Peeky

Peeky is a Ruby GEM for peaking into ruby classes and extracting meta

When using the source code for this gem, start by running bin/setup to install locally or bundle install

@klueless-io - look at show-source

Add this line to your application's Gemfile:

gem 'peeky'

And then execute:

bundle install

Or install it yourself as:

gem install peeky

As a Ruby Developer, I should be able to Reverse engineer classes and methods, so that I can document and understand them

See all stories

• As a Developer, I should be able to interrogate class instance information, so that I can reverse engineer a ruby class
• As a Developer, I can render a method with minimal parameter calls, So that I know the minimum parameters when calling a method
• As a Developer, I can render a class with instance attributes and methods, So that I can quickly mock out an entire class

See all usage examples

This example assumes you have this simple class

module Sample
  class SimpleClass
    attr_accessor :read_write

    def position_and_optional(aaa, bbb = 1)
    end
  end
end      

Here a list of example renderers for the simple class

Render simple class using class_interface renderer with compact formatting

puts api.render_class(:class_interface, instance: Sample::SimpleClass.new)

class SimpleClass
  attr_accessor :read_write

  def position_and_optional(aaa, bbb = nil);                                      end
end

Render simple class using class_interface_yard renderer to product YARD compatible documentation

puts api.render_class(:class_interface_yard, instance: Sample::SimpleClass.new)

class SimpleClass
  # Read write
  attr_accessor :read_write

  # Position and optional
  #
  # @param aaa [String] aaa (required)
  # @param bbb [String] bbb (optional)
  def position_and_optional(aaa, bbb = nil)
  end
end

Render debug information

puts api.render_class(:class_debug, instance: Sample::SimpleClass.new)

----------------------------------------------------------------------
class name                    : SimpleClass
module name                   : Sample
class full name               : Sample::SimpleClass

-- Attributes --------------------------------------------------------
attr_accessor                 : read_write

-- Public Methods ----------------------------------------------------
position_and_optional::
name                 param format         type
----------------------------------------------------------------------
aaa                  aaa                  param_required
bbb                  bbb = nil            param_optional

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
