Exporting JSON to environment variables

by

Borrowing from this answer which does all of the hard work of turning the JSON into key=value pairs, you could get these into the environment by looping over the jq output and exporting them:

for s in $(echo $values | jq -r "to_entries|map(\"\(.key)=\(.value|tostring)\")|.[]" ); do
    export $s
done

If the variables being loaded contain embedded whitespace, this is also reasonable, if slightly more complex:

while read -rd $'' line
do
    export "$line"
done < <(jq -r <<<"$values" \
         'to_entries|map("\(.key)=\(.value)\u0000")[]')
