Output cells make it difficult to manage iPython notebooks under Git. Diffs become noisy and merge conflicts become common.

This has been adapted from cfriedline's ipynb_template and minrk's original gist with the goal of making output stripping as easy as possible.

First you need to install the ipynb_stripout script. Run the following from your terminal:

wget -O /usr/local/bin/ipynb_stripout "https://raw.githubusercontent.com/jond3k/ipynb_stripout/master/ipynb_stripout"
chmod +x /usr/local/bin/ipynb_stripout

To make it optionally available to all your git repositories:

git config --global filter.ipynb_stripout.clean ipynb_stripout
git config --global filter.ipynb_stripout.smudge cat
git config --global filter.ipynb_stripout.required

Go to the root of the repository you want to add it to and .gitattributes with the following line:

echo "*.ipynb filter=ipynb_stripout" >> .gitattributes

Now you can commit the attributes.

git add .gitattributes
git commit -m "Added ipynb_stripout. See https://github.com/jond3k/ipynb_stripout" .gitattributes
