Is there a way to print colored output using iostream and Xcode? I'd like to be able to, for example, print Hello World! with Hello red, World blue and ! yellow. How can I do that?
Answer
You need the terminal color codes. For linux it's the following (your system might be different, look it up):
//the following are UBUNTU/LINUX, and MacOS ONLY terminal color codes.
#define RESET "\033[0m"
#define BLACK "\033[30m" /* Black */
#define RED "\033[31m" /* Red */
#define GREEN "\033[32m" /* Green */
#define YELLOW "\033[33m" /* Yellow */
#define BLUE "\033[34m" /* Blue */
#define MAGENTA "\033[35m" /* Magenta */
#define CYAN "\033[36m" /* Cyan */
#define WHITE "\033[37m" /* White */
#define BOLDBLACK "\033[1m\033[30m" /* Bold Black */
#define BOLDRED "\033[1m\033[31m" /* Bold Red */
#define BOLDGREEN "\033[1m\033[32m" /* Bold Green */
#define BOLDYELLOW "\033[1m\033[33m" /* Bold Yellow */
#define BOLDBLUE "\033[1m\033[34m" /* Bold Blue */
#define BOLDMAGENTA "\033[1m\033[35m" /* Bold Magenta */
#define BOLDCYAN "\033[1m\033[36m" /* Bold Cyan */
#define BOLDWHITE "\033[1m\033[37m" /* Bold White */
This allows you to do the following:
std::cout << RED << "hello world" << RESET << std::endl;
Note: If you don't use RESET the color will remain changed until the next time you use a color code.
