If you need to get working programs delivered fast, you should add Ruby to your toolbox. \u003c\/p\u003e\u003cp\u003eThis book is the only complete reference for both Ruby 1.9 and Ruby 2.0, the very latest version of Ruby. \u003c\/p\u003e\u003cp\u003e2013 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.\u003c\/p\u003e\u003cp\u003eWould 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!\u003c\/p\u003e\u003cp\u003eRuby 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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eThe Pickaxe contains four major sections:\u003c\/p\u003e\u003cp\u003e\u003cb\u003e An acclaimed tutorial on using Ruby.\u003c\/b\u003e The definitive reference to the language.\u003cb\u003e Complete documentation of all built-in classes, modules, and methods.\u003c\/b\u003e Complete descriptions of all 97 standard libraries.\u003c\/p\u003e\u003cp\u003eThis is \u003ci\u003ethe\u003c\/i\u003e 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. Learn about the new parameter passing rules, local variable scoping in blocks, fibers, and the new block declaration syntax, among other exciting new features.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eAbout Ruby 2.0\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eRuby 2.0 is a minor update to Ruby 1.9, unlike the more major updates from Ruby 1.8 to Ruby 1.9.\u003c\/p\u003e\u003cp\u003eThe major language changes in Ruby 2.0 are the addition of keyword arguments and the change to use UTF-8 as the default source file encoding.\u003c\/p\u003e\u003cp\u003eThere are a number of additions to the standard library, including:\u003c\/p\u003e\u003cp\u003e\u003cb\u003e @Enumerator::Lazy@, which adds support for lazy access to potentially infinite lists.\u003c\/b\u003e Refinements allow you to encapsulate changes to third-party classes, and scope their application to individual source files, preventing your changes from polluting the global application.\u003c\/p\u003e\u003cp\u003eYou'll also find that Ruby 2 is faster, and has memory management improvements that make it more server-friendly.\u003c\/p\u003e\u003cp\u003eAll told, there are over 110 sections of the book that have been flagged and cross-linked to indicate 2.0 content.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eWhat You Need\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003e\u003cb\u003e This book assumes you have a basic understanding of object-oriented programming.\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003e In general, Ruby programmers tend to favor the the command line for running their code, and they tend to use text editors rather than IDEs.\u003c\/p\u003e\u003cp\u003e* Ruby runs on Windows, Linux, and Macs.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"Pragmatic Programmers, LLC, The","offers":[{"title":"Default Title","offer_id":47046759874800,"sku":"9781937785499","price":50.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781937785499_p0.jpg?v=1763662538","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781937785499","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
