Add command line option to ignore blank yaml values #15
Description
Activity
Hi, thanks for your suggestion. Actually, it's probably better to output 'null' only on request. I'm using postgres often, and you can actually set how null value should be outputted and it was usefull for me several times.
As a consequence, I would probably change
shyamlto output an empty string for null values, and add a special--display-null-as VALUEoptions. I'm pretty much busy these days so don't expect an implementation of this right now, and I probably need to think it through a little more.Reacted by Matt Bauman
It would be great if there was an output flag to ignore blank yaml values. Currently it outputs
nullMy use case is that I'm using it along with envdir to output a
docker-composefile to an envdir directorythe 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-blankvia a StackOverflow comment http://stackoverflow.com/questions/5014632/how-can-i-parse-a-yaml-file-from-a-linux-shell-script/15113891?noredirect=1#comment48491233_15113891
