设定base_local(如zh-CN)及目标语言（如en,fr）,针对指定格式的base_local文档，检查键值的变动，确保目标语言（如en,fr）文件及时更新对应的翻译文档。
Add this line to your application's Gemfile:
gem 'i18n-processes', '~> 0.1.2'And then execute:
$ bundle
Or install it yourself as:
$ gem install i18n-processes
-
复制config目录下的文件i18n-processes.yml，添加到你自己的config目录下：
$ cp $(i18n-processes gem-path)/config/i18n-processes.yml config/base_local默认为zh-CN. 设置四个路径：
- source: 原文件存放路径
- translation: 翻译文件存放路径
- translated：翻译后的文件存放路径
- compare：对比文件存放路径，默认为tmp/
-
将需要翻译的中文文件夹放入设置好的目录下，比如source/
-
运行：
i18n-processes preprocessing处理原文件，提取出所有的keys -
运行：
i18n-processes missing先对比上期的原始文件【如果有的话】，存在key相同，value不同的情况则会报错，输出diff：这时可以通过两种方式消除diff：
- 删除翻译文件【比如translation/en/translated】中出现的diff.keys
- 删除上期文件【比如tmp/previous/pre_zh-CN】中出现的diff.keys
在你设置的翻译文件存放路径下，比如translated/，会生成与原文件同结构的文件，内含对应的翻译文件
