lib/psychgus/styler.rb

Overview

Mix in (include) this module to make a class/module/etc. a styler for YAML.

Although it's unnecessary (because of Duck Typing), it's the recommended practice in case a new method is added in the future, and also so you don't have to define methods that you don't use.

You can either use this as is (see example) or inside of a class (see Blueberry).

Examples:

class MyStyler
  include Psychgus::Styler

  def style_sequence(sniffer,node)
    node.style = Psychgus::SEQUENCE_FLOW if sniffer.level == 3
  end
end

hash = {'Coffee'=>{
          'Roast'=>['Light','Medium','Dark','Extra Dark'],
          'Style'=>['Cappuccino','Espresso','Latte','Mocha']
       }}
puts hash.to_yaml(stylers: MyStyler.new())

# Output:
# ---
# Coffee:
#   Roast: [Light, Medium, Dark, Extra Dark]
#   Style: [Cappuccino, Espresso, Latte, Mocha]
