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. Learn about the new parameter passing rules, local variable
scoping in blocks, fibers, and the new block declaration syntax,
among other exciting new features. About Ruby 2.0 Ruby 2.0 is a
minor update to Ruby 1.9, unlike the more major updates from Ruby
1.8 to Ruby 1.9. The 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. There are a number of additions to
the standard library, including: * @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.
You'll also find that Ruby 2 is faster, and has memory management
improvements that make it more server-friendly. All told, there are
over 110 sections of the book that have been flagged and
cross-linked to indicate 2.0 content. What You Need * This book
assumes you have a basic understanding of object-oriented
programming. * 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.
