Amit Upadhyay writes "KDE's award winning integrated development environment KDevelop, has integrated support for Ruby, an excellent and easy to use object oriented scrpting language. If you are looking for a good programming tool for quickly developing a professional one off application, Ruby (with KDE bindings) maybe just the thing for you. There is a quick tutorial and an online book to get you started. You may also want to read a quite informative comparison of Python with Ruby. If you are web developer or write enterprise applications with JAVA etc, take a look at Ruby on Rails(api), they have a nice blog too. KDevelop provides a GUI builder and Debugger for rapid application development(RAD) with Ruby, which is getting better. There is a nice tutorial on using KDE libraries with Ruby. And if you have lots of code in C/C++, extending Ruby to use them is easy.

anonymous writes "The Free Software community is on a quest for the next generation development environment. Is it .Net, is it Java? Many (including Havoc) are quick to dismiss some of the gems invented by the Free Software community itself. Yes, Ruby is an incredibly consistent and clean language designed specifically to incorporate many of the best features and ideas of predecessors. Absolutely everything in Ruby is an object and practically everything can be redefined or extended on the fly. The effects and resulting power of such flexibility can be quite astounding to those who have adapted to contemporary language limitations. Now, the Ruby environment has been seamlessly integrated into KDE through Korundum, meaning that well-integrated and first-class desktop citizens for Linux can be sketched and developed in an extremely short time. Caveat: No explicit compilation is required and programming seems so easy it feels like cheating."

DJSpray writes "I've written a review of three books about the Ruby programming language, available on my weblog here. The three books are Yukihiro Matsumoto's Ruby in a Nutshell from O'Reilly, Hal Fulton's The Ruby Way (Sams), and Programming Ruby: The Pragmatic Programmer's Guide by Dave Thomas and Andrew Hunt (Addison-Wesley). Note that the third book is available online here for those who prefer that sort of thing. Executive summary: while I have found several of the other O'Reilly Nutshell series books to be excellent, this one is riddled with errors, confusing writing, and omissions, and does not live up to O'Reilly's usual standards. Fulton's book is filled with good cookbook examples and well-written explanatory material, as well as solid tutorial examples, but it is not structured as a reference. The Pragmatic Programmer's book works well as a reference and covers language features in increasing depth, but with fewer examples. Ruby beginners may find that the latter two books actually complement each other nicely, while I can't recommend this edition of the Nutshell book at all."

While Ruby isn't new, it's one scripting-and-everything else language which has yet to break out (in the U.S. at least) the way Perl and Python have. Chromatic may help buck that non-trend -- he says that Ruby is one polished gem of a language, and below he introduces a book on Ruby that he compares in importance with the O'Reilly Camel book.

Programming Ruby author David Thomasand Andrew Hunt pages 564 publisher Addison-Wesley rating 9 reviewer chromatic ISBN 0-201-71089-7 summary A no-nonsense, clear guide that's as clean and usable as Ruby itself.

The Scoop Ruby is a growing language that combines the power and conciseness of Perl with the Smalltalk object model. Though popular in Japan, it hasn't reached its potential in English speaking countries, lacking appropriate documentation. Enter Dave Thomas and Andy Hunt. On the heels of The Pragmatic Programmer, they've produced the Ruby equivalent of Perl's Camel. What's to Like? Programming Ruby starts with a general language overview. A dozen short and sweet chapters form this tutorial. Readers with no programming background won't feel too out of place, though they will need to be comfortable with terminology explained once and used throughout the rest of the book. Topics range from language basics to multithreading and using the debugger. Rather than starting from syntax rules, the authors introduce concepts as their context dictates. There is some conceptual overlap between chapters, but this approach is preferable to discussing one topic at a time, referring briefly to future chapters.

The next section shows how to connect Ruby to other languages and tools. Besides information on Ruby modules and the command line, chapters include CGI programming, Ruby GUI programming with Tk, and automating Windows. The chapter on embedding Ruby in C is short but comprehensive. Within the 200 pages of these two sections, experienced programmers will have learned enough Ruby to be quite productive.

Section three expands further on the core language. Though covering the same areas as the tutorial, these chapters delve into the gory details. (As gory as Ruby gets, which is to say, surprisingly little spit and bailing wire.) Thomas and Hunt write with the authority of language designers producing a standard reference. Chapter 19, Classes and Objects, particularly stands out. It describes Ruby's simple object model, using a handful of well-chosen examples and clean diagrams to punctuate the point.

The final section takes up nearly half of the book. This library reference lists Ruby's built-in and common classes and objects. Each class has a description, a named parent, and a list of mixins and class and instance methods where appropriate. Modules fare similarly. Most explanations include common usage examples.

Four appendices and an impressive index round things out.

What's to Consider? Ruby itself makes a fine starting language. To get the most benefit from the book, it's handy to have experience with OO programming and a similar scripting language. (Python and Perl hackers will have little trouble, Smalltalk coders will feel right at home, and Java and C++ fans will do well.) Beginning programmers won't have their hands held for very long.

A handful of advanced concepts are mentioned but not explained. This is only a minor gripe -- techniques like runtime code generation are beyond the scope of the average hacker's needs. The flexibility of Ruby's object model and the loose distinction between compile-time and run-time obviate the need for much of this trickery anyhow.

Some might find the class reference section slightly hard on the eyes. The repeated horizontal lines are visually distracting -- indentation would improve readability. On the positive side, the class, library, and module sections are arranged alphabetically, with a tabbed margins to improve navigation.

The Summary This attractive tome ought to be on the desk of any serious Ruby programmer -- and Ruby itself deserves consideration as a clean and powerful development language. Aimed at moderately experienced programmers, Programming Ruby is a great introduction and a handy reference. Read it online here! Table of Contents
