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...

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 ...
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++. ...

可以说,它要比C语言要简单的多。如果我们把模板当做是一门语言来学习,那只需要花费学习OO零头的时间即可掌握。按照这样的思路,可以说在各种模板书籍中出现的多数技巧,都可以被轻松理解。 简单回顾一下模板的历史。87年的时候,泛型(Generic Programming)便被纳入了C++的考虑范畴,并直接导致了后来模板语法的产生。可以...
