Even bad code can function. But if code isn’t clean, it can bring a development organization to its knees. Every year, countless hours and significant resources are lost because of poorly written code. But it doesn’t have to be that way.
Noted software expert Robert C. Martin, presents a revolutionary paradigm with Clean Code: A Handbook of Agile Software Craftsmanship. Martin, who has helped bring agile principles from a practitioner’s point of view to tens of thousands of programmers, has teamed up with his colleagues from Object Mentor to distill their best agile practice of cleaning code “on the fly” into a book that will instill within you the values of software craftsman, and make you a better programmer―but only if you work at it.
What kind of work will you be doing? You’ll be reading code―lots of code. And you will be challenged to think about what’s right about that code, and what’s wrong with it. More importantly you will be challenged to reassess your professional values and your commitment to your craft.
Clean Codeis divided into three parts. The first describes the principles, patterns, and practices of writing clean code. The second part consists of several case studies of increasing complexity. Each case study is an exercise in cleaning up code―of transforming a code base that has some problems into one that is sound and efficient. The third part is the payoff: a single chapter containing a list of heuristics and “smells” gathered while creating the case studies. The result is a knowledge base that describes the way we think when we write, read, and clean code.
Readers will come away from this book understanding
How to tell the difference between good and bad code How to write good code and how to transform bad code into good code How to create good names, good functions, good objects, and good classes How to format code for maximum readability How to implement complete error handling without obscuring code logic How to unit test and practice test-driven development What “smells” and heuristics can help you identify bad codeThis book is a must for any developer, software engineer, project manager, team lead, or systems analyst with an interest in producing better code.

Excellent for the whole team
As CTO of a software company I co-founded, I’m not only looking for books that help me improve individually, but also books that the whole development team – from developers to architects – may find useful. Robert C. Martin’s Clean Code does both, and, like the good code described therein, it’s well written, clear, and easy to read. Martin includes many helpful examples and his suggestions are applicable to any programming language.Ideally, each developer takes charge of their own education and is constantly improving their skillset, an aspect that Martin covers in The Clean Coder. I view it as an important part of my job to help my team improve. To do so, I distill a lot of written material down to actionable components and provide that to my development team. Concepts from Clean Code have become very helpful guides for them. Below are a few of my favorite takeaways.The first is what Martin calls The Boy Scout Rule: “Leave the campground a little cleaner than you found it.” It’s a great concept, not only because it’s simple to follow, but also because it has broad applicability and can be used on any project. Essentially, when a team member works on a piece of code, they should aim to improve it somehow by the time their task is finished. A few examples of this among many are: fixing an unclear variable name, breaking up a large function into smaller functions, or cleaning up a conditional for improved clarity. With everyone on the team doing this, the code improves over time and everyone feels responsible for the code whether they wrote it personally or not. Even if something can’t be addressed immediately, developers are encouraged to log the issues they see.Another of my favorite takeaways is the Three Laws of TDD, a concept I was able to quickly roll out to the team as a framework to follow for how TDD should be conducted on a project. This virtually ensures that all of your product code has test coverage. It also helps make most of your code SOLID (https://en.wikipedia.org/wiki/SOLID_%28object-oriented_design%29), since code that is built in this fashion is structured with SOLID concepts in mind. This is a must for effective testing.Finally, the topics of proper identifier names and commenting really resonated with me and my team. In our company, we tend to “adopt” existing codebases – projects that have already been started by other developers whose code is of widely varying quality. If we’re lucky, it’s structured well and demonstrates best practices and approaches in how it’s constructed. Unfortunately, the code is sloppy at times and requires some TLC to get it in shape. A part of that process is understanding what the existing application does. As Clean Code correctly outlines, many comments are superfluous or even plain wrong and misleading. As a team, we don’t blindly trust the accuracy of existing comments and instead go right to the application’s code to determine what it does. This is where proper naming comes into play. With good names, the code reads like comments or as a narrative of what the application does, nullifying most needs for additional commenting. Simply put, the code comments itself. We also use refactoring tools to improve names and clean up comments as we go. Of course, by doing so, we’re also applying the Boy Scout Rule.Overall, Clean Code is a wonderful book with much useful and immediately-applicable information for developers of all levels. If you’re looking for a book that will help make you a better developer, this will.

Top 10 Books on SW Development – A Must Read
I first met Bob Martin 15 years ago by reading his brilliantly lucid _Designing Object Oriented C++ Applications Using The Booch Method_. He was kind enough to help me sort out my own struggles with the writings of the “Three Amigos” and I’ve been something of a fan ever since.He followed with a number of excellent books; took the lead first on Patterns and then on Agile development; but now he has reached beyond his dedicated audience of serious software architecture geeks, with this extraordinary work on writing code well.This book ranks on any shelf that has either Code Complete by Steve McConne or Refactoring by Martin Fowler; both classics (though loyalty and enjoyment causes me to add Why Software Sucks by David Platt as belonging on that shelf as well).It is true that seasoned developers will find that they “already know” much of what is in the early portion of the book — but my experience is that Martin has a unique ability to crystalize even common wisdom in a way that gives accepted practice new impetus and that expands my understanding of the implications of tenets I hold to but don’t always fully implement.Bob Martin is known to many of us as “Uncle Bob,” and with good reason; his writing is avuncular in the finest sense of being solid advice offered in good cheer and without condescension.All of that said, this is not a light weight book; while offering up the fundamental principles that separate yeoman programmers from the truly expert, he goes on to teach more (and more effectively) about test driven development in one chapter than most authors accomplish in a book. He does the same for refactoring and, I would argue, on the way he offers a brilliant introduction to Agile programming.While we’re at it, let’s note that the chapters on naming and on comments would serve well as a standard for any software development group and should certainly be required reading for all new developers.In short, this book is recommended without reservation to those who are not yet convinced they know all that can be known about creating great software. I own both the electronic and the hardcover version, and it was money very well spent.

Ein Muss für jeden, der besser programmieren will – nicht nur für Anfänger„Clean Code“ hat mir persönlich sehr gut gefallen und ich würde es jedem empfehlen, der sich ernsthaft mit Softwareentwicklung beschäftigt – egal ob Anfänger oder erfahrener Entwickler.Als Ergänzung beim Programmieren lernen:Gerade wenn man neu ins Programmieren einsteigt, ist das Buch eine perfekte Ergänzung, weil es nicht nur zeigt, was man programmieren soll, sondern wie man es sauber und verständlich macht. Es geht weit über Syntax und Sprache hinaus und behandelt die Prinzipien guten Codes – etwas, das in vielen Kursen oft zu kurz kommt.Auch für Fortgeschrittene absolut lesenswert:Auch wenn man schon programmieren kann, lohnt sich die Lektüre. Das Buch hilft, schlechte Angewohnheiten zu erkennen und zu reflektieren, die sich im Laufe der Zeit eingeschlichen haben. Es geht dabei nicht um theoretische Regeln, sondern um praktische, nachvollziehbare Beispiele und konkrete Tipps, die man direkt umsetzen kann.Fazit:„Clean Code“ sollte jeder Programmierer kennen und gelesen haben. Es hat mir geholfen, meinen Code strukturierter, lesbarer und verständlicher zu schreiben – was nicht nur mir, sondern auch meinen Kollegen zugutekommt. Absolute Empfehlung für alle, die sauberen, wartbaren Code schreiben wollen – ein echter Klassiker der Softwareentwicklung.

This book has changed the way I code, hopefully for the better! Fittingly for a book about clean coding, it is cleanly written with clear examples and case studies.

Excelente libro

Es un libro de lectura trivial; lo difícil es aplicar lo que nos parece buena idea en todo momento y ser consistentes con el esfuerzo.Yo creo que más que leérselo hay que resumirlo, tomar lo que a uno le interesa e interiorizarlo; y eso no es tan fácil como pueda parecer. Habré leído este libro al menos 3 veces, lo tengo resumido y con todo, de vez en cuando voy al resumen a la zona de malos olores y me doy cuenta de que hay cosas que en las que se puede mejorar.La parte de la refactorización en la que incide mucho el autor, es muy muy pesada; aunque compensa con creces el esfuerzo.
