Hi,
I'm using structs to describe my functions:

@example(example1, 1)
void myFunction()
{
// do something
}

module mod.example2;

@example(example2, 2)
void myFunction()
{
// do something
}

I'm using the struct to describe functions in different 
modules. Now, I want add all functions which are described 
using the example-struct to an array during compile time. But 
how can I do this? I know, I can use __trait(allMembers, 
mod.example1) and __trait(allMembers, mod.example2), but I 
only want specify the parent module (mod), for instance:


void main()
{
  foreach (member, __traits(allMembers, mod))
  {
 writeln(member);
  }
}

But this only shows object - nothing else. No sub-modules 
like mod.example1 or mod.example2. So, how can I find all 
functions that are described using my structure during compile 
time and add them to an array?


I already tried this:

void main()
{
  foreach (cmodule; ModuleInfo)
  {
 foreach (submodule; __traits(allMembers, cmodule))
 {
 // ... also tried: foreach (submodule; 
__traits(allMembers, mixin(cmodule.name))), cmodule.name is 
not available during compile time...

 }
  }
}

But it always stats that 'cmodule' has no members. Does anyone 
know how to solve the problem?


perhaps you could get somewhere by using a package.d in every 
package?


If it needs to work on packages you don't control then I don't 
really know :/


Hm, importing the package doesn't help :(
Okay, I see... I've to solve the problem using another idea...

there is no non-hackish solution, afaik. there is no even hackish, but
reliable one.
