But at some point, one wants to be able to repeat that easily, either to do batch processing, replicate the results (perhaps to tweak a bit more), or be consistent in the processing of other similar data. It would be even better if the GUI could save a script that effectively recreates what was done without requiring any interaction (rather than a lot of hidden machinery to recreate the state).
>> you mean like a .ipynb file? :)  ipython notebooks aren't that far from being a viable platform for building and distributing GUIs.  what's needed, though, are tools for better interactivity using javascript, D3, and the like.  even so, their current incarnation provides a much greater level of interactivity than a normal script while retaining portability and flexibility.

For example, if I want to plot a spectrum and then select features to fit, or mark initial guesses for centers, etc, IPython doesn't do that. I do think that may be within reach in a year or two.

Brian Granger recently posted a lengthy summary of the plans for
IPython post-1.0, which addresses interactivity directly:


>From my discussions with Fernando Perez where we discussed swapping
the yt web GUI to live on top of IPython instead of a homegrown
kernel/server approach, he made it abundantly clear that
reproducibility of GUI/widget/interactive elements in the notebook was
a top design priority.  (Our current approach records all scripting
commands and is mediated by python code, but overall leaves a great
deal to be desired.)  Reproducibility of notebook widgets would be a
good topic for discussion at the reproducibility BOF at SciPy this
year, which Fernando will be a panelist at.
