[GNC-dev] 4.0 and C++?

Ah OK I see, I think I misunderstood originally I though the new code 
was around the corner (and I was wondering who was doing all this insane 
porting work).
The thing that seems tricky is, fixing bugs obviously must be done in C 
mostly. For new features, it's hard to separate them enough that they 
can be written as separate C++ files no?
So what needs to be done, I guess, is to go ahead and little by little 
convert every little piece of GC? Seems daunting.

We push for new code to use modern C++ (meaning C++ 11 idioms and with more emphasis on generics than OO), but not every contributor is up to writing that. *But* GnuCash is over a million lines of C code and we expect it will take many years and many development cycles to convert everything.

We also have bindings created via SWIG, and while SWIG was designed for C++ and works reasonably well with it it takes a fair amount of care to get it to work correctly. To deal with those the C++ modules we've created are wrapped in C to ease portability.
