ANSI format stream manipulators

Header only file for ANSI format stream manipulators.

Usage

There are some default provided manipulators: format::bold(bool), format::italic(bool) and format::underline(bool) will apply their corresponding format to the stream.

Additional SGR formats can be specified by using format::binary<int, int>(bool) where the first int is the ANSI SGR code to turn the feature on, the second the one to turn it off.

format::fg(uint8_t) and format::bg(uint8_t) will apply text and background xterm 8-bit color respectively. format::fg(uint8_t r, uint8_t g, uint8_t b) and its format::bg equivalent will apply true color. format::fg_default and format::bg_default is used for terminal default color.

Example

#include "inc/ansi_format.hpp"
#include <iostream>

using blink = format::binary<5, 25>;

int main() {
	
    std::cout << format::bold(true) << "this is bold. ";
    std::cout << blink(true) << "This is also bold and might be blinking if your terminal supports it. ";
    std::cout << format::bold(false) << blink(false) << format::italic(true) << "This is italic. ";
    std::cout << format::clear << "Everything is back to normal." << std::endl;
    
    std::cout << format::fg(42) << "Colored text, ";
    std::cout << format::bg(0x23, 0x11, 0x7A) << "with colored background. ";
    std::cout << format::fg_default <<  "Back to default text color. ";
    std::cout << format::clear << "Normal text again." << std::endl;
    
}
