Ruby has been the star of this year's programming book market. With Rails and Ruby recipes, this book will set the standard for learning Ruby in a variety of programming environments. This cookbook is in the tradition of the highly successful Perl, Python, and Java cookbooks from O'Reilly. "Ruby Cookbook" covers all aspects of the language, from basics to more advanced issues, so any level programmer can learn by example and improve with their Ruby development skills. A large section is included on Ruby on Rails, the rapidly growing Web development framework. Furthermore, a variety of recipes cover everything else people are doing with the language including AJAX development with Ruby, developing GUIs, working with XML, building applications with Rake, Ruby for system administration, and writing extensions to Ruby.
