How do I refer the current namespace while declaring it? Is there any word like "self"/"this"?

Question

Here if I rename the namespace I must also remember to look at the rest of the code, and do all necessary changes. Is there any word like self, this or current to refer to current namespace?

namespace myNamespace {
  int myInt;
  void myFunc() {
    myNamespace::myInt = 66;
  }
};

Answer 1

Why are you reffering to your current namespace? there is no need to for that, you can easily write:

namespace myNamespace {   int myInt = 33;   void myFunc() {     myInt = 33;   } }; 

No matter what variables are declared out there (such as a global myInt), variables of this scope will be used by default.

However if you want to rename, you can use IDE techniques like replace or refactor.

No, there isn't, but if you really want to do something like that you could fake it.

namespace myNamespace {   namespace _ns = ::myNamespace;   int myInt;   void myFunc() {     _ns::myInt = 66;   } } 

If you change myNamespace, you need only change _ns to match it.

Also, the semicolon following the namespace is superfluous.

Good question. No, there is nothing like this.

Furthermore, pay attention that myNamespace::myInt isn’t even unambiguous in the case of nested namespaces (say you’ve got the convoluted case of namespace myNamespace { namespace myNamespace { … } }. To be on the safe side you need to use the fully qualified namespace:

::myNamespace::myInt = 33;

Where the prefixed :: refers to the global namespace.
