A better LOG() macro using template metaprogramming

Question

A typical LOG() macro-based logging solution may look something like this:

#define LOG(msg) \\
    std::cout << __FILE__ << \"(\" << __LINE__ &         


        

Answer 1

I've gone through exactly the same thing. And I ended up with the same solution you've outlined, which just requires the client API to use comma instead of the insertion operator. It keeps things fairly simple, and works well enough. Highly recommended.
