Roberto Ierusalimschy is an Associate Professor of Computer Science at PUC-Rio (the Pontifical Catholic University of 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 third edition and translated to Chinese, Korean, German, Japanese, and Russian).
Roberto has a M.Sc. Degree and a D.Sc. Degree in Computer Science, both from PUC-Rio. He was a visiting researcher at the University of Waterloo, ICSI, GMD, and UIUC, and a Tinker Professor at Stanford. As a professor at PUC-Rio, Roberto was the advisor of several students that later became influential members of the Lua community. Roberto is also a Distinguished ACM Speaker and a member of the IFIP Working Group on Language Design.
I recently got this book and read through it. Seeing there are no reviews here yet, I figured I better write one to give some an idea of what this book is about.
Note I'm no beginner to Lua. Over the last five years I have written thousands of lines of Lua and have done pretty advanced interfacing to the Lua C API (for custom modules), added LuaJIT and other customizations, etc. I really like the language; it's clean and simple, yet very versatile in it's details.
First, the book wasn't quite what I had expected. I was hoping it was full of little tricks and techniques of that I didn't already know. Although it's not in fact "Lua Snippets", it's "Lua programming Gems" after all..
A lot of it are what appears to be more of a case study for particular uses. Where the authors after having worked out some particular large or difficult problem wrote up sort of a post mortem on what worked for them; on how they solved it et al. Examples, there are articles on Lua for Game Programing, Lua versions of "Common Data structures" (STL C++ and C# types et al), and oddly even a Forth programming language in Lua, etc. A lot of which I found a bit abstract in context that was a lot about the problem and perhaps less of Lua as a language. Although all of which are great if something your looking for fits into one or more of these categories. You might find a solution to your problem and have it worth the price of book many times over.
My favorite article is the one of the less abstract called "Lua Performance Tips" which you can read officially online free here: [...Read more ›
