Invoking Python modules from Scheme

[Grant Edwards]

There seem to be a fair number of Schemers around, and I
thought you might find this interesting.  

Background: STk is a Scheme implimentation that includes
bindings to the Tk widget set, and an object system based on
tiny CLOS.

STk uses direct bindings to the Tk lib w/o Tcl, which has some
advantages and disadvantages. Scheme variables can be attached
directly to widgets without the intermediate IntVar and
StringVar stuff. The main disadvantage is that there's a lot
more work involved when the Tk library changes.

The STk home page is at:

             http://kaolin.unice.fr/STk/

Anyway, Walter Moreira has developed an interface that allows
gives STk access to Python modules/objects:

Hello.

I wrote a small interface for invoking Python's libraries from
STk. It includes a STk type that represents an arbitrary Python
object and provides a mecanism for handling Python exceptions:
a try-except block.

For example, you can do

    (define http (py-getattr "BaseHTTPServer"))

and you have the complete Python's BaseHTTPServer' module for
writing your own Scheme HTTP server.

It can be downloaded (only 25k) from
	      
  http://www.cmat.edu.uy/~walterm/spy

Please, take a look and let me know if you find it interesting.
Walter
