Feature #2149

Updated by naruse (Yui NARUSE) about 6 years ago

 =begin 
  pre-cleaning the paths of both side of this call and seeing if the RHS exists in the LHS would be a very useful feature for Pathname users; especially those who are trying to evaluate whether or not a path (after cleanup) is a child of another. 
 
  I wrote up a basic implementation, and would be happy to bulletproof it (it doesn't handle relative paths right now, for instance) and write a more formal patch if this is an acceptable addition. 
 
 ```ruby 
 
 
  <pre> 
  class Pathname 
      def include?(other_path) 
          case other_path 
          when String 
             other_path = Pathname.new(other_path)  
          when Pathname 
          else 
              raise "#{other_path.inspect}: Not a Pathname" 
          end 
         
          !!(self.cleanpath.to_s.index(other_path.cleanpath.to_s, 0) == 0) 
      end 
  end 
  </pre> 
 ``` =end
