Unexpected output when deleting maps about yq HOT 4 CLOSED

yq purposefully keeps the document separator and any comments by default. To get rid of document separators you can use the "--no-doc" flag.

yq 'del(.foo)' --no-doc test.yaml

from yq.

Hmm yeah - you could apply another update if the length of the map is 0. Some thing like:

yq 'del(.foo) | select(length == 0) |= ""' test.yaml
---

So after ".foo" is deleted, if the map length is 0 (has no kids), we can set it to the empty string

from yq.

Is there a different way to perform the delete that wont result in an empty map?
I wouldn't mind (and honestly expected) having just the document separator or an empty string as the output.

from yq.

Thanks!
