Thank you! Yes, the situation here is very severe, especially being in the red zone. Luckily, my family has not been affected by the virus, yet. We are all following the laws and we are staying at home as much as possible. I should also publicly thank the team of opensource.com, that showed me their sympathy in some private conversations. They do care about the authors of this platform.

Thank you also for your kind words about this piece. I am doing my best to give back to the community, for all the software I have used to far.

Yes SWIG is a valid alternative, which for this simple situation could certainly be more practical.
Frankly, it never comes to my mind first. I prefer the messaging approach as it allows me to have independent processes working together. It is just a matter of taste I guess.
