black-magic

Pre-commit hook to sanitize and restore magic commands for code formatters like Black

Handles magic commands induced into .py files by Databricks notebooks, such as:

%load_ext autoreload
%autoreload 2

Firstly blackmagic-sanitize is run to make .py backups, comment out the magic commands, then a formatter hook can be run. Finally, blackmagic-restore unpacks the original .py files from backups.

Sample install:

.pre-commit-hooks.yaml
