Learning D

By: Michael Parker

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.

Navigating Phobos

Although there are range-based functions in many modules in Phobos, the focus of this section is on those found in std.range, std.algorithm, and std.array. The functions in these modules are often central to composable pipelines. We aren't going to cover all of them, just enough to give you a taste of what is possible and where to find the functions you might need. An in-depth treatment of these modules would span more pages than we have room for.


Note that while many of the functions in these modules are usable in function pipelines, some of them are not, either because they have a return type of void, or they do not take a range as the first parameter. Although this chapter is focused on composable pipelines, we will still take a look at a few of these misfit functions as they can be quite useful to initialize a range before pipelining or to do something with the result of a pipeline.


The std.range package exposes two modules, std.range.interfaces and std.range...
