color

部分借鉴自：colored-cout

usage

项目是header-only（仅头文件）的，直接include就能用（至少需要C++11）。如果需编译范例，编译时确认文件格式是UTF-8带BOM的。
我们来看看，头文件的使用是多么方便吧，只需要把cout改为rd_cout：

std	basic color	256 color	true color
std::cout	color_ostream::rd_cout	color_ostream::rd256_cout	color_ostream::rdtrue_cout
std::wcout	color_ostream::rd_wcout	color_ostream::rd256_wcout	color_ostream::rdtrue_wcout
std::cerr	color_ostream::rd_cerr	color_ostream::rd256_cerr	color_ostream::rdtrue_cerr
std::wcerr	color_ostream::rd_wcerr	color_ostream::rd256_wcerr	color_ostream::rdtrue_wcerr
std::clog	color_ostream::rd_clog	color_ostream::rd256_clog	color_ostream::rdtrue_clog
std::wclog	color_ostream::rd_wclog	color_ostream::rd256_wclog	color_ostream::rdtrue_wclog

note

256 color和true color的支持需要相应的terminal支持，如Windows terminal， Visual studio调试控制台，MacOS下的terminal.app，iterm2均支持256 color

example file

hello.cpp:

//hello.cpp
#include "color_ostream.h"

using namespace color_ostream;

int main() {
    rd_wcout.imbue(std::locale(std::locale(),"",LC_CTYPE));
    rd_wcout << L"你好，沃德\n";
    rd_wcout << L"你好，世界\n";
    rd_wcout << L"哈啰，世界\n";

    rd256_wcout << L"\n256 color" << std::endl;
    rd256_wcout << L"你好，沃德\n";
    rd256_wcout << L"你好，世界\n";
    rd256_wcout << L"哈啰，世界\n";

    rdtrue_wcout << L"\ntrue color" << std::endl;
    rdtrue_wcout << L"你好，沃德\n";
    rdtrue_wcout << L"你好，世界\n";
    rdtrue_wcout << L"哈啰，世界\n";
    return 0;
}
