Art Martin Fowler Ebook


Sunday, June 2, 2019

It's only just over a year since I got my first ebook reader. Now I only buy paper books when I really have to. I wrote my last book thinking of it. Over the last few years, I've succumbed to an unfortunate addiction - that of writing books. Although after each book I seriously consider giving it up, I haven't yet. Buying an ebook from them allows you to freely download ebooks in epub, pdf, and MOBI formats. (MOBI is Kindle's format, you copy the book.

I needed to reconsider the motivation, often feeling that it needed to be reframed. The mechanics needed at least a detailed review, often a complete rewrite. I wasn't keeping detailed notes on this, but my feel is that for every relatively simple import of an old refactoring, there were two that required a complete rethink.

However there is another change, which in a way isn't that important, but is bound to get a lot of attention.

The examples are no longer in Java. When I choose a language for examples in my writing, I think primarily of the reader. I ask "what language will help the most readers understand the concepts in the book?

I picked Java because I felt the most people would be able to understand the code examples if they were written in Java. That was the case in , but how about in ? I considered using multiple languages, which would emphasize the language-neutral intent of the book.


But I felt that would be more confusing for the reader, better to use a single language so they can get used to a consistent form of expression. So which one would be the most approachable to readers? Such a language needed to be widely popular, among the top half a dozen in language popularity surveys. It really helps to have a C-based syntax, since most programmers would recognize the basic code structure. Given that, two stood out. One was Java, still widely used and easy to understand.

The Second Edition of "Refactoring"

But I went for the alternative: JavaScript. Choosing JavaScript was deeply ironic for me, as many readers may know, I'm not a fan of it. It has too many awkward edge cases and clunky idioms. ECMAScript ES6 introduced a rather good class model, which makes many object-oriented refactorings much easier to express, but still has annoying holes that are built into the fabric of the language from its earliest days. But the compelling reason for choosing it over Java is that isn't wholly centered on classes.

There are top-level functions, and use of first-class functions is common.

This makes it much easier to show refactoring out of the context of classes. A Web-First Book The world-wide web has made an enourmous impact on our society, particularly affecting how we gather information. When I wrote the first edition, most of the knowledge about software development was transferred through print. Now I gather most of my information online.

This has presented a challenge for authors like myself, is there still a role for books, and what should they look like? I believe there still is role for books like this, but they need to change. The value of a book is a large body of knowledge, put together in a cohesive fashion.

In writing this book I need to gather together lots of refactorings, and organize them in a consistent and integrated manner. But that integrated whole is an abstract literary work that, while traditionally represented by a paper book, need not be in the future. Most of the book industry still sees the paper book as the primary representation, and while we've enthusiastically adopted ebooks, these are just electronic representations of an original work based on the notion of a paper book.

With this book, I'm exploring a different approach. I think of the canonical form of this book as the web site. The paper book is a selection of material from the web site, arranged in a manner that makes sense for print.

It doesn't attempt to include all the refactorings in the canonical book, particularly since I may well add more refactorings to the canonical web book in the future. Our intention is that when you buy a copy of Refactoring, 2nd Ed, you might buy it at a bookstore in its physical form, or online in any form. The most essential thing you get for your money is permanent access to the web site. You can read the physical book, and access the web site whenever you need. This raises a question of what role ebooks such as epubs and kindle books should play.

There is a strong argument that they should contain all the information on the web site, after all physical size isn't a factor, and ebooks can be updated easily if I add new material.

However the book industry doesn't think that way, they expect ebooks to have the same content as the physical books, so the ebook versions of refactoring will follow that principle, at least for now.

There is somewhat of a shift away from a purely class-based structure but my aim has been not to change the scope of the book too much. So I followed a rule of not letting the second edition venture into new topic areas. My general plan was take each refactoring in the first edition, and ask what needs to be done to it for it to be relevant in this slightly altered context.

In a few happy cases I could take the refactoring pretty much as it was, do a simple rewrite of the example into JavaScript, and be done with it. Usually however it required a significant rethink of the mechanics and the example. Sometimes it meant the original refactoring was replaced by something similar.

But I did explore some essays on using refactoring to help explore various architectural problems in and early I enjoyed writing them, and they indicated a vehicle I could easily use more in the future. Early in February my editor at Pearson sent out the current state of the book to various people for a technical review. This is a vital part of the process for writing a book, any author will make mistakes, and I make plenty.

Reviewers help catch those, and also highlight things that are not clearly explained. When I started the book I gathered together a panel of people to do on-going review. Their feedback has helped enormously. But at some point I need someone to step back and take a fresh look at the whole book, which is where these recent reviewers have come in.

Michael who has reviewed previous books for me feeds me lots of good suggestions for additional material that would take years to follow up on, so I have to let most of those go by. Michael is particularly good at this, he must have installed several compilers into his wetware, which is one reason why I find him such a good reviewer.

William Chargin is challenging him however, so I feel doubly blessed. Clarifications are often the hardest to figure out. People will always have difficulties with bits of a book, trying to fix every individual difficulty would be cure worse than the disease - the book would have to be much bigger, and the prose would get so stilted that it would be tedious to read.

An example of this was the way I laid out nested functions in the opening example confused three of the panel, so I knew I had to try a different approach.

I always rather enjoy working through review comments. This stage is particularly good as it forces me to step back too.

Now I can look at the material as a whole, yet still dive down to sort out important details. That sounds rather convoluted, but there is a process here. Every candidate book submitted to the series is sent to all the authors in the series, and I ask for their opinion. In that case, they helped me decide to reject myself. This time they felt it was an easy inclusion, which reinforced my feeling that it was a good fit.

And there is some vacation in there, which I hope will help rejuvenate me a bit. I had hoped to have finished the text before I went away, but there were still some review comments that needed work. I also got a final batch of comments just before I left. So this week I made my first pass through that final batch and now just have the outstanding todos from the reviews.

The good news is that I only have fourteen of them. I will hopefully get through them over the next two weeks before I have to hit the road again. Another topic on the book this week was starting to think about the cover. The core cover design is already settled, as it will be part of my signature series, but it does mean I have to pick a photo of a bridge.The next section, the bulk of the book, is a detailed reference to the patterns themselves.

Next I have to go through the final proofs of the pages, and dealing with some composition questions that Alina has. I suspect my feelings here are shared by other authors, which may explain why so many struggle with revised editions, or later installments of a multi-volume work. But a further force has been tugging at me. I try to create examples that are just complicated enough to show the main point, but no more complicated that that.

Musings on Ebooks

People are familiar with the first edition, have got used to its flaws, and like elements in the original that I decided to change. The split-infinitive rule only exists to ape latin, for example. Although many of his changes make me shrug, many of them are distinct improvements to my wording including one in this sentence.

There is somewhat of a shift away from a purely class-based structure but my aim has been not to change the scope of the book too much.
