Hi Alexandre, I know about the bridge you did. I think I prefer to embed python runtime into VM process. Will see, if that won't work, will give it a go. Thanks! Jan On Thu, 2020-01-02 at 14:22 +0100, Alexandre Bergel wrote:

Hi Jan,

We worked hard on PythonBridge, a bridge between Smalltalk and Python. Our bridge uses a sophisticated messaging and queuing mechanism to enable debugging and traceability of the interaction between Python and Smalltalk. And yes, if a Python proxy object is garbaged collected within Smalltalk, the corresponding python object will be garbage collected within Python on some point.

We made a short video about this effort: https://youtu.be/uKSHUVZs75k

Our bridge works for Pharo and VisualWorks. It should be easy to port it to another smalltalk. Some links: https://objectprofile.github.io/PythonBridge/ https://github.com/ObjectProfile/PythonBridge

We use the bridge to enjoy AI and image processing python libraries within Pharo and VisualWorks.

And thanks Lam Research to make all this happen.

Cheers, Alexandre

Hi there,

does anyone know how OpenQwaq's Python bridge was/is implemented? Does it use a VM plugin/ffi to interact with Python runtime?

If yes, does anyone know if sources are available (under some usable license)?

If so, where can I find them? My google-fu failed me, as usual.

All the best in 2020!

Jan
