At long last, this much-awaited book delivers practical metaprogramming into the hands of the everyday C++ programmer. Simply put, a metaprogram is a program which generates or manipulates program code. The ability to programmatically create software allows programmers to work at a higher level of abstraction appropriate to the problem domain, and allows the resulting code to be reconfigured without loss of efficiency. Ever since generic programming was introduced to C++, programmers have discovered myriad ´´template tricks´´ for manipulating programs *as they are compiled*, effectively eliminating the barrier between program and metaprogram. While the excitement generated by these capabilities among C++ experts has reached the community at large, their practical application remains out-of-reach for most programmers. This book provides the neccessary foundation to make template metaprogramming practical for everyone. Product Description Abrahams and Gurtovoy have written something close to a classic. marvelous fun to read. Read the complete book review by Jack J. Woehr, Dr. Dobbs Journal, June 03, 2005 If you´re like me, you´re excited by what people do with template metaprogramming (TMP) but are frustrated at the lack of clear guidance and powerful tools. Well, this is the book we´ve been waiting for. With help from the excellent Boost Metaprogramming Library, David and Aleksey take TMP from the laboratory to the workplace with readable prose and practical examples, showing that compile-time STL is as able as its runtime counterpart. Serving as a tutorial as well as a handbook for experts, this is the book on C++ template metaprogramming. -Chuck Allison, Editor, The C++ Source C++ Template Metaprogramming sheds light on the most powerful idioms of today´s C++, at long last delivering practical metaprogramming tools and techniques into the hands of the everyday programmer. A metaprogram is a program that generates or manipulates program code. Ever since generic programming was introduced to C++, programmers have discovered myriad template tricks for manipulating programs as they are compiled, effectively eliminating the barrier between program and metaprogram. While excitement among C++ experts about these capabilities has reached the community at large, their practical application remains out of reach for most programmers. This book explains what metaprogramming is and how it is best used. It provides the foundation you´ll need to use the template metaprogramming effectively in your own work. This book is aimed at any programmer who is comfortable with idioms of the Standard Template Library (STL). C++ power-users will gain a new insight into their existing work and a new fluency in the domain of metaprogramming. Intermediate-level programmers who have learned a few advanced template techniques will see where these tricks fit in the big picture and will gain the conceptual foundation to use them with discipline. Programmers who have caught the scent of metaprogramming, but for whom it is still mysterious, will finally gain a clear understanding of how, when, and why it works. All readers will leave with a new tool of unprecedented power at their disposal-the Boost Metaprogramming Library. The companion CD-ROM contains all Boost C++ libraries, including the Boost Metaprogramming Library and its reference documentation, along with all of the book´s sample code and extensive supplementary material. Features + Benefits At long last, this much-awaited book delivers practical metaprogramming into the hands of the everyday C++ programmer. ° Presents the C++ Metaprogramming Library (MPL), a framework of powerful tools providing unprecedented new capability to the C++ power-user. ° Bjarne Stroustrup gave the equivalent of a blank check to the authors--meaning that he would accept anything they wrote into his Series, given their overwhelming expertise in this domain. ° CD-ROM contains the entire Boost Library.

Templates are among the most powerful features of C++, but they remain misunderstood and underutilized, even as the C++ language and development community have advanced. In C++ Templates, Second Edition, three pioneering C++ experts show why, when, and how to use modern templates to build software that´s cleaner, faster, more efficient, and easier to maintain. Now extensively updated for the C++11, C++14, and C++17 standards, this new edition presents state-of-the-art techniques for a wider spectrum of applications. The authors provide authoritative explanations of all new language features that either improve templates or interact with them, including variadic templates, generic lambdas, class template argument deduction, compile-time if, forwarding references, and user-defined literals. They also deeply delve into fundamental language concepts (like value categories) and fully cover all standard type traits. The book starts with an insightful tutorial on basic concepts and relevant language features. The remainder of the book serves as a comprehensive reference, focusing first on language details and then on coding techniques, advanced applications, and sophisticated idioms. Throughout, examples clearly illustrate abstract concepts and demonstrate best practices for exploiting all that C++ templates can do. Understand exactly how templates behave, and avoid common pitfalls Use templates to write more efficient, flexible, and maintainable software Master today´s most effective idioms and techniques Reuse source code without compromising performance or safety Benefit from utilities for generic programming in the C++ Standard Library Preview the upcoming concepts feature The companion website, tmplbook.com, contains sample code and additional updates.
