Is it possible to set command line flags for an executable in src blocks? I was thinking of something like this #+BEGIN_SRC python :flags --some_flag=True :tangle test.py import app print(app.FLAGS.some_flag) # -> True #+END_SRC which would be equivalent to running: > python --some_flag=True test.py Thanks, John ----------------------------------- Professor John Kitchin Doherty Hall A207F Department of Chemical Engineering Carnegie Mellon University Pittsburgh, PA 15213 412-268-7803 @johnkitchin http://kitchingroup.cheme.cmu.edu
