Yard doc and `define_method`

Question

Is there a way to comment methods defined with define_method in YardDoc?

I tried this:

%w(one two three).each do |type|
  # The #{type} way
  # @return [String] the #{type} way
  define_method("#{type}_way") do ... end
end

But, unfortunately, not working.

Answer 1

If you move the method creation into a class method, you could use a macro:

class Foo

  # @!macro [attach] generate
  #   @method $1_way
  #   The $1 way
  #   @return [String] the $1 way
  def self.generate(type)
    define_method("#{type}_way") do
    end
  end

  generate :one
  generate :two
  generate :three

end

YARD Output:

- (String) one_way

The one way

Returns:

(String) — the one way

---

- (String) three_way

The three way

Returns:

(String) — the three way

---

- (String) two_way

The two way

Returns:

(String) — the two way
