Introduction
This article illustrates a snippet that permits to add color to console messages.
Background
Well, does it really need any comments?
Using the code
This sample shows how to use the library:
#include "ConsoleColor.h"
std::cout << green << "This text is written in green"
<< white << std::endl;
std::cout << color(FOREGROUND_RED|FOREGROUND_GREEN)
<< "This text has a really exiting color !"
<< white << std::endl;
Now here is the "library":
#pragma once
#include <iostream>
#include <windows.h>
inline std::ostream& blue(std::ostream &s)
{
HANDLE hStdout = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hStdout, FOREGROUND_BLUE
|FOREGROUND_GREEN|FOREGROUND_INTENSITY);
return s;
}
inline std::ostream& red(std::ostream &s)
{
HANDLE hStdout = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hStdout,
FOREGROUND_RED|FOREGROUND_INTENSITY);
return s;
}
inline std::ostream& green(std::ostream &s)
{
HANDLE hStdout = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hStdout,
FOREGROUND_GREEN|FOREGROUND_INTENSITY);
return s;
}
inline std::ostream& yellow(std::ostream &s)
{
HANDLE hStdout = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hStdout,
FOREGROUND_GREEN|FOREGROUND_RED|FOREGROUND_INTENSITY);
return s;
}
inline std::ostream& white(std::ostream &s)
{
HANDLE hStdout = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hStdout,
FOREGROUND_RED|FOREGROUND_GREEN|FOREGROUND_BLUE);
return s;
}
struct color {
color(WORD attribute):m_color(attribute){};
WORD m_color;
};
template <class _Elem, class _Traits>
std::basic_ostream<_Elem,_Traits>&
operator<<(std::basic_ostream<_Elem,_Traits>& i, color& c)
{
HANDLE hStdout=GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hStdout,c.m_color);
return i;
}
