Template Metaprogramming with C++: Learn everything about C++ templates and unlock the power of template metaprogramming

by Marius Bancila

Understand how to use modern C++ templates for writing maintainable, robust, and fast software Learn how the metaprogramming technique enables you to create data structures and functions that allow computation to happen at compile time. With this book, you'll realize how templates help you avoid writing duplicate code and are key to creating generic libraries, such as the standard library or Boost, that can be used in a multitude of programs. The introductory chapters of this book will give you insights into the fundamentals of templates and metaprogramming. You'll then move on to practice writing complex templates and exploring advanced concepts such as template recursion, template argument deduction, forwarding references, type traits, and conditional compilation. Along the way, you'll learn how to write variadic templates and how to provide requirements to the template arguments with C++20 constraints and concepts. Finally, you'll apply your knowledge of C++ metaprogramming templates to implement various metaprogramming patterns and techniques. By the end of this book, you'll have learned how to write effective templates and implement metaprogramming in your everyday programming journey. This book is for beginner-to-intermediate C++ developers who want to learn about template metaprogramming as well as advanced C++ developers looking to get up to speed with the new C++20 features related to templates and the the various idioms and patterns. Basic C++ coding experience is necessary to get started with this book.

At long last!

Template Metaprogramming With C++ is an essential read for professional C++ developers, covering template basics in its opening chapters and delving into arcane depths later on. The coverage of ranges at the end is a welcome addition.

This book would be absolutely goated, and would have 5 stars, if not for the presence of multiple typos and code mistakes that are missing from the errata page online. I also found at least one definition—of Mixins—that is inconsistent with the view of the C++ community as far as I can tell. Nevertheless, this book is certainly worth a read.
