draw.io: Export all .drawio files in folder to PDF and PNG while preserving history. Very useful as a post-commit hook.

#!/bin/bash

rm -f *.pdf
rm -f *.png

COMMIT=$(git rev-parse HEAD)

for f in *.drawio
do
	/Applications/draw.io.app/Contents/MacOS/draw.io --export --all-pages --output $f.pdf $f
	/Applications/draw.io.app/Contents/MacOS/draw.io --export --all-pages --output $f.png $f
	
	cp $f.pdf history/$f.${COMMIT::8}.pdf
done
