psychgus 1.0.0
Easily style YAML files using Psych, like Sequence/Mapping Flow style. Simple example: class CoffeeStyler include Psychgus::Styler def style_sequence(sniffer,node) node.style = Psychgus::SEQUENCE_FLOW end end coffee = { 'Roast'=>['Light', 'Medium', 'Dark', 'Extra Dark'], 'Style'=>['Cappuccino', 'Espresso', 'Latte', 'Mocha']} puts coffee.to_yaml(stylers: CoffeeStyler.new) # Output: # --- # Roast: [Light, Medium, Dark, Extra Dark] # Style: [Cappuccino, Espresso, Latte, Mocha] Class example: class Coffee include Psychgus::Blueberry def initialize @roast = ['Light', 'Medium', 'Dark', 'Extra Dark'] @style = ['Cappuccino', 'Espresso', 'Latte', 'Mocha'] end def psychgus_stylers(sniffer) CoffeeStyler.new end end puts Coffee.new.to_yaml # Output: # --- !ruby/object:Coffee # roast: [Light, Medium, Dark, Extra Dark] # style: [Cappuccino, Espresso, Latte, Mocha] The produced YAML without Psychgus styling (i.e., without CoffeeStyler): # --- # Roast: # - Light # - Medium # - Dark # - Extra Dark # Style: # - Cappuccino # - Espresso # - Latte # - Mocha
