C++相比于C来说复杂得多,被头文件所坑害的程序员也不在少数。为了解决头文件机制的痛点(编译慢,顺序相关等),各种奇奇怪怪的idiom层出不穷,给可怜的程序员们带来了极大的心智负担上。C++苦头文件久矣,然而由于历史的惯性,到C++20之前,仍然没有抛弃这套机制。现在,C++20来了,正式宣告对头文件机制的修修补补真正...

这个版本我们对 C++20 Modules 的实现进行了重构和改进,改进了模块文件的依赖图解析,新增了对 STL 和 User HeaderUnits 的支持,同时让 CMakelists/compile_commands 生成器也支持了 C++ Modules。 Xmake 是一个基于 Lua 的轻量级跨平台构建工具。
其中std::print的格式化语法同格式化库,可以参考Using C++20 Formatting Library。而std::println则会在输出的内容之后添加一个换行,这是对比了C/Java/Rust/Go/C#/.Net等等语言之后作出的选择。 关于性能,可能看看作者的对比结果: 可以看到,printf与print几乎要比cout快三倍,print默认会打印到stdout。当打印到cout并...
Note:Enabling C++20 requires CMake 3.12 or higher. Visual Studio ships with the latest version of CMake, but this may be a consideration if you use this project across operating systems or need to use an older version of CMake. You will also need to make sure you are using the Visual...
So, as of today, where do we stand with meson support for C++20 modules? I am willing to ditch CMake for Meson at this point if that support is there. And it is unclear where or how the Ninja support factors in with Meson. CMake supports Fortran, but no indication as far as I ...
(or build systems) to provide a text argument to it which represents some header name as the compiler would see. A quick example is:$ cl /std:c++latest /EHsc /experimental:module /module:exportHeader "<vector>" /module:showResolvedHeader <vector> Note: resolved <vector> to 'C:\<path...
