I’m writing log messages and have to do a lot like:
Logger::writeToLog (String( "This variable: ") + String (x));
That’s ugly, isn’t it?
My question, does there exist something like in python?
Or how the Norwegians do like?
QString (“A string with %1 apples” ).arg (x);
String::formatted() is discouraged and I think there is good reason for that…
Never understood why I so often see people over-using the String constructor as a wrapper around string literals… You could have just written
Logger::writeToLog ("This variable: " + String (x));
…but actually, you can do even better in a DBG statement if x is an int or double, e.g.
DBG ("This variable: " << x);
Well, the XCode complained about that, but maybe I didn’t look close enough… I thought that the + operator for const char* + String was missing… but I’ll try again…
EDIT: the variable was not a String but a const char* string, that’s why xcode complained. so I took a bad example
Seems I got a litle confused, sorry
Thanks for the DBG, didn’t know that the << operator works there. Does DBG write to the currentLogger?
Would it be an idea to overload the stream operator for Logger too, like
Logger::log() << "Something " << x;
