C++ Embeded GOOPS interpreter

C++ Embeded GOOPS interpreter

[Laurent Marzullo]

Hello,

I would like to write a C++ Application which will use a GOOPS
interpreter.

The C++ application will provide a set of class that could
be used in a scheme programme.

For example, I would like to provide:

class MyClass
{
    public:
        MyClass( int p );
        void SayHello( void );

    private:
        int   m_private;
};

(Perhaps the class above could be seen as:
(define-class <MyClass> ()
    (p #:init-value 0))


and to be able to write in scheme:

(define my_object (make <MyClass> #:p 5 ))

I've take a look at SWIG to generate wrapper function etc, but
it does not use GOOPS even with -c++ option ?
Is there any doc where I could find information of how to write C++
code to provide C++ class access in scheme ?

Thanks

I've written something like this, although it depends on Guile 1.7
(CVS) (but it should be easy to get it running with 1.6) and still has
quite some bugs. See
http://ucxx.sourceforge.net/docs/manual/ch01s02.html#id2816562. I
recommend you try the CVS version. Even if you don't really use Yehia,
it's code (esp. the stuff in
http://cvs.sourceforge.net/viewcvs.py/ucxx/yehia/plugins/guile/)
should be useful for ypur purposes. Feel free to ask me if you need
help wrt. Yehia.


HTH & Regards, Andy

GOOPS support is currently being added to SWIG by John Lenz (for
inclusion into SWIG 1.3.20).  Some code has already been checked into
CVS SWIG; check if it is already good enough for your work.
