Welcome to the Better Enums tutorials! The code in this tutorial forms a valid program, which you can download and play with. The program runs as part of the automated test suite.

Stream operators

These work almost as you'd expect. First, make sure you include iostream before enum.h in any translation unit in which you intend to use the operators:

#include <iostream>
#include <enum.h>

BETTER_ENUM(Channel, int, Red, Green, Blue)

int main()
    std::cout << +Channel::Red << std::endl;
    return 0;

The thing to watch for is the +: without it, Channel::Red is a value of type Channel::_enumerated, a C++98 enum type, so writing that to cout will output an integer. +Channel::Red, however, is a value of type Channel, and writing that instead will output the string "Red".

Input is also supported:

Channel     channel = Channel::Blue;
std::cin >> channel;    // Expects input such as "Green".

Only char streams are supported for the time being.
