Hello, world. Brand new poster here though I posted similar
messages in other language forums. I hope this is the right place
to ask because my question is half about existing stuff and half
about prospective work.
I am considering starting with D amid a C++ code base. New D code
would need to somehow integrate with the existing C++ code. The
C++ code is the expected melange of free functions, classes, what
have you and uses STL and Boost (also other libs less
prominently). Allow me to ask:
1. What is the current support for calling C/C++ free functions
from D? What level of mangling is supported? What data types can
be passed without translation from D to C/C++?
2. How about template functions? Is it possible to call a C++
template function from D?
3. How can a C++ object be used from D? Can C++ methods be called
from D? The question applies to value types - no virtuals - and
polymorphic types with virtuals, inheritance etc. And of course
simple C structs.
4. How about template objects? One issue is that many C++
interfaces pass std::string and std::map<..., ...> as parameters.
How feasible is to manipulate such objects in D?
5. How about the other way? Can a C/C++ function call a D
function?
I would appreciate any pointers you have to how-to materials. In
equal measure I am interested in plans to address such issues in
the foreseeable future. Thankyou.
