Hello,
Why don't You make htod opensource? I don't think it has commercial potenti=
al,=20
or I'm wrong? I'm asking, because it's a shame that people who wants publis=
h D=20
bindings have to make their own scripts for that (so bindings can be genera=
ted=20
on !windows too).
If there are no chances for getting htod, maybe someone know decent binding=
=20
generators (scripting languages preferred)? The ones, which I've been using=
=20
are too bad (i.e. stripping out const from various places).

Cheers,

If I remember well, Walter said it includes parts of his C++ compiler 
(DMC), which he sells, is closed source, and has a long history. It's 
possible he does not have the right to license it as open source, or 
perhaps he just doesn't want to disclose the source for DMC.

You can buy the source to DMC!

htod is built out of the C and C++ compiler front end, the source of which 
Digital Mars sells.

 Thanks, I understand that. Why htod strips out const?
 1)
 in: const int var = 2;
 out: null
 
 2)
 in: DLL const char *func( int arg );
 out: char * func(int arg);
 
 3)
 in: DLL void func( int arg, const char *arg2 );
 out: void  func(int arg, const char *arg2);
 
 4) there is
 const int * const
 and void func() const
 too, of course
 
 a) Are there any chances to fix it?
 b) If no, someone of You have seen tool that implements const's properly? (as 
 I said, scripting language would be preferred, but anything appreciated)



htod was built for D1, and hasn't been updated for D2. Hence, there are some 
issues. But it cannot work perfectly, there'll usually be a bit of hand editing 
of the result.

I'm working on a tool that creates bindings for Objective-C which of 
course have to work for plain C as well. It's built using the Clang 
libraries (it really helps having a complete frontend) and would work on 
any platforms supported by Clang. Even if Clang's support for Windows my 
not be complete I think it's enough for this tool, I mean it doesn't 
generate any binaries.

Well, Clang can build binaries on Windows. AFAIK the only problem is
exceptions on Windows.
