the bash scripts and actually, a python script

 recalculate.sh  setup.sh  watch-and-render.sh  watch_jupytext_sync.sh

•  recalculate.sh
•  setup.sh
•  watch-and-render.sh
•  watch_jupytext_sync.sh

setup.sh

sets up tmux… not sure will use this again but can see the process used
which is essentially

     tmux send-keys -t 2 "nix-shell" Enter
     tmux send-keys -t 2 "ipython" Enter
     tmux send-keys -t 3 "nix-shell" Enter
     tmux send-keys -t 3 "live-server ." Enter
     tmux send-keys -t 4 "nix-shell" Enter
     tmux send-keys -t 4 "python ./watch.py" Enter

watch.py

i suspect this replaces watch-and-render.sh and watch_jupytext_sync.sh

the code
