Use this rule to forbid non-explictly typed truthy values other than ``true``
|
||
|
|
and ``false``, for example ``YES``, ``False`` and ``off``.
|
||
|
|
|
||
|
|
This can be useful to prevent surprises from YAML parsers transforming
|
||
|
|
``[yes, FALSE, Off]`` into ``[true, false, false]`` or
|
||
|
|
``{y: 1, yes: 2, on: 3, true: 4, True: 5}`` into ``{y: 1, true: 5}``.
