Ok, enough BS...
So here is my personal tool for generating extern(C)/extern(C++) bindings[1].
I know there is several other tools exists, but this one is mine.
Currently it is in early pre-pre-pre-alpha stage, and is probably doesn't even work on any somewhat serious codebase. Might not work on Linux, or Mac, or just any non-Windows 10 OS.
There is example output in the repo, and the list of current features and known issues.

So what it can actually do?
Might work to do C conversion without manual editing, but in practice C stuff use a lot of defines as constants, so you will have to find them and write by hand, not convenient, true.
Might work with basic C++ headers without much of templates/inlines/defines-as-constants

Give it a try and let me know if you find something that is not on the limitations list, I will add it to the list, and everyone will be happy again!


p.s. no, it is not belongs to the announce group, as the tool itself is still far away from being truly useful, but it might accelerate your binding making process as well, for example making bulk of code output and then manually adjust some stuff once per month isn't that much effort comparing to doing everything by hand, not even mentioning doing it on per month basis...

Try this https://1drv.ms/u/s!AgMDJgyotPu6ljpA5_GwX898gAcg
It is x64 debug build without PDB.
But from my experience it will not work due to debug C++ runtime being used. At least not without VS 2017 installed.

How does it compare to dstep?

Based on clang? I approve.  I'll have to try it out sometime.

To be honest I don't know. Also dstep is written in D and using only 'stable' clang C API, right?
This tool is based on full 'unstable' C++ API, so in theory it is possible to do broader range of features, such as template substitution for wrapper generating (or just writting .cpp file for compiler to generate actual code).
If you asking about actual C/C++ support I have no idea, also dstep is probably can do Objective-C as well (but not this tool), and on average at this moment dstep probably has better C support.

Recently there is also "dpp" showed up, it also seems to do same C API approach as dstep, probably has little-to-none C++ support, might be wrong though. Oh wait, no Windows? nice... But if you only ever do linux stuff and C only then it probably even better choice.

There is also Calypso (which I assume won't work on Windows as well), that probably should just work with anything you throw in. But this approach has one small downside - no autocompletion and syntax checking.

To be precise it is based on clang libtooling API, and not the clang itself, it does not implements or extends the compiler, but uses its reach API's for handle stuff.

Sorry for a poor misleading wording.

Yes.

So far I haven't had the need for the C++ API. But DStep doesn't support generating bindings for C++ yet so...

Yes, it can do Objective-C, but not C++ (yet).

DStep works on Windows these days (compiler from master).

Somebody managed to get dpp compiling on Windows. It's not going to be a lot of work to get it done, it's just not a priority of mine.

C++ support is getting there. On Monday I wrote the line `#include <vector>`. It didn't work, but the fact that I even attempted is major progress.

C++ is *massive*. And `<vector>` #includes `<type_traits>` which uses pretty much every advanced template feature ever.
