OverviewCode Generation in Action, CGiA to its friends, is presented in two parts. The first part is four chapters, and covers a code generation case-study, the basic principles of code generation, including the different types of code generation strategies together with reasons why you would or would not use each strategy. The book's chosen toolset for building generators is presented next, and then some walk-through examples of building simple generators wraps up the first part.
The second part is a kind of a cross between a cookbook and a list of engineering solutions. There are nine chapters with the breadth of solutions covered being quite impressive, covering the gamut of generation of user interfaces, documentation, unit tests and data access code. Each chapter presents a couple of solutions within its topic area, often for different technologies within that topic. For example, the user interface chapter covers the generation of Java ServerPages, Swing dialog boxes and then Microsoft MFC dialog boxes. No favouritism here!
What's To LikeThere's a lot to like with this book. The writing is very clear and of good prose. I found the introduction to be very compelling, and I felt completely drawn in by the opening case-study. The four chapters of part one are a concise case for code generation, and would be very useful information to help persuade co-workers and management of the positive risk/benefit ratio with trying code-generation on a live project.
It would be impossible to try enough of any solution from part two in a time-frame short enough to make this review useful, but in the solutions that match my areas of knowledge, I found myself admiring Herrington's straight-forward and pragmatic approach.
What's To ConsiderThere are two aspects of this book that I want to flag. One of these aspects, some will love and others will hate, and that is the choice of generator language for CGiA. The author has chosen to use Ruby as his working language. This is an interesting choice. Ruby is certainly a language that is inspiring a lot of admiration these days (in fact, it's hard to get Dave Thomas to stop talking about it :-), but with the majority of the code-generation examples being for Java-related technologies, I wonder why Java was not selected instead.
I also found myself wondering about the lack of discussion of how to integrate these Ruby tools into a typical Java build process. Many developers I know use ant to bring automation and consistency to their builds, yet the book doesn't mention this. (JRuby anyone?) Certainly something to consider for the second edition or future code-generation authors.Summary
This is a masterful tome that inspires and delights, although the two issues raised above did cost it a perfect score of ten.
