August 05, 2021 Generating C Headers From D Code | ||||
|---|---|---|---|---|
| ||||
 | I need to generate plain C99 .h files from a D module's extern(C) declarations, so that I can link a DMD generated .o file with a C code base. Are there any automated tools which do this? I know the compiler has C++ header generation, and there's tons of tools which exist for importing C headers into D code. I'm not aware of anything which goes the other direction. Google wasn't much help either. | |||

I also can't find anything... until someone else comes with a better answer, maybe you can do this: Use the Remove all the Rename the file extension from Technically, it should work. Hopefully someone else knows better. | |||

Hopefully someone else knows better. Well, that's disappointing. I suppose everyone just makes there main file a D file when converting C projects so they don't have this problem. Eventually I'll have to write a script which takes .di files and generates .h files, but doing it manually will have to work for now. | |||

Your best bet is probably to use this and just do the slight modifications to turn it from C++ into C.
dmd -HC
followed by a modification script to rip some of the stuff out might get you somewhere.
A long time ago i made a program called dtoh that did it from the generated json but like i think that broke years ago, i haven't touched it for ages. can't find it anymore. dmd -HC surely better anyway.
