在 C++ 中将彩色文本打印到控制台

Question

我想写一个控制台类，可以将彩色文本输出到控制台。

所以我可以做类似的事情（基本上是 printf 的包装器）：

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" );

如何将不同颜色的文本打印到 Windows 控制台？

Answer 1

查看this guide。我会制作一个自定义操纵器，这样我就可以执行以下操作：

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

Here 是关于如何实现自己的操纵器的小指南。

快速代码示例：

#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();
}

我搜索了“c++ 控制台编写彩色文本”，并在大约 4 或 5 点时找到了 this page。由于该网站有一个复制和粘贴部分，我想我会在这里发布（链接上的另一个问题rot 也提示了这个）：

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

using namespace std;

enum Color { DBLUE=1,GREEN,GREY,DRED,DPURP,BROWN,LGREY,DGREY,BLUE,LIMEG,TEAL,
    RED,PURPLE,YELLOW,WHITE,B_B };
/* These are the first 16 colors anyways. You test the other hundreds yourself.
   After 15 they are all combos of different color text/backgrounds. */

bool quit;

void col(unsigned short color)
{
    HANDLE hcon = GetStdHandle(STD_OUTPUT_HANDLE);
    SetConsoleTextAttribute(hcon,color);
}

istream &operator>> ( istream &in, Color &c )
{
    int tint;
    cin >> tint;
    if (tint==-1) quit=true;
    c=(Color)tint;
}

int main()
{
    do {
        col(7); // Defaults color for each round.
        cout << "Enter a color code, or -1 to quit... ";
        Color y;
        cin >> y; // Notice that >> is defined above for Color types.
        col(y); // Sets output color to y.
        if (!quit) cout << "Color: " << (int)y << endl;
    } while (!quit);
    return 0;
}

#include <windows.h>

using namespace std;

int main()

    hOut = GetStdHandle(STD_OUTPUT_HANDLE);

使用这些功能

enum c_color{BLACK=30,RED=31,GREEN=32,YELLOW=33,BLUE=34,MAGENTA=35,CYAN=36,WHITE=37};
enum c_decoration{NORMAL=0,BOLD=1,FAINT=2,ITALIC=3,UNDERLINE=4,RIVERCED=26,FRAMED=51};
void pr(const string str,c_color color,c_decoration decoration=c_decoration::NORMAL){
  cout<<"\033["<<decoration<<";"<<color<<"m"<<str<<"\033[0m";
}

void prl(const string str,c_color color,c_decoration decoration=c_decoration::NORMAL){
   cout<<"\033["<<decoration<<";"<<color<<"m"<<str<<"\033[0m"<<endl;
}
