for any programmer who wants to use Lua. Authored by Roberto Ierusalimschy, the chief architect of the language, it covers all aspects of Lua 5.0---from the basics to its API with C---explaining how to make good use of its features and giving numerous code examples. Programming in Lua is targeted at people with some programming background, but does not assume any prior knowledge about Lua or other scripting languages.

Roberto Ierusalimschy is an Associate Professor of Computer Science at PUC-Rio (the Pontifical Catholic University in Rio de Janeiro), where he works with programming-language design and implementation. He is the leading architect of the Lua programming language and the author of "Programming in Lua" (now in its second edition and translated to Chinese, Korean, German, and Japanese).

Roberto has a M.Sc. Degree (1986) and a D.Sc. Degree (1990) in Computer Science, both from PUC-Rio. He was a visiting researcher at the University of Waterloo, (Canada, 1991), ICSI (CA, USA, 1994), GMD (Germany, 1997), and at UIUC (IL, USA, 2001/2002). As a professor at PUC-Rio, Roberto was the advisor of several students that later became influential members of the Lua community. Lately he has been developing LPEG, a novel pattern-matching package for Lua.
