I’m looking for a tool, regex or other magic to do some heavy code replacements.

Ideally I would be able to replace all instances of the new operator with a call to a function preserving the arguments.

What are my options?

Update:

Example:

ClassA* a = new ClassA<int>(1,2,3,4,new ClassB(1,2),"horrible");

Should transform to:

ClassA* a = FUNCTION(ClassA<int>(1,2,3,4,FUNCTION(ClassB(1,2)),"horrible"));

Where FUNCTION will do something like:

FUNCTION(...) Debug(new __VA_ARGS__, __FILE__)

A simple replace nearly does it well, it only lacks the last ).

Update:

My initial thought was to use a macro to track some additional info like __FILE__, store it in a std container and then call new. What will happen if the container calls new? How do I add __FILE__ inside an overloaded new?

    You don’t mention why you want to do this, but I do wonder whether overloading the new operator might be a better option for you.

    Why would one replace default new and delete operators?

    Edit

    The following links might also be relevant:

    It seems like this is a problem many people have tackled before. Googling for overload|override new __line__ __file__ will throw up further possibilities.
