Automatic padding of bounding box in Prawn, and allows for filling in the background color. Currently only when specifying height, but I'm open to suggestions.

padded_box_helper.rb

require 'prawn'

module PaddedBoxHelper

  #
  # Fills the background of the box you're in
  #
  def fill_bg_color color
    float do
      fill_color color
      fill_rectangle [0, bounds.height], bounds.width, bounds.height
      reset_font_color
    end
  end

  # 
  # Pads a bounding box by nesting another bounding_box inside it
  # Can also take bg_color as a parameter (you have to specify height for this to work)
  # Syntax:
  # padded_box([x,y], <padding:Integer>, <opts...>, :bg_color => <hex:String>) do
  #   <your block content here>
  # end
  # 
  def padded_box *args, &block
    opt = args.extract_options!
    bg_color = opt.delete(:bg_color)
    padding = args.delete_at(1)
    bounding_box *args, opt do
      fill_bg_color bg_color if bg_color
      bounding_box [padding, bounds.height-padding], width: bounds.width-2*padding, height: bounds.height-2*padding do
        block.call
      end
    end
  end
  
end

Bro, this gist is super clutch. Kudos and thankyou!
