It works by overriding std::streambuf to intercept what you print to std::cout and decorate it with ANSI escape codes for colored text

Features

• **Rainbow **: Automatically cycles through colors for each space-separated word
• Specific Colors: Set output to any supported color by name

Installation

Simply include the header file in your C++ project:

#include "ColoredBuffer.hpp"  
// Create ColoredBuffer instance and wrapper
ColoredBuffer rb(std::cout.rdbuf());
wrapper guard(rb);  
// Now all std::cout output will be colored!

Available Methods

// Enable rainbow cycling (changes color on each space)
rb.rainbow();

// Set a specific color by name
rb.set_color("blue");
rb.set_color("green");

// Disable coloring (resets to default)
rb.disable();

// Show available colors
rb.check_avaiable_colors();

Example Program

#include <iostream>
#include "ColoredBuffer.hpp"

int main() {
    ColoredBuffer rb(std::cout.rdbuf());
    wrapper guard(rb);  

    rb.rainbow();
    std::cout << "This text cycles through rainbow colors word by word!\n";
    rb.disable();

    rb.set_color("yellow");
    std::cout << "Now printing in yellow.\n";

    rb.set_color("cyan");
    std::cout << "And now in cyan.\n";

    rb.set_color("darkgreen"); // not supported -> shows available colors
}

Output

Supported Colors

• red
• green
• yellow
• blue
• magenta
• cyan

You can easily add more colors by extending the colors vector with new Color entries by just adding a name aswell its corresponding ANSI Color Code

how to improve

instead of using a vector to store the Colors, consider using a Enum. trying to access colors that are not present will now be a compile time error.

what i learned

• basic understanding on how iostream/streams really work
• why RAII wrappers are important
• using error codes can be more useful than writing methods - like i did in check_avaiable_colors
