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.
nThis book is the only complete reference for both Ruby 1.9 and Ruby 2.0, the very latest version of Ruby.
n2013 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.
nWould 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!
nRuby 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.
nThe 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.
nThe Pickaxe contains four major sections:
n n 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. n nThis 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. Learn about the new parameter passing rules, local variable scoping in blocks, fibers, and the new block declaration syntax, among other exciting new features.
nAbout Ruby 2.0
nRuby 2.0 is a minor update to Ruby 1.9, unlike the more major updates from Ruby 1.8 to Ruby 1.9.
nThe 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.
nThere are a number of additions to the standard library, including:
n n @Enumerator::Lazy@, which adds support for lazy access to potentially infinite lists. * 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. n nYou'll also find that Ruby 2 is faster, and has memory management improvements that make it more server-friendly.
nAll told, there are over 110 sections of the book that have been flagged and cross-linked to indicate 2.0 content.
nWhat You Need
n n nThis book assumes you have a basic understanding of object-oriented programming.
n n nIn general, Ruby programmers tend to favor the the command line for running their code, and they tend to use text editors rather than IDEs.
n n nRuby runs on Windows, Linux, and Macs.
