digitalmars.D.learn - Transforming a C/C++ project to D

I may have missed something in Google searches but…

I am looking at a GTK+2 project that was originally C, got transformed
somewhat (and a bit badly) into a mix of C and C++. I can either move it
the whole thing to C++14 or try to turn it into a D code. Revolutionary
change is likely out of the question simply because it is a bigish
project and too big an "elephant task". If however it is possible to
incrementally move parts of the whole to D that is much more likely to
happen.

Has any done this incremental move type thing before and had success?

Thanks.

Sure, it should be possible to incrementally move a project from C to D. 
It depends a bit on how the project structure looks like, but you should 
be able to port object files one at the time to D. Then link it with the 
rest of the object files.

You can use Adam D. Ruppe's tool dtoh, currently being reviewed [1], to 
create C bindings for D code. You can also use DStep [2] to create D 
bindings for the C code.

For the rest of us who do not use Tango, will DStep ever offer an option 
for use with just the phobos?

No, not unless someone else does the work. Although I don't see the 
problem. Pre-compiled binaries are available or it can compile it with 
Dub, which will handle all dependencies automatically.
