How can I sort YAML files?

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 to ease the task.

I found a YAML file writer so I can write a hash into a file, but my problem is to sort the hash correctly. If I got hash h, h.sort returns an array and I still haven't figured a simple way to do that.

I have YAML files like this:

pt-br:      global:    misc:      total: "Total"      all: "Todos"      close: "Fechar"      cancel: "Cancelar"    crud:      access: "Acessar"      back: "Voltar"      edit: "Editar"      confirm: "Confirmar"      send: "Enviar"...

(The files are way larger than this)

But I want to sort them this way:

pt-br:      global:    crud:      access: "Acessar"      back: "Voltar"      confirm: "Confirmar"      edit: "Editar"      send: "Enviar"    misc:      all: "Todos"      cancel: "Cancelar"      close: "Fechar"      total: "Total"

I thought that some simple recursive method could help me like this:

def translation_sort(h)  if h.class == Hash    h = h.sort    h.each{|item| translation_sort(item)}  end  hendrequire "yaml"h=YAML.load_file(File.open("~/pt-br.sample.yml"))translation_sort(h)
