digitalmars.D.learn - Using local import path

reply O/N/S <ozan.nurettin.sueel gmail.com> writes:
Hi

Example:
I have a module called "a.b.c";
and a second module called "a.b.c.d.e";

For importing i can use
   import a.b.c;
   import a.b.c.d.e;

or with local names

   import abc = a.b.c;
   import abcde = a.b.c.d.e;

Question:

Is it possible to use something similar like following

   import abc = a.b.c;
   import abc.d.e;

which would be a combination of a local renamed and enhanced path?
I tried and it doesn't, could be a wrong using...

Thanks & Regards,
Ozan

A bit of a misunderstanding of what is going on with import and packages 
there.

In D there is no package import functionality that is implicit.
So by importing a.b.c you're importing a module, not a package.
This is key that it is a module and not a package. Because it is not 
required to expose other modules.

Now to expose symbols to the importee via imports you will use public 
import. A public import basically says, hey I know about these symbols 
provided by another module but I want it accessible with mine.

But we have a special module called package.d which when used e.g. 
a/b/c/package.d and imported as import a.b.c; which allows the emulation 
of a package importation. But remember because of public imports it does 
not have a special package symbol associated with it. Its just a plain 
old regular module.

TLDR: no you cannot do what you were thinking.

Seems like something one ought to be able to do, though. DIP time?
