Yq

Use yq to parse YAML documents using jq. This gem is a simple wrapper around the executable. It will convert the YAML input into JSON, run jq against it, then convert the output back into YAML. Sometimes, jq will output non-JSON, but yq will just turn that into valid YAML.

jq should be available in your $PATH to use this gem.

$ gem install yq

yq takes input from STDIN:

$ cat stuff.yml | yq '.'
---
stuff:
  foo: 
    bar: baz
   
$ cat stuff.yml | yq '.stuff.foo'
---
bar: baz
    

yq converts the STDIN to JSON, and passes it to jq, along with the jq query you specify. The result is then turned back into YAML.
