Abstract

Template metaprograms have become an essential part of today's C++ programs: with proper template definitions we can force the C++ compiler to execute algorithms at compilation time. Among the application areas of template metaprograms are the expression templates, static interface checking, code optimization with adaptation, language embedding and active libraries. Despite all of its already proven benefits and numerous successful applications there are surprisingly few tools for creating, supporting, and analyzing C++ template metaprograms. As metaprograms are executed at compilation time they are even harder to understand. In this paper we present a code visualization tool, which is utilizing Tem plight, our previously developed C++ template metaprogram debugger. Using the tool it is possible to visualize the instantiation chain of C++ templates and follow the execution of metaprograms. Various presentation layers, filtering of template instances and step-by-step replay of the instantiations are supported. Our tool can help to test, optimize, maintain C++ template metaprograms, and can enhance their acceptance in the software industry.

c++模板元程序的可视化

模板元程序已经成为当今c++程序的重要组成部分:通过适当的模板定义，我们可以强制c++编译器在编译时执行算法。模板元程序的应用领域包括表达式模板、静态接口检查、自适应代码优化、语言嵌入和活动库。尽管已经证明了c++模板元程序的所有优点和许多成功的应用程序，但令人惊讶的是，用于创建、支持和分析c++模板元程序的工具很少。由于元程序是在编译时执行的，因此更难以理解。本文利用自己开发的c++模板元程序调试器Tem的特点，开发了一种代码可视化工具。使用该工具可以可视化c++模板的实例化链，并跟踪元程序的执行。支持各种表示层、模板实例过滤和实例化的逐步重播。我们的工具可以帮助测试、优化、维护c++模板元程序，并且可以提高它们在软件行业中的接受度。
