Practical Ruby Projects: Ideas for the Eclectic Programmer

by Topher Cyll and Christopher Cyll

Book Overview

Revitalized by Ruby on Rails, the Ruby language continues to grow in popularity. Books like this are necessary to fill the demand. Here is a classic of its kind; required reading for Ruby programmers who have already mastered the basics and want to learn higher level techniques. Practical Ruby Projects presents nine diverse projects that will teach new and innovative techniques in a learn-by-example fashion. These projects include a turn-based...

Easy Read

This is one of the rare technical books, that's actually quite fun to read. Additionally, all except the last two chapters can be read out of turn. I think this is an excellent book. Take the time and get excited by taking a fresh look at ruby.

Feet first and freewheeling

The hands-on style of this book is contagious; you'll find yourself really wanting to jump in and try out the code samples. The source is available on Topher's site, but the simplicity and sense of immediacy are such that you may want to just start typing it in yourself. In a few minutes, you're making music or creating a game.

A great seed for projects!

This is a great ruby book for those new to the language, or for those who already know a good deal of ruby but wouldn't mind learning how to do some cool quirky things with ruby, like programmatically compose and play midi. This book will not walk you through how to use ruby if you are new to the language -- but their are plenty of other books (and online references) that can do the real introductory teaching. Working through some of the projects in this book *will* help you really get comfortable with ruby, by putting it to practice in non-boilerplate ways. If you have more experience with Ruby, this book is still compelling. It walks through some nonstandard projects -- interesting projects on their own, and certainly the sort of projects that will get your mind working, and have you looking at the problem and the language in a new light. Throughout, care is taken with the writing -- the text isn't a boring technical manual, but is compelling and interesting, while packing in a lot of technical detail!

Finally a book for experienced Ruby developers

The past few years have seen the English-language Ruby book market explode. Before the phenomenal success of Rails it was perfectly possible to own every available title (and not use much storage space), but now that would be quite a challenge and lead to considerable redundancy. Having worked my way through quite a few Rails books of late, reading Practical Ruby Projects--a Ruby book that doesn't even mention web frameworks--was both a pleasant diversion and a highly illuminating experience. Like the last volume I reviewed (Pro JavaScript Design Patterns), this book is unabashedly aimed at experienced programmers. There's a brief paragraph on "getting set up", but no detailed guide to obtaining the tools. Instead we dive right in to a sequence of projects that includes: making music (dipping into calling C code from ruby), animation, simulation, building a strategy game (and adding a RubyCocoa frontend), genetic algorithms, and even implementing lisp and parsers. Once again the "apress roadmap," a diagram intended to show how the skillsets in their different volumes build on one another, is misleading pitching this between "Beginning Ruby" and other volumes I've reviewed like Practical Ruby for System Administration and Pro Active Record. Don't believe it. Though there's little overlap in the material, this is a more advanced volume than either of those and readers should be prepared. The pace of the book is measured and Topher Cyll does a good job of gradually building up the projects a step at a time. Along the way a variety of practices are demonstrated with many methods stubbed out for demonstration purposes before being filled in when they are needed, and considerable time spent on decoupling code. That latter piece is particularly in evidence in the chapters on building a turn-based strategy game and then developing a RubyCocoa front-end. Despite careful design early on further refactoring is needed to make it easy to apply the front-end and that process is carefully worked through. Most of the book makes some use of existing libraries. The initial lisp chapter uses the sexp library and the subsequent section on writing a parse relies on rparsec. For the most part, however, use of the libraries is kept to a minimum, allowing for fairly self-contained code. Unit testing is largely ignored until the last chapter, where the need for tests when constructing a grammar/parser is explained and a test-first development model is encouraged. That works well to demonstrate the power of tests for complex (and often brittle) code. This is not a book designed for public transport reading. Working through chapters on the bus I frequently found myself wanting to reach for my laptop to get a better grasp of how a piece of code worked. While the explanation is generally very good, with material of this complexity there is nothing like running the code and tweaking it to make sure you've understood exactly what each transformation does. It's a book to ta

Best Ruby Book Since "The Ruby Way"

Most Ruby books milk newbies jumping on the bandwagon for cash. This is a book for experienced Ruby programmers who want to be awesome Ruby programmers. The book of the book is all about parsing and shows you how to implement Lisp in Ruby; the first project is a compact, simple, powerful system for creating music in real time in Ruby. I'm using it to drive Propellerhead Reason from the command line and I'm on page 25. This is an absolutely excellent book. The best Ruby book I've seen in years. The only Ruby book I'd recommend to experts. This is the bomb book.
