jq-like builtin function support about dasel HOT 4 CLOSED

Hi @magodo, thanks for raising this issue!

Could I ask you to provide an example to make sure I fully understand your request please?

from dasel.

Something like below (imagine a and b contains complex properties inside):

$ cat << EOF | jq 'keys[]'
{
"a": {},
"b": {}
}
EOF
"a"
"b"

from dasel.

This has been implemented in #62 and will be included in the next release v1.9.0.

The syntax is

echo '{"a":{},"b":{}}' | dasel -p json -m '-'
"a"
"b"

Where the usage of - in the property selector tells dasel to return the keys/indexes of the current node.
