Hi Tone.
I use a parser I created with help from code by Dave Cuny,
Buddy Hyleberg and others to do a fair bit of the work to wrap=20
Morfit.
It creates an include which wraps all the "define_c_func",
"define_c_proc" stuff and also creates another include with
empty functions (uses function names etc) that are the
actual wrapper functions. These have to be completed by
hand (eg peeks, pokes, atom_to_floats etc). It also "imports"
all completed functions from the previous Morfit version.
It isn't very good code (my parts, not the bits I ripped off
others!) but I will send it to you if you like. The Morfit .h file
also seems to be pretty simple to parse compared to others
I have seen.
Good luck with it.

Hi,
Yes this has been attempted before.
Look in the archives for SWIG/Euphoria by the great David Cuny!!!
SWIG is an Open Source project that is used to wrap DLL's for
a number of scripting languages (Perl and Python being the Primary =
ones??).
SWIG/Euphoria is/was David Cuny's attempt for a Euphoria version. =20
I can't remember how good it was ... it worked at some level for sure.
It would be a good starting point though and I'm sure full of =
information
for anyone attempting similar things.
I also attempted my own version when I was wrapping Allegro without =
sucess.
If you know pascal the FreePascal people have a H2PAS program which
converts C header files to pascal. Again this has limiations but =
might
prove to have useful code or ideas.=20
Once you can parse a C Header file I believe the code generation =
wouldn't
be to difficult.
Ray Smith.
