Hello,

I am pleased to announce the release of G-Wrap 1.9.0. The release is
available from

          http://savannah.nongnu.org/download/g-wrap/

G-Wrap is a tool (and Guile library) for generating function wrappers
for inter-language calls. It currently only supports generating Guile
wrappers for C functions.

G-Wrap 1.9 is a more-or-less complete rewrite of the 1.3
codebase. Currently, wrapsets written for 1.3 are incompatible with
1.9, due to the big architectural changes. A compatibility layer is
planned, however. Compared to G-Wrap 1.3.4, the following features
have been added:

* Glueless wrapping

  G-Wrap can now create function wrappers dynamically via libffi. This
  means that in most cases, G-Wrap doesn't need to emit a C wrapper
  function, thus reducing emitted code size considerably.

* Output arguments

  Now functions such with output arguments like

      void getxy(int *x, int *y);

  can be wrapped sensibly; using let-values from SRFI 11, you can use
  the generated wrapper function like this:

  (let-values (((x y) (getxy)))
    ...)

* Default arguments

  It is possible to specificy default arguments for a wrapped C
  function. Calls to the resulting wrapper function may leave these
  arguments out, causing the default values to be used.

Regards,
        Andy

To iterate is human; to recurse, divine.
