Actually, most of porting SWIG would be about C/C++ coding.
It creates
C/C++ wrappers for all the functions -- quite different from
what Brad
has done so far, for example -- which accept language
objects and call
the underlying function. It could actually be faster if we
had a
primitive to do a C call directly, with no interpretation in
cint.c.
While I was working on speeding up C call-outs, I just added
a small
feature. If you declare a method with <cCall:
'function'> (i.e. no
returning: or args: keywords), it is the same as passing all
the
arguments as #smalltalk, plus (if the method is on the
instance side)
passing the receiver as #selfSmalltalk. This would be the
calling
convention that SWIG needs, and the new syntax (which is
only a shortcut
so far) might be transformed to a primitive if the SWIG plan
materialized.
