Kurzbeschreibung
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.

Format:Taschenbuch
C++ Template Metaprogramming bietet einen recht guten Einstieg für das Benutzen der MPL, der Metaprogramming Library, die Bestandteil der Boost-Bibliotheken ist: es füllt einige der Lücken auf, die in der Originaldokumentation fehlen. Leider nur einige. Ich hätte mir gewünscht, mehr direkt über die Innereien der Bibliothek zu erfahren. So bleibt einem nichts weiter übrig, als in die Quellcodes zu steigen, was dann dazu führt, dass man sich die Präprozessor-Bibliothek der Boost-Suite gleich mit reinziehen kann. Das letzte Drittel des Buches dreht sich dann um den dominierenden Anwendungsfall der Metaprogrammierung: das Schreiben neuer Sprachen innerhalb von C++.
Fazit: ob Sie viel von dem Buch haben, hängt stark von Ihrem Vorwissen ab. Ich würde empfehlen, als Einstieg zunächst "Generative Programming" (Czarnecki,Eisenecker) zur Hand zu nehmen. Grundlegende Kenntnisse der funktionalen Programmierung und des Lamda-Kalküls sind ebenfalls angeraten. Und natürlich sollten Sie mehr als nur Durchschnittskenntnisse in C++ mitbringen.
Wenn als das auf Sie zutrifft, werden Sie mit mir vielleicht als Hauptmangel des Buchs festhalten: es ist zu kurz, deshalb nur vier Punkte.

An interesting book...
30. Dezember 2004
Format:Taschenbuch
This is a really interesting book. The template metaprogramming technical topics covered are extremely advanced, and right at the leading edge of C++ library development, yet the step-by-step presentation makes the material understandable even to intermediate programmers. Since the book draws its examples from code that works with the Boost libraries (supplied on a CD), readers can try the examples and play around with them to see how they work.
Some of the libraries discussed (Boost Type Traits, Boost Bind) are well along to becoming part of the C++ standard via a library technical report, so they will eventually become available to every C++ programmer. The bulk of the book is devoted to the Boost Metaprogramming Library, which packages up a lot of advanced techniques into accessible form.
One issue with template metaprogramming is that compile times can get out of hand. The book includes an appendix with hints on avoiding the problem, together with test timings for a half-dozen popular compilers. I really like the timings; too many other authors make assertions about efficiency without supporting data.
I would guess that this book will be of interest to intermediate and advanced C++ programmers interested in library development. And less interesting to beginning programmers, or programmers who never package up their creations into libraries.

I found the title misleading
25. April 2006
Format:Taschenbuch
This book is called "C++ Template Metaprogramming" but it should be called "Boost MPL API Reference." The first portion of this book covers the basics of template metaprogramming fairly well, but what I wanted the rest of the book to cover were both advanced techniques and real-world applications. What I got was material on how to use the Boost metaprogramming library. This book mostly covers just that library, and the various templates that it offers, but what I felt the book should have provided was not only how the more interesting parts of the MPL were implemented, but also interesting applications of the MPL where some interesting algorithm was made possible by template metaprogramming. I can look up the MPL reference docs online, thank you very much.
To summarize - this is a pretty good introduction to template metaprogramming, but seems to be suited for the unlikely position of someone who wants or needs to use this technique, but isn't academically interested in it, and so mainly needs a walkthrough of the set of standard functions available as part of the MPL.
This book is a bad choice for those interested in template metapgramming and wondering if it might help them, but want to learn more about it and its applications first.

Necessary book for template library writers.
20. Januar 2005
Format:Taschenbuch|Von Amazon bestätigter Kauf
This book describes the boost MPL library. Its a very useful guide to this library and it includes enough examples to walk you through how to use it.
Secondly the book explains Meta-programming. This is a new concept to a lot of C++ programmers and old hat to LISP programmers. The C++ pre-compiler is constrained to integral types as constraints. But there are a host of tricks you can use within that constraint to build libraries that adapt to their calling structure. Thus generating code that is as efficient as hand written. Of course with your compiler, your milage may vary.
The other great thing about using this library, MPL, is that where you would write repeticious template code for every parameter in a template'd library like Tuples, you can automate with it with MPL.
Meta programming is a pretty new concept within the C++ community and this book will give us a common language to talk about it. There are other resources on the net, but this book pulls them together.
Highly recommended for expert C++ programmers, C++ Library writers and intermediate programmers study'ing to become experts. If you finished Andrei's book, "Modern C++ Design", this is a great next book to buy and own.
