I want to access the type of the enclosing struct in in a shared static initializer.. How do I do that? The following code will not compile:

mixin template MsgMixin(T ...) {
  static string getName(this M)() {
    return M.stringof;
  }
  shared static this() {
    import std.stdio;
    writeln("register " ~ getName());
  }
}

struct MsgTestMsg {
  mixin MsgMixin!();
}

I get the following error messages:

src/main.d(40): Error: template main.MsgTestMsg.MsgMixin!().getName does not match any function template declaration
src/main.d(40): Error: template main.MsgTestMsg.MsgMixin!().getName(this M) cannot deduce template function from argument types !()()

If not possible, just getting the name of the enclosing struct would help a lot!

typeof(this).stringof

This should do it

use typeof(this), eg:

mixin template MsgMixin(T ...) {
    shared static this() {
        import std.stdio;
        writeln("register " ~ typeof(this).stringof);
    }
}

Thanks a lot both of you. The code below worked. I did not expect 'this' to be available in the static function, but of course the type of 'this' is available.
