Hi Erik, So have I understood this right that you're following Eric's model and passing an org table into a shell block whch calls python? I.e. something like #+begin_src sh :var tasks=tasks echo "$tasks" | python gantt.py #+end_src In that case it should be exactly the same as running the python code in a shell outside emacs. To debug this, how about capturing the data that's going into python with #+begin_src sh :var tasks=tasks echo "$tasks" > input-data-for-python #+end_src and then outside emacs doing the equivalent of python gantt.py < input-data-for-python Does that reveal the same problem?
