Although Ruby is an easy language to learn, in the heat of action you
may find that you can't remember the correct syntax for a conditional or
the name of a method. This handy pocket reference offers brief yet
clear explanations of Ruby's core components, from operators to reserved
words to data structures to method syntax, highlighting those key
features that you'll likely use every day when coding Ruby.
Whether you've come to Ruby because of the Rails web development
framework — Ruby's killer app — or simply because it's a relatively
clean, powerful and expressive language that's useful for a lot of
applications, the Ruby Pocket Reference is organized to help you find
what you need quickly. This book not only will get you up to speed on
how Ruby works, it provides you with a handy reference you can use
anywhere, anytime.
In this book, you find essential information on:
Reserved words, operators, comments, numbers, variables, ranges, and symbols
Predefined variables andglobal constants
Conditional statements, method use, classes, and modules (mixins)
Lists of methods from the Object, String, Array, and Hash classes and the Kernel module
sprintf andtime formatting directories
Interactive Ruby (irb) and the Ruby debugger
Ruby documentation
You also get information on the RubyGems package utility and Rake, a
build tool similar to make.. If you're using Ruby daily and just want
the facts-fast-Ruby Pocket Reference is your book.
