Editorial Reviews

From Barnes & Noble
The Barnes & Noble Review
Ruby Gems offers Ruby users an extensive collection of software solutions, together with consistent infrastructure for packaging and distributing them. Read David Berube's Practical Ruby Gems, and you'll become a far more effective Ruby (and Rails) programmer, capable of leveraging the work of the broader Ruby community.

Berube presents example-rich introductions to 34 of today's most impressive Gems. For instance: Camping, the elegant, superlightweight web application "microframework." And cmdparse for writing command toolkits. And erubis, for leveraging Ruby's full power to output HTML. And solutions for everything from validating credit cards to accelerating Rails applications, processing RSS feeds to using CAPTCHA to resist Spam.

Along the way, you'll learn how to create, package, and distribute your own Gems, share Gems between your own projects, handle dependencies and cross-platform issues, and more. Maybe Berube's next edition will contain a Gem of yours! Bill Camarda, from the June 2007 Read Only

    A reviewer

    Practical Ruby Gems, by David Berube (APress) digs into Rubygems ¿ the Ruby package management system. David presents a quick overview of Rubygems and its usage, then offers an overview of 29 popular gems, and finally shows you how to roll your own. Overall, this is a solid book. The writing is almost alarmingly to the point ¿ think O¿Reilly Pocket Reference style, but it does cover the material reasonably well. There is a pleasant variety in the gems presented, and I saw a few that I wasn¿t aware of (like FastCSV) which will definitely be useful to me. Each gem is presented with a short application that carefully balances meatiness against ease of comprehension. I¿m happy to report that Practical Ruby Gems is fairly well indexed. Some of the more complex gems (like ActiveRecord, FxRuby and Ruby on Rails) are given a very thin treatment, and I think that¿s fair enough, given the format of the book. ActiveRecord, let alone Rails, is large enough to have its own book. Other than that, my only complaint lies in the amateurish page layout. The transition from prose to sample code is delimited with only a change of font, and sample output is separated from code with a simple horizontal rule. This means that my eye must hunt and peck through the page when I¿m skipping around, looking for that particular line of sample code that I need. I would recommend this book to anyone looking for a high level overview of what¿s out there in the way of free Ruby libraries. I will also probably refer to the book if and when I roll my own gems.
