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.

I was thinking that it could be possible to make a program which would =
automatically wrap a dll. It would have .dll and .h file for input, or =
maybe just .h file, and output would be one big .ew file. It =
could/should also handle strings and structures. My WinMania library =
could be automatically generated without any work (hand editing) with =
such program. This is definiteley something that will/should probalby be =
done sometimes for Eu. euAllegro library could also be generated with =
such program. It would be like C to Eu translator, but only for =
functions in dlls. This would be a challenging task for someone to do. =
It would basically be a parser (very powerful, like a C compiler almost) =
for .h files. Then it would be using C libraries in Euphoria very easy, =
you would just generate appropriate .ew file for a dll and you could use =
it like in C but with Euphoria language. Anybody knows of any limits why =
this couldn't be done, anybody thought of this before?
