#sorted_ya2yaml(options = {}) ⇒ Object

ya2yaml will output hash keys in sorted order, but it outputs arrays in natural order. This new method, sorted_ya2yaml(), is the same as ya2yaml but ensures that arrays are sorted.

This is important so that the .yaml files don't change each time you recompile.
