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.
