How can I sort YAML files?

Question

I\'ve been trying to sort an i18n translations YAML file with Ruby so I can manage new translations in a better and organized way, but I\'ve been wondering if there is something

Here's another alternative for anyone else who comes across this..

require 'yaml'

yaml = YAML.load(IO.read(File.join(File.dirname(__FILE__), 'example.yml')))

@yml_string = "---\n"

def recursive_hash_to_yml_string(hash, depth=0)
  spacer = ""
  depth.times { spacer += "  "}
  hash.keys.sort.each do |sorted_key|
    @yml_string += spacer + sorted_key + ": "
    if hash[sorted_key].is_a?(Hash)
      @yml_string += "\n"
      recursive_hash_to_yml_string(hash[sorted_key], depth+1)
    else
      @yml_string += "#{hash[sorted_key].to_s}\n"
    end
  end
end

recursive_hash_to_yml_string(yaml)

open(File.join(File.dirname(__FILE__), 'example.yml'), 'w') { |f|
  f.write @yml_string
}
