Learning D

Overview of this book

D is a modern programming language that is both powerful and efficient. It combines multiple paradigms in a way that opens up a whole new world of software design. It is used to develop both desktop and web applications, with future targets including mobile, and is available on multiple platforms. It is familiar to anyone with some experience in one or more of the C-family languages. However, hidden in the similarities are several differences that can be surprising when trying to apply common idioms from other languages. When learning D on your own, this can make it more time-consuming to master. In order to make the most of the language and become an idiomatic D programmer, it’s necessary to learn how to think in D. This book familiarizes you with D from the ground up, with a heavy focus on helping you to avoid surprises so that you can take your D knowledge to the next level more quickly and painlessly. Your journey begins with a taste of the language and the basics of compiling D programs with DMD, the reference D compiler developed by Digital Mars, and DUB, a community-developed build utility and package manager. You then set out on an exploration of major language features. This begins with the fundamentals of D, including built-in types, conditionals, loops and all of the basic building-blocks of a D program, followed by an examination of D’s object-oriented programming support. You’ll learn how these features differ from languages you may already be familiar with. Next up are D’s compile-time features, such as Compile-Time Function Evaluation and conditional compilation, then generic programming with templates. After that, you’ll learn the more advanced features of ranges and functional pipeline programming. To enhance your D experience, you are next taken on a tour of the D ecosystem and learn how to make D interact with C. Finally, you get a look at D web development using the vibe.d project and the book closes with some handy advice on where to go next.

About the Reviewers


There was a time when D libraries were scattered all over the internet, on several different project hosting sites and private servers. Today, though there are still some rogue projects out there that have yet to jump on the bandwagon, the DUB Registry has become the hub of D library activity. In this section, we're first going to talk about the registry itself, specifically about how to use registered projects and how to register new ones.

The DUB registry lives at Its primary purpose is to serve as the main database for DUB-enabled projects. Although the registry is not restricted to libraries, they are where our attention will be directed. A library in the DUB registry is globally available as a dependency to any DUB-enabled project. When you have a need in your project that is not covered by the standard library, this is the first place to look before rolling up your sleeves to develop your own solution.
