It would be v helpful to have a Datetime conversion from D.
Looks like there is a macro for converting from ymd in
datetime.h, so I guess one could just write some code against
this API in C, D, or Cython and link it in with D so one can
transfer data structures over more easily.
I know just enough about that topic to be very scared.
I should be able to call these from D without changing PyD, I
think, for D to Python. Not sure about Python to D, but maybe.

Doh!
It's already in deimos, but you need to call PyDateTime_IMPORT();
before calling the conversion function.
So all that is needed is the following:
module example;
import std.datetime;
import std.stdio;
import pyd.pyd;
import std.conv;
import deimos.python.datetime;
DateTime foo()
{
return DateTime(1999,1,1);
}
extern(C) void PydMain() {
ex_d_to_python((DateTime dt) =>
PyDateTime_FromDateAndTime(dt.year,dt.month,dt.day,dt.hour,dt.minute,cast(int)dt.second,0));
def!foo();
module_init();
PyDateTime_IMPORT();
}
Ideally, shouldn't PyD do this for you ? I think the code is
already there in make_object.d, but it doesn't work - maybe
because PyDateTime_IMPORT() has not been called if it needs to be.
Thanks.
Laeeth.
