如何对 YAML 文件进行排序? [英] How can I sort YAML files?

问题描述

我一直在尝试使用 Ruby 对 i18n 翻译 YAML 文件进行排序，以便我可以以更好、更有条理的方式管理新翻译，但我一直想知道是否有什么可以减轻这项任务的.

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.

我找到了一个 YAML 文件编写器，因此我可以将哈希写入文件，但我的问题是正确排序哈希.如果我得到了散列 h，h.sort 会返回一个数组，但我还没有想出一个简单的方法来做到这一点.

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.

我有这样的 YAML 文件:

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"

...

(文件比这个大)

但我想这样对它们进行排序:

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"

我认为一些简单的递归方法可以像这样帮助我:

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
  h
end

require "yaml"
h=YAML.load_file(File.open("~/pt-br.sample.yml"))
translation_sort(h)

推荐答案

其实这是一个很好的问题.您想要对哈希进行深度排序.所以我不喜欢重新发明轮子，然后我搜索了一个好的实现，我找到了一个我喜欢的.看看它 https://gist.github.com/1083930.它工作正常.

Actually this is a nice question. You want to deep sort hashes. So I don't like to re-invent the wheel and then I searched for a good implementation and I found one I like. Take a look at it https://gist.github.com/1083930. It works fine.
