digitalmars.D - private declaration in module

Hello. Can you help me? Newbie question:
how i can hide come functions and other declarations in my D module from import?

I want declare one or more public function in module (so other modules can use
it), and one or more private (local) functions (for internal usage only, so
other modules can't use it directly).

Thanks.

Very simple, all protection attributes are module based (within a class, 
a struct, a template or without) with the exception to protected.

package		= The module and submodules may access it
private		= Only the module may access it
protected	= Only within classes and interfaces, only subclasses
		  may access it
public		= Every module may access it

Also:

import		= Imported modules are visible to other modules using
		  your module
private import	= Imported modules are hidden for other modules using
		  your module

Regards,
Sjoerd

See protection attributes in
http://www.digitalmars.com/d/attribute.html.

#module mypackage.mymodule;



#package {






#private {





You're welcome,

May be, my question cause is my bad english. At
http://www.digitalmars.com/d/attribute.html
"private" described as applied to "enclosed class" only,
but my program has no classes.


Private means that only members of the enclosing class can access the member,
or members and functions in the same module as the enclosing class. Private
members cannot be overridden. Private module members are equivalent to static
declarations in C programs

Private can be used at the module level too.

     module foo;

     private int helper() { ... }

     int somethingInteresting() { ... }

It is not your english, that sentence is misleading. I think "enclosing 
class" should read something like "enclosing class, enclosing template 
or enclosing module, whatever comes first".

Some word-smithing wouldn't hurt, but note it does say "Private module
members are equivalent to static ..." so it does address what private means
for module-level declarations.
