I don't know if my "Atlas" library could be of assistance here. Atlas will allow you to use python and python libraries from inside pharo via a socket bridge. I am very noob when it comes to terminal but I hear that python is very popular for command line stuff especially on linux and macos where it comes included. So if you run Atlas from headless pharo it should work and give you access to full power of python, but there are a few stuff I need to add to it. Of course the disadvantage here is that you still need to know python and its libraries.��
