Is it possible to specify formatting options for to_yaml in ruby?

Question

The code

require \'yaml\'
puts YAML.load(\"
is_something:
  values: [\'yes\', \'no\']
\").to_yaml

produces

--- 
is_somethin

The latest versions of Ruby use the Psych module for YAML parsing. There aren't many options that you can pass but you can change indention and line width. Check the latest Psych documentation for more details.
