ruby -\d 和\p{Digit} 有什么区别?

虽然我在我的正则表达式中使用\p{Alpha}和\p{Space}已经有一段时间了,但我刚刚遇到了\p{Digit},但我找不到任何关于与我通常使用的普通\d相比优缺点的信息。它们之间的主要区别是什么? 最佳答案 \d只匹配ASCII数字,即它等同于类[0-9]。\p{Digit}匹配与\d相同的字符加上任何其他表示数字的Unicode字符。例如匹配阿拉伯数字零(代码点U+0660):"\u0660"#=>"٠""\u0660"=~/\d/#=>nil"\u0660"=~/\p{Digit}/#=>0

ruby - digital ocean 托管 Rails 4 应用程序

这是我第一次部署Rails应用程序,我不知道该怎么做。我在DigitalOcean工作,我有5美元的Droplet,我必须说它们到目前为止很棒,还提供了很好的文档。我一直在读这个,https://www.digitalocean.com/community/articles/how-to-1-click-install-ruby-on-rails-on-ubuntu-12-10-with-digitalocean并且我的服务器上已经有一个应用程序。所以我的问题是,由于我的应用程序在生产模式下在本地运行良好,我可以只在我的Droplet中使用ssh,并用我的应用程序替换现有的应用程序吗?
