digitalmars.D - HTOD: Low hanging fruit

reply "Andre" <andre s-e-a-p.de> writes:
Hi,

HTOD is not able to translate a #define if the
value is in brackets like here:

#define SQL_STILL_EXECUTING			2
#define SQL_ERROR				(-1)
#define SQL_INVALID_HANDLE			(-2)
#define SQL_NEED_DATA				99
(Example from ODBC header file sql.h)

This seems like a low hanging fruit.

Kind regards
André

htod is old and unsupported. I recommend dstep 
(https://github.com/jacob-carlborg/dstep) which is based on 
libclang and thus naturally up to date with current C state.

To be honest I'd love htod to be completely removed from
dlang.org (and possibly replaced with dstep) as it does more harm
than good.

I agree. Please send a pull request.

Thanks,

DStep doesn't currently support any preprocessor handling, except for 
some simple includes. The C interface for libclang need to be extended 
to support handling the preprocessor as well. Contributions are always 
welcome.

Does it simply ignores preprocessor tokens or actually makes 
substitutions (but there is no D-ification)? I thought it is the 
latter.

It does substitutions. I guess using libclang would be just like 
compiling with Clang but stop the process somewhere after the AST is 
created and before the code generating phase has started.

This also has the unfortunate consequences that you can only generate 
bindings for one platform.

I guess libtooling (http://clang.llvm.org/docs/LibTooling.html) would
be a better fit for a codegenerator, but it's a C++ library.

I don't see what this would give me. libclang already handles command 
line parsing. DStep handles, in addition to those specified, all flags 
that Clang handles.

What would be better is to use the Clang C++ libraries since they 
already provide all the functionality needed. Although they are not 
stable and are C++ libraries. I'm actually quite satisfied I've come 
this far without needing to change a single thing in libclang itself.

If DStep is the prefered solution would it be possible to also

To build DStep you need Tango, a couple of my libraries (mambo, dstack) 
and libclang. I plan to make it available through Dub.

libclang is available for Windows. They provide experimental binaries 
for MinGW for version 3.1 and 3.2. I have already tried to build it on 
Windows, unfortunately it fails to pass the DStep tests. I think it was 
a segfault or similar. I haven't investigated any further.

How is that going?

I just haven't done it yet. I don't think it should be any problems. 
Although I'm not too happy I need to put my two utility libraries in 
Dub. They're not ready for that yet.

Could you not use one of the pre/post build options to pull in 
the necessary github zip files? It's a bit of a hack but i think 
it could work.

Then again, you could just add a -alpha suffix to the package 
names or similar to be absolutely clear they aren't polished 
products.

Yeah, I was think doing something like that. I just haven't had the time 
yet.

I just hit some issues with Dub. I'm considering it a blocker, hopefully 
there will be a solution:
