在C ++中打印彩色文本到控制台 [英] Print Coloured Text to Console in C++

问题描述

我可以做一些类似的操作（基本上是printf的包装器）：

/ p>

  Console :: Print（This is an non-colored message\ n）; 
 Console :: Warning（This is a YELLOW warning message\\\
）; 
 Console :: Error（这是一个RED错误消息\\\
）; 
  

如何在Windows控制台上打印不同颜色的文本？

解决方案

查看本指南。我会做一个自定义的操纵器，所以我可以做一些像：

  std :: cout< 标准文本<< setcolour（红色）<< 红色文本<< std :: endl; 
  

这里是关于如何实现自己的操纵器的小指南。

示例：

  #include< iostream> 
 #include< windows.h> 
 #include< iomanip> 
 
 using namespace std; 
 
枚举color {DARKBLUE = 1，DARKGREEN，DARKTEAL，DARKRED，DARKPINK，DARKYELLOW，GREY，DARKGRAY，BLUE，GREEN，TEAL，RED，PINK，YELLOW，WHITE} 
 
 struct setcolour 
 {
 color _c; 
 HANDLE _console_handle 
 
 
 setcolour（color c，HANDLE console_handle）
：_c（c），_console_handle（0）
 {
 _console_handle = console_handle; 
} 
}; 
 
 //我们可以在这里使用一个模板，使其更通用。宽流不会
 //使用此版本。 
 basic_ostream< char> & operator<<（basic_ostream< char>& s，const setcolour& ref）
 {
 SetConsoleTextAttribute（ref._console_handle，ref._c）; 
 return s; 
} 
 
 int main（int argc，char * argv []）
 {
 HANDLE chandle = GetStdHandle（STD_OUTPUT_HANDLE）; 
 cout<< 标准文本<< setcolour（RED，chandle）<< 红色文本<< endl; 
 
 cin.get（）; 
} 
  

I would like to write a Console class that can output coloured text to the console.

So I can do something like (basically a wrapper for printf):

Console::Print( "This is a non-coloured message\n" );
Console::Warning( "This is a YELLOW warning message\n" );
Console::Error( "This is a RED error message\n" );

How would I print different coloured text to the Windows Console?

解决方案

Check out this guide. I would make a custom manipulator so I could do something like:

std::cout << "standard text" << setcolour(red) << "red text" << std::endl;

Here's a small guide on how to implement your own manipulator.

A quick code example:

#include <iostream>
#include <windows.h>
#include <iomanip>

using namespace std;

enum colour { DARKBLUE = 1, DARKGREEN, DARKTEAL, DARKRED, DARKPINK, DARKYELLOW, GRAY, DARKGRAY, BLUE, GREEN, TEAL, RED, PINK, YELLOW, WHITE };

struct setcolour
{
   colour _c;
   HANDLE _console_handle;


       setcolour(colour c, HANDLE console_handle)
           : _c(c), _console_handle(0)
       { 
           _console_handle = console_handle;
       }
};

// We could use a template here, making it more generic. Wide streams won't
// work with this version.
basic_ostream<char> &operator<<(basic_ostream<char> &s, const setcolour &ref)
{
    SetConsoleTextAttribute(ref._console_handle, ref._c);
    return s;
}

int main(int argc, char *argv[])
{
    HANDLE chandle = GetStdHandle(STD_OUTPUT_HANDLE);
    cout << "standard text" << setcolour(RED, chandle) << " red text" << endl;

    cin.get();
}
