YARD Method Overrides A YARD plugin that adds tags for specifying method overrides. The tags added are @extension and @override, which allow you to tag a method as either an extension of a superclass’ definition or a complete override of a superclass’ definition. This makes it easy for the reader to see what’s going on may read up on what may be going on in the superclass.
