Description
It would be great if there was an output flag to ignore blank yaml values. Currently it outputs null
My use case is that I'm using it along with envdir to output a docker-compose file to an envdir directory
the current command:
cat docker-compose.yml | shyaml get-value api.environment | grep -v null | awk -F': ' '{print $2 > ("envdir/" $1)}'
proposed fix would be something like
shyaml get-value api.environment --ignore-blank
