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 and global 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 and time formatting directories; Interactive Ruby (irb) and the Ruby debugger; and 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.

es war alles paletti,
aber diese neue Amazon Bewertung mit mindestens 20 Wörtern kostet zu viel Zeit, keine gute Idee!

HASH(0x8a3a0264) von 5 Sternen Handy Reference and Guide 9. August 2007
Von Scott Schram - Veröffentlicht auf Amazon.com
Format: Taschenbuch
This book is a handy reference and guide to the Ruby programming language. Small and lightweight, it would be at home in a laptop bag.

I program in several languages (lately: Ruby, Java, XHTML, CSS, JavaScript). A quick reference book like this is helpful when switching contexts, reminding me of the syntax or method call that has slipped my mind.

The explanations and examples concisely illustrate the language concepts. Tables list (often all of) things like pre-defined variables, global constants, etc.

An experienced programmer could learn the important basics of Ruby in a quick scan of the first 60 pages. However, I would still recommend reading one of the thorough tutorial books to get an in-depth understanding of some of the more unique Ruby techniques.

In addition to the items covered in the product description, the book includes:

* The most commonly used areas of the File and IO classes.

* A glossary of Ruby specific terms.

* RDoc, the utility for extracting documentation embedded in comments in Ruby source, and the basics of formatting your comments for RDoc.

* A thorough 20 page index including all of the special characters (punctuation) in use in Ruby. Very handy when trying to read someone else's code.

* Many links to Ruby resources on the web.

Note that the Amazon book description should read "sprintf and time formatting *directives*". That is, the special character combination for formatting strings and the output of time.

I'd feel much better about this guide if it were up to date with the latest version of Ruby or at least the latest, most commonly used version.

HASH(0x8a3a2ce4) von 5 Sternen Handy reference for the experienced Ruby programmer 31. August 2007
Von calvinnme - Veröffentlicht auf Amazon.com
Format: Taschenbuch
You probably could learn Ruby from this handy little pocket guide, but I wouldn't advise trying it. The examples are much too short and sweet to really do a good job of it. For the experienced Ruby programmer, though, it is a great reference on all aspects of the language. It even has introductory material on how to get started running Ruby, plus some bonus material at the end on RubyGems, Rake, and a listing of additional Ruby resources - some online and some that are books. RubyGems is a package utility for Ruby that installs Ruby software packages and keeps them up to date. It is even easier to use than tools like the Unix/Linux tar utility or Java's jar utility. Rake is a build tool that helps you build, compile, or otherwise process files, sometimes large numbers of them. Rake is similar to "make" and Apache ant, but is written in Ruby. Rails operations use Rake frequently.

The only negative thing I can say is that it seems like the book was hastily edited. I haven't seen any errors in the technical directions yet, but I have caught more than a few grammar errors and odd repetitions in the regular text that might have you scratching your head and wondering what the author meant. The following is the table of contents:

HASH(0x8a3a29d8) von 5 Sternen Very Useful Resource 21. Juli 2012
Von Jeremy Lee James - Veröffentlicht auf Amazon.com
Format: Kindle Edition Verifizierter Kauf
I use RUBY POCKET REFERENCE as an alternative to Google when I'm on my MacBook Air. I load the reference up on the Kindle app on my iPad and use the search function. Instead of having to wade through a hit-or-miss results page on a search engine, I get to maintain my context in MacVim on the Air, and reference the bit of syntax I was looking for on the iPad's screen, adjacent.

The team behind RUBY POCKET REFERENCE did a great job of distilling what you need to know about Ruby, while still presenting the information with enough context and guidance that it doesn't read like a mere concordance or index.

This book is a great way to quickly learn the basics of Ruby, and when used in the way I describe above, really shines.
