Recursive Descent (Glob)

This operator recursively matches (or globs) all children nodes given of a particular element, including that node itself. This is most often used to apply a filter recursively against all matches.

match values form ..

This will, like the jq equivalent, recursively match all value nodes. Use it to find/manipulate particular values.

For instance to set the style of all value nodes in a yaml doc, excluding map keys:

yq '.. style= "flow"' file.yaml

match values and map keys form ...

The also includes map keys in the results set. This is particularly useful in YAML as unlike JSON, map keys can have their own styling and tags and also use anchors and aliases.

For instance to set the style of all nodes in a yaml doc, including the map keys:

yq '... style= "flow"' file.yaml
