Hello guys,
so how do we generate C header files automatically for a
library compiled with dmd, ldc
in betterC. Like basic example below. I found the "-HC" flag
which can be used to output C++ header files. Do I need to
convert those manually to C?
```D
export extern(C) {
uint add(uint a, uint b) {
return a + b;
}
}
```
dmd -c mycode.c -Hf=mycode.di
```
https://dlang.org/spec/importc.html#ctod
If you want to output the function bodies as D code, add
`-inline`:
```
dmd -c mycode.c -inline -Hf=mycode.di
```
Oh sorry. I think you mean you are compiling D code to be
called from C.
Thank you for your answer. Yes I am going the other way. I create
the lib in D and want to create a C header and other bindings. It
should be a lib usable from many other languages like raylib but
with the power of D!
I have looked into __traits and I guess i need to go this way.
The perfect way would be to get a XML or json from the functions
so that the bindings can be easily automated
