Hello!
We have a need to bind smaller to medium-size C library and would like
to provide more D-ish or higher-level bindings than just wrapper over C
code.
E.g. the C function looks like:
int swe_calc_ut ( double tjd_ut, int ipl, int iflag, double* xx, char* serr)
and we would like to e.g. use exception to handle errors instead of
checking return value and fill 'char* serr' or store the result of
6-field 'double* xx' array in some data structure etc.
Afaics, htod is more suitable for just wrapping C code, so I wonder if
there is something else you can recommend besides SWIG?
Sincerely,
Gour
I'm finishing a fast (I just don't see a faster way) and garbage-free
CTFE-capable wrapper. But it requires IDL to be written for every C
function.
It already performs C-arrays (with length or end element) to D arrays
conversion and UTF-8/16/32 conversion (usable for WinAPI *W functions).
It will soon wrap functions like `GetCurrentDirectoryW` where it will
call C function twice (if it will not guess with buffer size at first time).

For easy understanding of how does it work look at `examples/c.d` - this
is a bunch of test C sources. D sources obtained from it are in `out`
directory.
