Learning D

Leverage the modern convenience and modelling power of the D programming language to develop software with native efficiency

About This Book

• Acquire the skills to understand the fundamentals of D through its support for imperative and object-oriented programming
• Take advantage of D's powerful compile-time features, templates and ranges to apply generative, generic, and functional style
• A systematic guide that will help you become familiar with the concepts in D with the help of simple and easy-to-understand examples

Who This Book Is For

This book is intended for those with some background in a C-family language who want to learn how to apply their knowledge and experience to D. Perhaps you're a college student looking to use D for hobby projects, or a career programmer interested in expanding your skillset. This book will help you get up to speed with the language and avoid common pitfalls that arise when translating C-family experience to D.

What You Will Learn

• Compile programs with DMD and manage projects with DUB
• Work efficiently by binding your D programs with new and existing C libraries
• Generate code at compile-time to enhance runtime performance
• Implement complex templates for more powerful generic code
• Write idiomatic D with range-based functional pipelines
• Use the DUB repository to find a link with a variety of D libraries
• Implement a web-app in D from the ground up

In Detail

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.
