You need surprisingly little in the way of computer resources to learn and use Lua. This book focuses on Windows and Unix-like (including Linux) systems, but any operating system that supports a command shell should be suitable. You'll need a text editor to prepare and save Lua scripts.
If you choose to extend Lua with libraries written in a programming language like C, you'll need a suitable software development kit. Many of these kits are freely available on the Internet but, unlike Lua, they can consume prodigious amounts of disk space and memory.
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---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.
This Second Edition updates the text to Lua 5.1 and brings substantial new material, including numerous new examples, a detailed explanation of the new module system, and two new chapters centered on multiple states and garbage collection.
If you play World of Warcraft, chances are you know what Deadly Boss Mods is: it's the most widely downloaded modification available for World of Warcraft, considered required software for many professional raid guilds, and arguably the most popular modern video game mod in history.
Paul Emmerich, the author of Deadly Boss Mods, will take you from novice to elite with his approachable, up-to-date guide to building add-ons for the most popular video game in history. Using the powerful Lua scripting language and XML, you'll learn how to build and update powerful mods that can fundamentally remake your World of Warcraft experience and introduce you to the field of professional software development.
Beginning Lua with World of Warcraft Add-ons teaches you the essentials of Lua and XML using exciting code examples that you can run and apply immediately. You'll gain competence in Lua specifics like tables and metatables and the imperative nature of Lua as a scripting language. More advanced techniques like file persistence, error handling, and script debugging are made clear as you learn everything within the familiar, exciting context of making tools that work in Azeroth.
You'll not only learn all about the World of Warcraft application programming interface and programming, and gain coding skills that will make all your online friends think you're a coding god, but also gain hands-on Lua scripting experience that could translate into an exciting job in the video game industry!
What you’ll learn
This book is for World of Warcraft players, developers, and mod makers who want to learn how to program add-ons in Lua and XML, either to learn Lua or to improve their game experience. Working coders who don't know Lua and want to learn about this exciting, popular scripting language will also benefit.
The advanced material in this book will also be useful to those with World of Warcraft addon programming experience, so prior programming experience is an advantage, but not a requirement.
