func Expand ¶

func Expand(leftMargin int, forceList bool, name string, vals ...string) (string, error)

Expand a dot notated name to a YAML string. The value can be a string or string list. The simplest YAML is: a: b

Nested values are expanded as follows:

a.b.c : v1
  expands to
a:
  b:
    c: v1

If there is more than one value then

a.b : {v1,v2}
  expands to
a:
  b:
    - v1
    - v2

The last segment of the name might be a quoted string, for example:

controller.service.annotations."service\.beta\.kubernetes\.io/oci-load-balancer-shape" : flexible

which translates to

controller:
  service:
    annotations:
      service.beta.kubernetes.io/oci-load-balancer-shape: flexible

If forcelist is true then always use the list format.
