Ruby中的A / An文章

问题描述

除了a / an文章以外，是否有[ActiveSupport中的#pluralize] [1]之类的东西？

所以基本上我需要类似的东西：

'status'.articleize # => "a status"
'urgent'.articleize # => "an urgent"

解决方法

Linguistics gem似乎可以胜任了。让我们尝试Cary Swoveland的挑战：

require 'linguistics/en'
Linguistics.use(:en)

"one-eyed seaman".en.a
=> "a one-eyed seaman"
"honor".en.a
=> "an honor"

# And OP examples...
"urgent update".en.a
=> "an urgent update"
"status update".en.a
=> "a status update"

,

您可以定义String#articleize以返回适当的English article：

class String
  def articleize
    if self[0] =~ /[aeiou]/i
      "an #{self}"
    else
      "a #{self}"
    end
  end
end

'status'.articleize # => "a status"
'urgent'.articleize # => "an urgent"
