Colored output in C++

Question

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,

In a more c++ way for an ANSI capable terminal, it is possible to write your own ansi stream manipulators like std::endl but for handling ansi escape code.

Code for doing so can look like this for basic raw implementation:

namespace ansi {
  template < class CharT, class Traits >
  constexpr
  std::basic_ostream< CharT, Traits > & reset( std::basic_ostream< CharT, Traits > &os )
  {
     return os << "\033[0m";
  }

  template < class CharT, class Traits >
  constexpr
  std::basic_ostream< CharT, Traits > & foreground_black( std::basic_ostream< CharT, Traits > &os )
  {
     return os << "\033[30m";
  }

  template < class CharT, class Traits >
  constexpr
  std::basic_ostream< CharT, Traits > & foreground_red( std::basic_ostream< CharT, Traits > &os )
  {
     return os << "\033[31m";
  }
  ...
 } // ansi

And it can be used in a code like this:

std::cout << ansi::foreground_red << "in red" << ansi::reset << std::endl;
