Yes , I was aware of the excellent work of kilon. I was hoping that this be the way to solve my issue.
Thanks kilon, I will follow your instructions and comment the results into the list. Ing.

So as Ben said I am the author of Ephestos, a communication bridge between Blender and Pharo . To go directly to the how to . Ephestos is basically a socket bridge that send via sockets strings from pharo to python that then python executes as python commands. Ephestos is made so it works inside blender but I promised Atals a spin off project that allows the same socket bridge to be used as a standalone. To use do the following. 1) Get Ephestos , you can find it and install it with the configuration browser in your image in Pharo 3 and Pharo 4. Make sure you have a recent release though because I added it recently. 2) Get pyAtlas , this is the python side , you can get it from here --> https://github.com/kilon/pyAtlas 3) in your command line cd to the pyAtlas directory and execute : python3 pyAtlas.py 4) in Pharo you can now try any python code you want for example Ephestos sendMessage: 'print("hello world")'. Ephestos sendMessage: 'x = 3'. x := Ephestos getValue: 'x'. x inspect. Ephestos sendMessage: string, basically sends the python command to be executes while getValue: sends the command and returns a value as a string. you can use string 'exit' to close the socket bridge but this part is buggy as it seems to keep the binding of the sokcet active and I have to wait to clean it up in macos to reopen the bridge. You can also use pharo syntax and python errors will trigger the pharo debugger with a title the python error itself. You can find more information about Ephestos in my gitbook that can be read here https://www.gitbook.io/book/kilon/ephestos Also I forgot to add that sendMessage can send multiline strings , so its possible to send python class definitions and other stuff, you type the string exactly as you would type python code respecting whitespaces. If you want to execute loads of lines of python code then it would be better to put your code in a python module and do Ephestos sendMessage: 'import mymodule' assuming your module is called 'mymodule' , python import basically are executions of code. If you have any questions just ask. Bare in mind this is a socket bridge so its not ideal for sending thousands of messages per second and you may run into the occasional bug or two which I will fix if you report it. Nonetheless it should allow you to execute any kind of code and not just call python functions or python methods.
