Programming Ruby 1.9 & 2.0 The Pragmatic Programmers’ Guide 4th Edition

Ruby is the fastest growing and most exciting dynamic language out there. If you need to get working programs delivered fast, you should add Ruby to your toolbox. This book is the only complete reference for both Ruby 1.9 and Ruby 2.0, the very latest version of Ruby. 2013 marks the 20th anniversary of the Ruby language. We’re proud that throughout its history, we’ve continued to cover the latest version of Ruby. Would you like to go from first idea to working code much, much faster? Do you currently spend more time satisfying the compiler instead of your clients or end users? Are you frustrated with demanding languages that seem to get in your way, instead of getting the work done? Are you using Rails, and want to dig deeper into the underlying Ruby language? If so, then we’ve got a language and book for you! Ruby is a fully object-oriented language, much like the classic object-oriented language, Smalltalk. Like Smalltalk, it is dynamically typed (as opposed to Java or C++), but unlike Smalltalk, Ruby features the same conveniences found in modern scripting languages such as Perl and Python. The combination of the power of a pure object-oriented language with the convenience of a scripting language makes Ruby a favorite tool of intelligent, forward-thinking programmers. The Pickaxe contains four major sections: An acclaimed tutorial on using Ruby. The definitive reference to the language. Complete documentation of all built-in classes, modules, and methods. Complete descriptions of all 97 standard libraries. This is the reference manual for Ruby, including a description of all the standard library modules, a complete reference to all built-in classes and modules (including all the new and changed methods introduced by Ruby 1.9, 1.9.2, 1.9.3, and 2.0). It also includes all the new and changed syntax and semantics introduced since Ruby 1.8.
