nbcheck

Simple CLI tool to check Jupyter notebook reproducibility, highlighting cells executed out of order.

Usage as pre-commit hook

This repo is written as a plugin to the pre-commit framework. Commits will only pass if all notebook cells are executed in order. To ignore the warning, users will need to pass the --no-verify flag to git commit.

If you're following the pre-commit quickstart, this is part of Step 2. Specify this repo as part of .pre-commit-config.yaml as follows:

repos:
-  repo: https://github.com/tnwei/nbcheck
   rev: v0.0.2
   hooks:
     - id: nbcheck

Note: replace rev with the latest tag on this repo.
