func YAML ¶

func YAML(sources [][]byte, strict bool) (*bytes.Buffer, error)

YAML deep-merges any number of YAML sources, with later sources taking priority over earlier ones.

Maps are deep-merged. For example,

{"one": 1, "two": 2} + {"one": 42, "three": 3}
== {"one": 42, "two": 2, "three": 3}

Sequences are replaced. For example,

{"foo": [1, 2, 3]} + {"foo": [4, 5, 6]}
== {"foo": [4, 5, 6]}

In non-strict mode, duplicate map keys are allowed within a single source, with later values overwriting previous ones. Attempting to merge mismatched types (e.g., merging a sequence into a map) replaces the old value with the new.

Enabling strict mode returns errors in both of the above cases.
