The code was a simulation of a parallel system with multiple services that sent messages between them, or something like that. Instead of using serviceA.send("hello",serviceB) you had something like serviceA >> "hello" >> serviceB.
I really loved that (my classmates not so much)
SinOsc b => Gain g => BiQuad f => dac;
throw exceptionC() << "error code: " << t;
I often found myself having to format error strings for exceptions, so I thought I could just do it like cout in one line. I know now this is bad for i18n strings.
throw exceptionC("error code: ", t);
Ever since perfect forwarding I've been using this pattern to get out of arrow hell:
template <typename Arg, typename...Args>
string to_string(Arg &&arg, Args &&...args) {
stringstream buf;
buf << arg;
((buf << std::forward<Args>(args)), ...);
return buf.str();
}
