This is not so easy in C. In Java you can use the BSF which allows java to
expose internal objects to a large number of different langauges. The
in C is that each of these scripting languages has a different way of
C objects. Looking at the python stuff there is no way this would work for
The problem is marshalling data from one language to the other. In order to
this work for all langauges you would end up writing a generic scripting
which knew how to marhall PD data into each separate languge probably using
sort of intermediate representation- not something I am wanting to do right
(or ever for that matter). The only way I can think to make it available to
languagues is to use COM (windows only) or CORBA (serious serious serious)
Making a Java scripting engine would be trivial (well it would to me - I
with Java most of the time at work) and possibly more cross platform and you
then but leap frog into other languages via BSF but you are adding layer
of translation and perfomance will be going rapidly downhill at this point.
I also feel that python has more relvant scripting type stuff in it and
would be quite
interesting in conjunction with PD.
