Integrating another library in squaeak

Hi all,
I have some beautilful libraries written in python and i want to call them from smalltalk. It would be great to make this "integration" platform independent. What is the way that i can follow? (in windows i think i can make a COM server, but i prefer a general solution, if possible :) )

thanks,
nelson

Hi!

I missed the post below in my other answer so:

Well, you could try making a "python plugin" that embeds the Pythin
interpreter in a plugin. See more details at:

http://www.python.org/doc/faq/extending

But this is not a simple thing to do, you need to dabble around in C and
learn the voodoo of plugin making, even though there are several
examples to look at.

A simpler approach with much worse performance (but it might not be a
problem for you) is to simply try using SOAP.

There are probably more ways to do it too.

I think to SOAP too. My library has to process some big dataset for datamining, so the performance wouldn't be a problem. On the other hand, if i can interface directly from python it would be cleaner...

There are probably more ways to do it too.

Right! Another unconventional and probably faster way to connect from
Squeak to Python via sockets would be to use OSC.

Thank Marcus for your answer. I see OSC, but it seems too linked to sound applications :) I want to control from Squeak a remote object written in Python, that's my goal :)

That's what it says - but it is a misnomer in my humble opinion.

What it does is to provide an easy to use interface to send some messages with integers, strings, symbols, floats etc from one OSC-enabled application to another, be it on the same computer or somewhere else.

I cannot find anything sound related in the specification of OSC:

http://www.cnmat.berkeley.edu/OpenSoundControl/OSC-spec.html

Guess the skepticism stems from the fact that "udp does not provide the reliability and ordering guarantees that tcp does", which makes it certainly more suitable for media streaming than for power plant controlling. ;-)

- Right now the squeak-version is based on udp but it would be easy to change it to tcp.

Conclusion

If you really considered Soap, you might as well consider OSC.

Advantage: Probably faster than Soap

Disadvantage: You might have to enable both OSC implementations on Squeak and Python using tcp, if you wanted to be on the "100%" sure side.

Markus
