Programmers are craftspeople trained to use a certain set of tools (editors, object managers, version trackers) to generate a certain kind of product (programs) that will operate in some environment (operating systems on hardware assemblies). Like any other craft, computer programming has spawned a body of wisdom, most of which isn't taught at universities or in certification classes. Most programmers arrive at the so-called tricks of the trade over time, through independent experimentation. In The Pragmatic Programmer, Andrew Hunt and David Thomas codify many of the truths they've discovered during their respective careers as designers of software and writers of code.
Some of the authors' nuggets of pragmatism are concrete, and the path to their implementation is clear. They advise readers to learn one text editor, for example, and use it for everything. They also recommend the use of version-tracking software for even the smallest projects, and promote the merits of learning regular expression syntax and a text-manipulation language. Other (perhaps more valuable) advice is more light-hearted. In the debugging section, it is noted that, "if you see hoof prints think horses, not zebras." That is, suspect everything, but start looking for problems in the most obvious places. There are recommendations for making estimates of time and expense, and for integrating testing into the development process. You'll want a copy of The Pragmatic Programmer for two reasons: it displays your own accumulated wisdom more cleanly than you ever bothered to state it, and it introduces you to methods of work that you may not yet have considered. Working programmers will enjoy this book. --David Wall
Topics covered: A useful approach to software design and construction that allows for efficient, profitable development of high-quality products. Elements of the approach include specification development, customer relations, team management, design practices, development tools, and testing procedures. This approach is presented with the help of anecdotes and technical problems.
From the Publisher
As a reviewer I got an early opportunity to read the book you are holding. It was great, even in draft form. Dave Thomas and Andy Hunt have something to say, and they know how to say it. I saw what they were doing and I knew it would work. I asked to write this foreword so that I could explain why.
Simply put, this book tells you how to program in a way that you can follow. You wouldn't think that that would be a hard thing to do, but it is. Why? For one thing, not all programming books are written by programmers. Many are compiled by language designers, or the journalists who work with them to promote their creations. Those books tell you how to talk in a programming language---which is certainly important, but that is only a small part of what a programmer does.
What does a programmer do besides talk in programming language? Well, that is a deeper issue. Most programmers would have trouble explaining what they do. Programming is a job filled with details, and keeping track of those details requires focus. Hours drift by and the code appears. You look up and there are all of those statements. If you don't think carefully, you might think that programming is just typing statements in a programming language. You would be wrong, of course, but you wouldn't be able to tell by looking around the programming section of the bookstore.
In The Pragmatic Programmer Dave and Andy tell us how to program in a way that we can follow. How did they get so smart? Aren't they just as focused on details as other programmers? The answer is that they paid attention to what they were doing while they were doing it---and then they tried to do it better.
Imagine that you are sitting in a meeting. Maybe you are thinking that the meeting could go on forever and that you would rather be programming. Dave and Andy would be thinking about why they were having the meeting, and wondering if there is something else they could do that would take the place of the meeting, and deciding if that something could be automated so that the work of the meeting just happens in the future. Then they would do it.
That is just the way Dave and Andy think. That meeting wasn't something keeping them from programming. It was programming. And it was programming that could be improved. I know they think this way because it is tip number two: Think About Your Work.
So imagine that these guys are thinking this way for a few years. Pretty soon they would have a collection of solutions. Now imagine them using their solutions in their work for a few more years, and discarding the ones that are too hard or don't always produce results. Well, that approach just about defines pragmatic. Now imagine them taking a year or two more to write their solutions down. You might think, That information would be a gold mine. And you would be right.
The authors tell us how they program. And they tell us in a way that we can follow. But there is more to this second statement than you might think. Let me explain.
The authors have been careful to avoid proposing a theory of software development. This is fortunate, because if they had they would be obliged to warp each chapter to defend their theory. Such warping is the tradition in, say, the physical sciences, where theories eventually become laws or are quietly discarded. Programming on the other hand has few (if any) laws. So programming advice shaped around wanna-be laws may sound good in writing, but it fails to satisfy in practice. This is what goes wrong with so many methodology books.
I've studied this problem for a dozen years and found the most promise in a device called a pattern language. In short, a pattern is a solution, and a pattern language is a system of solutions that reinforce each other. A whole community has formed around the search for these systems.
This book is more than a collection of tips. It is a pattern language in sheep's clothing. I say that because each tip is drawn from experience, told as concrete advice, and related to others to form a system. These are the characteristics that allow us to learn and follow a pattern language. They work the same way here.
You can follow the advice in this book because it is concrete. You won't find vague abstractions. Dave and Andy write directly for you, as if each tip was a vital strategy for energizing your programming career. They make it simple, they tell a story, they use a light touch, and then they follow that up with answers to questions that will come up when you try.
And there is more. After you read ten or fifteen tips you will begin to see an extra dimension to the work. We sometimes call it QWAN, short for the quality without a name. The book has a philosophy that will ooze into your consciousness and mix with your own. It doesn't preach. It just tells what works. But in the telling more comes through. That's the beauty of the book: It embodies its philosophy, and it does so unpretentiously.
So here it is: an easy to read---and use---book about the whole practice of programming. I've gone on and on about why it works. You probably only care that it does work. It does. You will see. --Ward Cunningham

The Pragmatic Programmer is a collection of ideas, observations, and recommendations for software developers. Throughout the book, they highlight these notions in a set of numbered tips, about 70 of them, which are collected on a single tear-out card situated in the back of the book. Just reading the tips, without reading the text of the book, might make these gems seem trite, empty, and obvious. But, they're not!
Many of the tips actually build upon previous ones, like tip 4: "Don't live with broken windows", which urges programmers to fix problems and clean up messes, and tip 20: "Keep knowledge in plain text." With some books like this you can skip around--but this one is better read from beginning to end.
There is plenty of ideas to consider, agree with, and, perhaps, disagree with, too. You can also feel a little passion. "Conventional wisdom says that once a project is in the coding phase, the work is mostly mechanical, transcribing the design into executable statements. We think that this attitude is the single biggest reason that many programs are ugly, inefficient, poorly structured, unmaintainable, and just plain wrong." Hooray for authors who take a stand and then back it up with well reasoned arguments!
Reading this book isn't a substitute for having that conversation with a colleague about the craft. But, The Pragmatic Programmer is worth listening to in the mean time. It is a good, solid, fun read.
- The advice on metaprogramming is probably the strongest part of the book. I really liked the clarity of the examples. The key idea is that you should program the structure and methods in code, and provide the detailed implementation (business rules, algorithms etc.) as data.
- The advice on code generators, little languages and plain text interfaces is solid advice worth reiterating and the sections on these are good. However, I preferred the treatment offered by Jon Bentley in his really excellent Programming Pearls books
- The section on automation is a healthy reminder that programmers should have a "do it once, or automate" philosophy
- The section on contract-driven development is worthy and echoes current practice. Jon Bentley's version is a more theoretical, conceptual approach, less polluted by particular industry practices.
- The sections on test-driven development is fine, but the ideas are much better handled by Kent Beck's books
The not so good:
- The chapters on Pragmatism, Specification, Team Work and Discipline fit nicely with the general themes of the book, but say very little of practical value. If you are interested in operating in a team environment, this isn't the book you are looking for.
- The section on programming methodologies is so wishy-washy it's hard to know what advice if any to take away from it
- References to specific resources are somewhat out of date (the book was written 15 years ago)
The Pragmatic Programmer is worth the price, but if you are thinking of buying this book because you are a relatively new programmer and are looking for advice, I would strongly suggest first reading the much better books:
Jon Bentley's Programming Pearls and More Programming Pearls
Kernighan and Pike's The Practice of Programming
Kent Beck's Extreme Programming Explained
Another book you might be interested in is Susan Lammers, Programmers at Work. Although it is very old (1989), its interesting that most of the programmers interviewed discuss exactly the same themes picked up in The Pragmatic Programmer.
In case you were also thinking about buying a copy of Code Complete, which is also often recommended to new programmers, also hold off - its far too long and a great deal of it feels like a padded-out outline.
The tips are deceptively simple at times, but only a truly naive or inexperienced reader would miss the rich depth that their combination presents. In fact, that is the real beauty of this book -- it does not present some short-lived miracle-cure approach -- instead, it weaves together small bits of wisdom and practical advice into a powerful work-style.
They have some controversial views -- these authors are witty and opinionated -- but agreeing or disagreeing with each individual idea is not the point -- "seeing the forest" is.
There are numerous specific code examples, but the book is a fun and easy read -- strangely, I also think it would be a wonderful book for someone who is NOT a programmer, but who works with them, perhaps a business manager having a major system built. Even skipping all the really technical parts, it would be a wonderful set of benchmarks to assess how good your programmers really are -- much more powerful than "he has 3 years of C++, 2 years of Linux"...
I am hoping this writing team will follow this book with some specific guides as well, but this one is destined to be a classic. These guys really know what they are talking about, and, as a wonderful bonus, they are terrific writers, as well!
The book has gotten great reviews on slashdot, as well as a couple of programming magazines, including Dr Dobbs and Software Development -- they were well deserved. Buy IT!
