| There may be no better way to learn how to program than by
dissecting real, representative examples written in your
language of choice. Ruby by Example analyzes a series of
Ruby scripts, examining how the code works, explaining the
concepts it illustrates, and showing how to modify it to
suit your needs. Baird's examples demonstrate key features
of the language (such as inheritance, encapsulation,
higher-order functions, and recursion), while simultaneously
solving difficult problems (such as validating XML, creating
a bilingual program, and creating command-line interfaces).
Each chapter builds upon the previous, and each key concept
is highlighted in the margin to make it easier for you to
navigate the book.
You'll learn how to:
Use the interactive Ruby shell (irb) to learn key features
of the language
Extend Ruby using RubyGems, the Ruby package manager
Create numerical utilities, as well as utilities that
process and analyze HTML/XML
Implement purely functional and metaprogramming techniques
to save time and effort
Optimize, profile, and test your code to make sure that it
not only does its job, but does it well
Create web applications using Rails
Ruby is the fastest growing programming language today, and
for good reason: Its elegant syntax and readable code make
for prolific and happy programmers. But it can be difficult
to understand and implement without a little help. Ruby by
Example shows you how to take advantage of Ruby as you
explore Ruby's fundamental concepts in action.
