Ruby：CSV到YAML

Question

我有以下csv示例：

en.activerecord.models.admin_user.one;Guide
en.activerecord.models.admin_user.other;Guides
en.simple_captcha.placeholder;Type here

是否有将其转换为Yaml文件的红宝石宝石或方法：

en:
  activerecord:
    models:
      admin_user:
        one: Guide
        other: Guides
  simple_captcha:
    placeholder: Type here

我仍在尝试（使用树数据模型），但没有结果。

任何想法？

Answer 1

require 'yaml'  
hash = {}
file =  "en.activerecord.models.admin_user.one;Guide
en.activerecord.models.admin_user.other;Guides
en.simple_captcha.placeholder;Type here"
file.split("\n").each { |line| hash.deep_merge!(line.split(/\.|;/).reverse.inject() { |m,v| {v => m} }) }

puts YAML.dump(hash)
