template的一个重要使用方法就是template meta programming,它利用编译器对于template的解释是静态的这一特性,让编译器在编译时做计算,可以有效的提高程序的运行速度。有关于 template meta programming的记载,最早见于Erwin Unruh,他在1994年写了一个用template计算质数的程序。我希望通过这篇文章介绍一些TMP的基本技巧和应...

Similarly, preprocessor (probably the oldest way to do meta-programming) expands the macros and generates the code. In a C++ meta program, the language of the host program and domain language are both C++; this means the C++ compiler generates the C++ code at the time of the instantiation ...
We propose a new extension to the purely functional programming language Haskell that supports compile-time meta-programming. The purpose of the system is to support the algorithmic construction of programs at compile-time. The ability to generate code at compile time allows the programmer to ...
An API for neural networks implemented in C++ with template meta-programming. Perhaps the first of its kind. Include === All the necessary components are in header files (yay templates!) So just add what you need from the include folder. What a Neural Network is === Our...

Fatal (Facebook Template Library) is a library for fast prototyping software in modern C++. It provides facilities heavily based on template meta-programming, while keeping most of the complexity under-the-hood, to enhance the expressive power of C++. ...
