YARD Generator (Atom package)

YARD is a commonly used Ruby documentation tool. This package will accelerate the creation of the YARD-style comments for your methods and classes.

Usage

To use it is as simple as moving the cursor below something that needs documentation and pressing ctrl + enter.

In many cases, this will be the body of a method, but if the cursor is above the topmost method it will search for the next, constant, class, or module.

This will analyse the method (and its params), class, constant, or module and generate the following type of documentation:

# Description of UndocumentedModule 
module UndocumentedModule
  # Description of UndocumentedClass 
  class UndocumentedClass
    MY_CONSTANT = 'Important string'.freeze # Description of MY_CONSTANT 
 
    # Description of #undocumented_method 
    # 
    # @param param1 [Type] describe_param1 
    # @param param2 [Type] default: 3 
    # @param param4 [Type] default: { foo: :bar, baz: 'qux' } 
    # @return [Type] description_of_returned_object 
    def undocumented_method(param1, param2=3, param4 = { foo: :bar, baz: 'qux' })
      'The method is not documented!'
    end
 
    # Description of #method_with_named_params 
    # 
    # @param param1 [Type] describe_param1 
    # @param param2 [Type] default: true 
    # @param param3 [Type] default: nil 
    # @return [Type] description_of_returned_object 
    def method_with_named_params(param1:, param2: true, param3: nil)
      'The method is not documented!'
    end
 
    # Description of .undocumented_method 
    # 
    # @param param1 [Type] describe_param1 
    # @param param2 [Type] default: 3 
    # @return [Type] description_of_returned_object 
    def self.undocumented_class_method(param1, param2=3)
      'The method is not documented!'
    end
  end
end

Tab/shift + Tab keys could be used to jump to the next param, description or Type.

Snippets

Type This then Tab	Produces This
#@E	`#\n# @example example here\n#`
#@O	`# @option parent [Type] argument definition`
#@P	`# @param param_name [Type] describe_param_here`
#@H	`# @param argument [Type]\n# @option parent [Type] argument definition\n# @option parent [Type] argument definition`
#@R	`# @return [Type] definition`

Configuration

Through configuration settings you can add a blank comment line above or below the description, @params, and @return, as well as ensure there is a blank line above the generated comment.

module UndocumentedModule
  class UndocumentedClass
    def undocumented_method(param1, param2=3)
      'The method is not documented!'
    end
  end
end

with minimal spacing changes to (everything set to false):

# Description of UndocumentedModule 
module UndocumentedModule
  # Description of UndocumentedClass 
  class UndocumentedClass
    # Description of #undocumented_method 
    # @param param1 [Type] describe param1 
    # @param param2 [Type] default: 3 
    # @return [Type] description_of_returned_object 
    def undocumented_method(param1, param2=3)
      'The method is not documented!'
    end
  end
end

with maximum spacing changes to(everything set to true):

# 
# Description of UndocumentedModule 
# 
module UndocumentedModule
 
  # 
  # Description of UndocumentedClass 
  # 
  class UndocumentedClass
 
    # 
    # Description of #undocumented_method 
    # 
    # 
    # @param param1 [Type] describe param1 
    # 
    # 
    # @param param2 [Type] default: 3 
    # 
    # 
    # @return [Type] description_of_returned_object 
    # 
    def undocumented_method(param1, param2=3)
      'The method is not documented!'
    end
  end
end

and any combination in between.

Planned Future Development

• Add support for interpreting Hash params with `@options`

# Description of #undocumented_method 
# 
# @param param1 [Type] 
# @option param1 [Type] foo default: nil 
# @option param1 [Type] bar default: nil 
# @option param1 [Type] baz default: nil 
# @return [Type] description_of_returned_object 
def undocumented_method(param1={ foo: nil, bar: nil, baz: nil })
  'The method is not documented!'
end
