Python Safe Globals now have more reliable triggering of OnChange call. Added "Onchange" object to accessible runtime variables that let user python code see count of changes and first and last values.
#!/bin/bash
INKSCAPE=inkscape
for i in `cat icons.svg |grep -o -e '%%[^%]*%%'|sed 's/%//g'`
do
if [ $i.png -nt icons.svg ]; then
echo "Skip $i"
else
rm -f $i.png
echo "$INKSCAPE" icons.svg -z -e $i.png -i $i
"$INKSCAPE" icons.svg -z -e $i.png -i $i
fi
done
