jq: nested object, extract top-level id and lift a value from internal object

Question

Given the following xample.json;

[
 {
  \"id\": 12345678,
  \"stuff\": { \"book\": \"shelf\", \"hook\": \"line\", \"took\": \"off\", \"info-spec         


        

Answer 1

I managed to figure it out.

$ jq '.[] | { id, "info-spec": .stuff["info-spec"] }' xample.json
{
  "info-spec": 12,
  "id": 12345678
}
{
  "info-spec": 23,
  "id": 12345679
}

The key here seems to be to use the newkey: .complex["key"] notation for lifting.
