feature request: diff notebooks

I have a notebook that on a re-run is not producing the same results. I'd like to diff it to the previous checkpoint, but ... I can't. I have not used nbdiff ( https://github.com/tarmstrong/nbdiff ), but that looks interesting.

Hi Paul,

That is odd that a re-run of the same notebook is producing different results! Have you managed to find the cause of the problem? The nbdiff library does look interesting but I'm not sure that it has the functionality you are looking for. It seems to me the purpose of this library is to either merge, or see how different two iPython notebooks are!

Jamie: That's what I want to do, find how different two checkpoints of a notebook are. Let me ask a related question: if a revert to a previous checkpoint, can I then roll forward to the most recent checkpoint, or do I loose all revisions post the reverted checkpoint? I don't see any docs on what happens here.

You can revert freely between checkpoints without losing revisions. Just make sure that if you don't want to lose your current state, that you first save it as a checkpoint. Everything that is in a checkpoint is saved, everything in between is lost.

Jamie: That works. Thanks.
