Colour output of program run under BASH [closed]

Answer 1

Here's a version of the code above from @nightcracker, using stringstream instead of itoa. (This runs using clang++, C++11, OS X 10.7, iTerm2, bash)

#include 
#include 
#include 

enum Color
{
    NONE = 0,
    BLACK, RED, GREEN,
    YELLOW, BLUE, MAGENTA,
    CYAN, WHITE
};

static std::string set_color(Color foreground = NONE, Color background = NONE)
{
    std::stringstream s;
    s << "\033[";
    if (!foreground && ! background){
        s << "0"; // reset colors if no params
    }
    if (foreground) {
        s << 29 + foreground;
        if (background) s << ";";
    }
    if (background) {
        s << 39 + background;
    }
    s << "m";
    return s.str();
}

int main(int agrc, char* argv[])
{
    std::cout << "These words should be colored [ " <<
        set_color(RED) << "red " <<
        set_color(GREEN) << "green " <<
        set_color(BLUE) << "blue" <<
        set_color() <<  " ]" << 
        std::endl;
    return EXIT_SUCCESS;
}
