This is my first review of a book. I am sorry if I am too harsh. But these are my thoughts about the book. Good or bad, I would like to congratulate Packt publishing for accepting the publication of a book about a moving target. Catalyst is all but stable, and things change from week to week.

On to my comments:

The first chapter is a concise introduction to MVC. Instead of describing the details on what this approach means, the author motivates the user for its need. No big definitions are given: just the needed to understand the Catalyst architecture. At the end, a small section discusses the Catalyst framework installation. I would not add that section to the end of the first chapter, but probably as an introduction to the second one. But there are just details.

After this quick presentation on the MVC design pattern, the author introduces the implementation of Views, Controllers and Models. This introduction is very soft, but enough to the reader to start understanding the basics of Catalyst. Sometimes the author tries to explain a little detail that will be expanded later without much success. If you have an idea of Catalyst you will be able to start writing your first application and exploring some new features of Catalyst.

The third chapter main purpose is to present a basic CRUD: Create, Read, Update, Delete application. It starts with the definition of the database model, exactly where the most audacious reader will be making questions. This makes it a good complement of the previous example. Follows some details on how to build a form using Catalyst::Controller::FormBuilder, and how to use this form for creation and updating of database records.

Format: Paperback
This is the first Catalyst-related book to be published, and I'm very happy of this as Catalyst is my platform of choice for web application development. Packt seems like a great publisher, as it provides books on very specific topics that otherwise might end up being uncovered by the printed media.

Catalyst is a killer Perl application, and brings MVC web development to a new level. The main other available frameworks (i.e. Rails) try to impose the framework authors' choices on the developer (i.e. which templating system to use, which database abstraction library to prefer, ...); Catalyst simply provides a basic structure, along with a wide range of different choices which play well with this basic structure. This approach greatly improves the developer's opportunities to create customized and high-quality software, but it also has a downside: newbies find it difficult to enter the Catalyst world, as they have to make choices they're not yet ready to make, and so they might tend to walk away from Catalyst, leaning towards a different framework. Jonathan Rockway's book attempts to solve this problem, providing a beginner's guide to Catalyst where all the relevant choices have already been made by the author. This book tells you: "there's more than one way to do things, and this is my way; follow it, and then you might decide to stick with it or make changes but, in the meanwhile, you will have learned Catalyst".

Catalyst - Accelerating Perl Web Application Development begins with an introduction to MVC concepts and with an overview of the Catalyst installation. The main focus of the book is, however, development of applications, from simple to more advanced ones which involve complex database operations and authentication.

Format: Paperback
Catalyst is a flexible and powerful framework for writing web-based applications in Perl. But with power and flexibility you'll always get a certain amount of complexity and on the occasions that I have looked at Catalyst for a project, the complexity has got the better of me and I've always turned to a less complex (and therefore less flexible and powerful) system. I knew that Catalyst was something that I should take the time to learn, but it always seemed like such a daunting task.

For that reason, I was really looking forward to reading this book. I'm the kind of person who learns best from reading a book and I hoped that with a few tube rides reading this book, coupled with a few practical sessions in front of the computer, I'd soon have Catalyst. I'm sorry to report that having read the book, Catalyst is almost as confusing to me now as it was before.

I don't think that much of the blame can be laid at the feet of the author. Jonathan Rockway is a member of the core Catalyst development team. I've read his blog and his contributions to various mailing lists. He obviously knows his stuff. I think he's been badly let down by his editors.

The problems are at two levels. Firstly there are many typos and errors that should have been picked up at the copy-editing stage, and secondly (and more importantly) I don't think that enough thought has been put into the organisation of the book.

Let's start by looking at the typos. The problems start before the book really gets going. On the "About the Reviewers" page, each of the two reviewers gets a paragraph to say thank you to various people. For the first reviewer this is typeset as a blockquote, for the other it's a normal paragraph.
