I came across this post a while back and decided to implement

My implementation:

The above conversation seemed to stop abruptly, so I went on to
assume that no one chose to champion the task.
At the time, I looked around for other conversations or
attempts at runtime reflection for D, but couldn't really find
anything. I did find the ModuleInfo/reflection stuff in
object.d, but it seemed like an effort that may have been
abandoned. Also, the above conversation seemed to suggest it
should be opt-in, which also made me wonder if the stuff in
object.d was abandoned or for a different purpose.
Looking again today, someone seems to have been working on it a
bit.. For example, MemberInfo_field and MemberInfo_function
were empty last time I checked.
So what's the current state of things?
Is anybody working on it?
Although MemberInfo_field exists, it doesn't seem to be
available from TypeInfo_Class... Is that the eventual goal?
Is there anything I can do to help get things moving?
Any comments on my implementation would be welcome as well.
(https://github.com/bitwise-github/D-Reflection)
main.d shows some general use cases, but basically, if the
reflect(T) template is used on a class,
that class, and any child types will be reflected. Recursive
reflection only propagates downward, or else it could leak
sideways and unnecessarily reflect several modules.
Most of the reflection information is available at compile
time. For example:
enum name =
reflectModule!(test).findClass("Test").findField("variable").name;
pragma(msg, name); // "variable" will be outputted.
To make a module available for runtime reflection, the
following can be used:
mixin(runtimeReflection!test);
At this point, the above example can be rewritten as:
string name =
getModuleReflection("tests.test").findClass("Test3").findField("static_variable").name;
writeln(name);
Hi, your link is not working any more and I really need your
implementation.
