Yes create a shortPrint
class with an appropriate overloaded operator. Something like this :
class shortPrint {
ostream &o;
public:
shortPrint(ostream &o) : o(o) {}
template <typename T> shortPrint &operator<<(const T &t) {
o << t << ',';
return *this;
}
// support for endl, which is not a value but a function (stream->stream)
shortPrint &operator<<(ostream& (*pf)(std::ostream&)) {
o << pf;
return *this;
}
};
That should work (basically).
To eliminate the problem of extra commas use this :
class shortPrint {
class shortPrint2{
shortPrint &s;
public:
shortPrint2(shortPrint &s) : s(s) {}
template <typename T> shortPrint2 &operator<<(const T &t) {
s.o << ',' << t ;
return *this;
}
shortPrint &operator<<(ostream& (*pf)(std::ostream&)) {
s.o << pf;
return s;
}
};
ostream &o;
shortPrint2 s2;
public:
shortPrint(ostream &o) : o(o), s2(*this) {}
template <typename T> shortPrint2 &operator<<(const T &t) {
o << t;
return s2;
}
shortPrint &operator<<(ostream& (*pf)(std::ostream&)) {
o << pf;
return *this;
}
};
