Hello, I’m new to ruby but so far my experience with Ruby has been  
great. I’m unable to open an uri based on the file path.

This works  
require ‘open-uri’  
open(“[http://www.ruby-lang.org/](http://www.ruby-lang.org/)”) {|f|  
f.each\_line {|line| p line}  
}

but this doesn’t

require ‘open-uri’  
open(“file:c://test/test.txt”) {|f|  
f.each\_line {|line| p line}  
}

Can Ruby uri class open up a file schema?

Thanks,  
apparna

Make a test without a drive letter. IOW try a simpler case first. Then,  
if  
this succeeds, try this syntax:

“file:///C:/test/test.txt”

URI paths involving drive letters must be handled very carefully. And  
IMHO,  
drive letters should be banished from the world of computing as soon as  
possible.
