Use this rule to forbid any string values that are not quoted.
|
|
You can also enforce the type of the quote used using the ``quote-type`` option
|
|
(``single``, ``double`` or ``any``).
|
|
|
|
**Note**: Multi-line strings (with ``|`` or ``>``) will not be checked.

foo: "bar"

bar: 'foo'

number: 123
|

boolean: true
