Hello,
so what are my / our best options to create an automatic C 
foreign function interface.

I would like to create such interface / header file from a D 
module with public functions, structs which are declared with 
extern(C)

D code

module leo

extern(C) void test() { }

Expectation:

// header file
void leo_test(void);

Try ImportC its built into the compiler.

You can use the .di generator to emit a D file for further use and 
manual cleanup.

It does depend upon the system toolchain, so you'll want MSVC installed 
if you use Windows.

Hello Richard,

Thank you for the info. I thought this goes the other way around. 
Using a header file and converting it to a .di file.

I want to create a .h file from my D modules so you’re saying 
this should be also possible ?
