Well to be more precise the script contains functions of course , each of which produces one of the figures and takes the path to the data / data as input. In any case the REPL has no place in such a workflow because I want to be able to check in the script at the end and have a reliable way of reproducing any of the figures I put into the paper later.

You could literally just stick your script into a function and have it be just as reproducible (well, probably more reproducible) and never need to restart julia...
