Lightweight ipython/jupyter notebook diffing tool

Project description

A lightweight ipython/jupyter notebook diffing tool.



This tool makes ipython/jupyter notebook diffs more readable.

This tool is meant for text-based diffing from the command-line.


Running ndb shows differences in the following types of data:

  • Python code

  • reStructuredText code

  • Resource files (e.g. PNGs)

This will show you most of what has changed in the In[1]: and Out[1]: lines of the notebook.

The output of ndb is git-diff output and can be piped to other commands like less(1) and tee(1).


  • Python >= 2.6

  • nbconvert

  • pandoc

  • git


Install with pip (or your favorite python package manager):

pip install nbd



nbd -h

Simple usage:

nbd <notebook>

Pipe to less(1):

nbd <notebook> | less

Options (see help for all):

nbd -e python <notebook>
nbd <notebook1> <notebook2> <notebook3>
nbd <notebook> --git-diff-option="--name-only"

Build and install from sources

Source distribution:

python sdist

After building, install with pip:

pip install dist/nbd-$version.tar.gz

Install in a virtual environment to avoid system pip issues.
