Hello all,

I'm considering creating some D bindings for a C library.  Before 
I start, I was wondering if anyone could advise me on the current 
state-of-the-art in automatically converting C headers to .d or 
.di files; it's a long time since I've looked at anything to do 
with this and the interfacing-with-C page in the D reference 
doesn't mention any tools.

Thanks in advance for any advice,

Best wishes,

     -- Joe

I should probably clarify that I know what to do assuming I have 
to write all the bindings manually.  However, as the library has 
quite a lot of header files, I'd really much rather auto-convert 
as much as possible, hence the questions above :-)

There are some binding generator the most two famous being htod 
and dstep:

Is htod maintained any more?  I had the impression it had kind of 
fallen by the wayside.

I'll give dstep a go, though. Thanks!

Cool, thanks.  The stuff about using c_long and c_ulong is 
particularly useful/relevant to my use-case, so it's good to be 
reminded of that.

Hi Joseph,

How's things in Berlin? :-) I'm not sure how complex the C-Api 
you're wrapping is, but I have to say I found that writing a 
minimal (but complete) subset of an existing C-API to be quite 
straightforward and enjoyable. A plus point was that selecting 
only the useful minimal subset meant the D wrapper ended up being 
a lot cleaner and meant that unused (or undesirable) features 
simply weren't there in the wrapped API.

YMMV but it's one to bear in mind...

Cheers,

A.

PS - I forgot to insert the words 'by hand' in there somewhere. 
Also for additional guidance aldacron has some good blog posts on 
the wrapping process on the web somewhere. I pretty much used his 
guidance when I started my experiments with wrapping and have to 
say I was pretty satisfied with the end results :-)
