module ActionView
  # = Action View Debug Helper
  #
  # Provides a set of methods for making it easier to debug Rails objects.
  module Helpers
    module DebugHelper
      # Returns a YAML representation of +object+ wrapped with <pre> and </pre>.
      # If the object cannot be converted to YAML using +to_yaml+, +inspect+ will be called instead.
      # Useful for inspecting an object at the time of rendering.
      #
      # ==== Example
      #
      #   @user = User.new({ :username => 'testing', :password => 'xyz', :age => 42}) %>
      #   debug(@user)
      #   # =>
      #   <pre class='debug_dump'>--- !ruby/object:User
      #   attributes:
      #   &nbsp; updated_at:
      #   &nbsp; username: testing
      #
      #   &nbsp; age: 42
      #   &nbsp; password: xyz
      #   &nbsp; created_at:
      #   attributes_cache: {}
      #
      #   new_record: true
      #   </pre>

          "<pre class='debug_dump'>#{h(object.to_yaml).gsub("  ", "&nbsp; ")}</pre>".html_safe
        rescue Exception  # errors from Marshal or YAML
          # Object couldn't be dumped, perhaps because of singleton methods -- this is the fallback
          "<code class='debug_dump'>#{h(object.inspect)}</code>".html_safe
