You don't have to know everything about a car to drive one, and you
don't need to know everything about Ruby to start programming with it.
Written for both experienced and new programmers alike, Learning Ruby is
a just-get-in-and-drive book — a hands-on tutorial that offers lots of
Ruby programs and lets you know how and why they work, just enough to
get you rolling down the road.
Interest in Ruby stems from the popularity of Rails, the web development
framework that's attracting new devotees and refugees from Java and
PHP. But there are plenty of other uses for this versatile language. The
best way to learn is to just try the code! You'll find examples on
nearly every page of this book that you can imitate and hack. Briefly,
this book:
* Outlines many of the most important features of Ruby
* Demonstrates how to use conditionals, and how to manipulate strings in Ruby. Includes a section on regular expressions
* Describes how to use operators, basic math, functions from the Math module, rational numbers, etc.
* Talks you through Ruby arrays, and demonstrates hashes in detail
* Explains how to process files with Ruby
* Discusses Ruby classes and modules (mixins) in detail, including a brief introduction to object-oriented programming (OOP)
* Introduces processing XML, the Tk toolkit, RubyGems, reflection, RDoc,
embedded Ruby, metaprogramming, exception handling, and other topics
* Acquaints you with some of the essentials of Rails, and includes a short Rails tutorial.
Each chapter concludes with a set of review questions, and appendices
provide you with a glossary of terms related to Ruby programming, plus
reference material from the book in one convenient location. If you want
to take Ruby out for a drive, Learning Ruby holds the keys.
