yq Notebook

Useful notes about using yq

1. Display the path to each value in a YAML file

   $ cat << EOF | yq e '.. | select(. == "*") | {(path | join(".")): .} ' -
   > a:
   >   b: foo

> c: bar

def recursiveFormat(args, **kwargs):
    """
    Recursively apply `string.format()` to all strings in a data structure.

    This is intended to be used on a data structure that may contain
    format strings just before it is passed to `json.dump()` or `dumps()`.
    
    Ideally, I'd like to build this into a subclass of `json.JsonEncoder`,
    but it's tricky to separate out string handling in that class.  I'll
    continue to think about it.
