How to document an inherited constructor using Yard


Having classes, such as:

class Foo
  def initialize(data)
  end
end

class Bar < Foo
end

Each subclass that inherits from Foo has its own unique attributes, passed in via the data options hash.

The yard output for Bar states:

Constructor Details
This class inherits a constructor from Foo

I haven't been able to figure out how to document the options for Bar#initialize.

Attempts include:

class Bar < Foo
  # @overload initialize(data)
  #   @param data [Hash]
  #   @option data [String] :baz Value for baz attribute
end

(does nothing)

class Bar < Foo
  # @param data [Hash]
  # @option data [String] :baz Value for baz attribute
  # @!parse def initialize(data); end
end

(creates an undocumented constructor with "view source" showing the fake method)

class Bar < Foo
  # @!parse
  #   @param data [Hash]
  #   @option data [String] :baz Baz attr
  #   def initialize(data); end
end

(does nothing, result is the same as with @overload above)

How can I document the options for the subclasses using YARD?


Solution

  • Try using this with yard. And ruby version 2.6

    class Foo
      def initialize(data)
      end
    end
    
    class Bar < Foo
      # @overload initialize(data)
      # @param [String] data list
      # def initialize()
      # end
    end
    

    And check the generated class_list.html file.

    Tested it on a Linux distro.


    If there's any other technical issue, or you need a customized Ruby documentation solution as a temporary measure.
