I wanted to have a look at the dmd frontend so ended up checking out
this (dmdfe).
It was 0.121 and I found dflect as well which was 0.126.

I grabbed dflect which is almost the same as dmdfe, except it generates some runtime reflection code (which I have not tested, but the app runs and generates some output).

dmdfe wise: Except for the Module::genobjfile they are all still stubs.

The upgrade to 0.176 was actually pretty easy, so I might have missed something, but it compiles...

Hope somebody will find this useful.

Hi Tomas,
please explain the sense and possible practical use of your dflect
implementation.
 I guess it is in Cpp so why the  brave D Developer should spend time in
investigating this software ?
(Could be a matter of interrest if Stubs have a DLL interface)

In case that I pick on your nerves ...Not my intention!! Just wonder .. Bjoern

I personally wanted to see how the DMD frontend worked.
The dflect stuff is just because dflect used dmdfe and was a newer
version of DMD than dmdfe.

If someone wishes to do something with the DMD frontend, then this project could be helpful in getting started faster...

Reason I looked into it was to learn more about compilers - something I have never investigated before. I've also been reading the LLVM docs for a while since there was a post about it.

Who knows, if I keep finding this interesting enough I might use the code I just posted as a base for making a LLVM based D compiler.

I found it much easier to figure out (somewhat) what is going on in DMD using this compared to the raw DMD, as I can actually compile this an get an app with a DMD commandline interface.

In other words. The DMD frontend from the dmd zips doesn't compile out of the box. This does*...

Hmmmm,
Tomas  Having fun in finding a special solution for a special problem is
pretty okay, but who can participate and enjoy in this case?
Still, where is the pragmatic : This is good for ....

Ben Hinkle who originally made it describes it like this:

"The dmdfe program consists of the Digital Mars D compiler frontend with the backend hooks stubbed out. The goal is to make it easy to write tools that can parse and do basic semantics analysis on D code."

That's really all there is to it. It *might* be useless for real world stuff, but I found it interesting none the less. Someone else might as well - which is why I decided to announce it.
