digitalmars.D - DMD git HEAD now self-hosting

I'm surprised nobody has mentioned this on the forum yet, but as of 23
Aug, dmd git HEAD has switched over to ddmd with the landmark commit
88ec9d8.  Since that time, the remaining C++ files have been slowly but
surely phased out one by one, replaced with their D equivalents.

This is awesome news!!!! I think a celebration is in order. ;-)

As of today, there are still about 28 or so C++ files left (84 source
files are now in D). PRs converting C++ sources to D continue to trickle
in.

Way to go, D!

The DMC backend is still in C++, although Daniel is planning to 
convert it to D too.

Ahh, just realized I'm not subscribed to the announce mailing list.

So.. looking through the source, I see lots of this:

extern (C++) class { ... }

Wasn't extern(C++) only supposed to work on interfaces?
Are the docs outdated?

Thanks,

Yup.  extern(C++) works with almost everything except special member 
functions.

We've been celebrating without you on the announce list!

Unfortunately it's going to slow down for a little while.  The files I've 
done post-switch were only left in C++ because they used a small part of the 
backend headers and were easier to do by hand instead of converting 
automatically.  The rest of the glue layer/backend (~90 c++ files) is going 
to need a conversion project of the same scale as the frontend one, preceded 
by a refactoring project 10 times the size of the frontend one.

Walter's recent backend cleanup PRs are working on this, and I'm working on 
a backend test suite to make refactoring safer.

We could see DMD be 100% D within six months, depending on how much free 
time I have and how picky Walter is about my refactoring PRs.

6 months isn't that long of a time. Excited to hear that 100% D DMD will
soon arrive.

Another thing I just realized, is that by moving DMD to D, we've given
ourselves much greater motivation to improve DMD's codegen, which I
think is a good (and necessary!) thing, being the reference compiler and
all. Not every newbie will understand the current situation where the
reference compiler doesn't produce the most performant code.

And the other advantage is that we'll get performant code with a 
performant compiler - GDC/LDC are much slower running than DMD.
