color

中文说明
Partly learned from: colored-cout

usage

Project is header-only,you can use it via directly include it(at least C++11）
Let's see, how convenient is our header:
all you need to do is changing cout to 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

support for 256 color and true color needs corresponding support in terminal,such as Windows terminal, Visual studio debug console, MacOS terminal.app, iterm2 all support 256 color.

sample

example file

hello.cpp:

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

using namespace color_ostream;

int main([[maybe_unused]] int argc, [[maybe_unused]] char *argv[]) {
    rd_wcout.imbue(std::locale(std::locale(),"",LC_CTYPE));
    rd_wcout << L"Hello world\n";
    rd_wcout << L"Hola Mundo\n";
    rd_wcout << L"Bonjour le monde\n";

    rd256_wcout << L"\n256 color" << std::endl;
    rd256_wcout << L"Hello world\n";
    rd256_wcout << L"Hola Mundo\n";
    rd256_wcout << L"Bonjour le monde\n";

    rdtrue_wcout << L"\ntrue color" << std::endl;
    rdtrue_wcout << L"Hello world\n";
    rdtrue_wcout << L"Hola Mundo\n";
    rdtrue_wcout << L"Bonjour le monde\n";
    return 0;
}

color.cpp:

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

using namespace color_ostream;
using namespace std;

int main([[maybe_unused]] int argc, [[maybe_unused]] char *argv[]) {
    std::cout << clr::red     << " red "
              << clr::yellow  << " yellow "

    std::cout << clr::red     << clr::on_cyan    << " red "
              << clr::yellow  << clr::on_blue    << " yellow "
