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

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.

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!
