Hello,

suppose you have the following template:

| template Foo (alias X)
| {
|   const char[] Foo = X.stringof ~ " = null;";
| }

... and instanciate it with a struct member ...

| mixin (Foo !(mystruct.member));

... this code becomes "member = null;", although I'd like it to be
"mystruct.member = null;" Is this intended behavior? .stringof seems to return
only sort of a short version of the name.

Of course I could make my template accept a string "mystruct.member" instead of
an alias to make it work, but I thought this would be more comfortable to let
the user call my mixins with variables instead of strings, containing
variables! Or is there another way to achieve my needs?

best regards
Matthias Walter

You can use the meta library in Pyd.

http://www.dsource.org/projects/pyd/browser/trunk/infrastructure/meta



struct foo
{
   int bar;
}

pragma(msg, qualifiednameof!(foo.bar)); // prints somemodule.foo.bar
