How do I create an empty array in YAML?
array_with_three_elements:
- 1
- 2
- 3
empty_array:
Is there any way to specify that empty_array: is an array with no elements, such as with []? When I load it into a ruby hash I'd like it to know that it's an array.
Thanks
Try using [], like:
empty_array: []
So in Ruby you have:
x = YAML::load("empty_array: []")
x # => {"empty_array" => []}
