9.2. Namespaces

Namespaces are containers of functions, macros and pseudocommands. There can only be one of each of these entities in namespace. Every namespace also have an its own associated scope so each time you define a namespace a scopes is automatically defined.

A simple way to declare a namespace is shown in the following example. The namespace directives is covered in more detail later (and often the .filenamespace directive is more handy): 

.function myFunction() { .return 1 }
label1:
.namespace mySpace {
   .function myFunction() { .return 1 } // <- This won't collide
   label1:  <- This won't collide
}

Namespace can be declared more than once. The second time you declare it, it will simply continue with the already existing namespace. 

.namespace repeatedSpace {
   endless: jmp *
   .function myFunc() { return 1}
}

.namespace repeatedSpace { // <- Don't give an error, we reuse the namespace
   jmp endless
   .function myFunc() { return 2} // <-- This gives an error, myFunc is already defined
}

If you are in doubt of which namespace you are in, you can get its name by the 'getNamespace()' function. 

.print "Namespace = "+getNamespace()
.namespace MySpace {
   .print "Namespace = "+getNamespace()
   .namespace MySubSpace {
      .print "Namespace = "+getNamespace()
   }
}

The above will output:

  Namespace = <RootNS>
  Namespace = MySpace
  Namespace = MySpace.MySubSpace
