digitalmars.D - htod feature request: save commands in translated file

reply Andrej Mitrovic <andrej.mitrovich none.com> writes:
I don't know where else to put this topic. Currently htod translates a C/CPP
header file to D and adds a line at the top such as:

/* Converted to D from someheaderfile.h by htod */

The Bindings project relies heavily on htod, but the problem is: when a new
version of a library comes out you're left wondering which commands were used
with htod to translate the header files.

So the feature request is, if I specify some commands to htod, such as:

htod cheader.h dimport.d -cpp -hc -hi

then htod should put those commands in the resulting file as a comment, e.g.:

/* Converted to D from someheaderfile.h by htod */
/* using arguments: -cpp -hc -hi */

Whaddya think?

It's useful, as would be the addition "on 2010/10/17 at 20:38:50 CST" 
and the htod version used.

Here's one failed conversion from 5 minutes ago:

C:
typedef	struct SNDFILE_tag	SNDFILE ;

htod:
alias SNDFILE_tag SNDFILE;

This should be:
struct SNDFILE_tag {}
alias SNDFILE_tag SNDFILE;

But I guess that's a rare and dubious case.

I think it should rather be

struct SNDFILE_tag; // forward declaration
alias SNDFILE_tag SNDFILE;

You can't define a struct that have no idea about, its proper definition  
may follow any time.

Hmm.. okay. I copied those from a pretranslated .d file I found
googling. Otherwise, SNDFILE is internal to the library and I
shouldn't mess around with it except send and receive it via function
calls.

What about http://github.com/klickverbot/swig/commits/swigd (Swig4D)
to create D-bindings for C-libs?

That's probably because I haven't officially announced it yet – I am 
currently trying to get it into SWIG trunk. After this is done (which 
could take quite some time, since I have not received a real response to 
my post at the SWIG mailing list yet), I will also try to get all other 
SWIG-related pages marked as obsolete to avoid confusion.

At the moment, you can simply contact me via mail if you hit any bugs or 
have any related questions.

And today I went and skimmed over Swig's docs...Boy, it has improved a
LOT since I was looking at it some years ago.

It seems I can tweak D-side of the interface to bring some type-safety
to the bindings (something I was accustomed to while being in Haskell
world where one can tailor Haskell side of the data and have types
checked at compile time).

Otoh, it would be nice if someone could clear this stalled data on
dsource.org which just helps spreading FUD about D.
