Hi all,  
I have 2 files which are placed in two different folders. These folders  
are not under any Classpath & i am using a windows system.

## I have the following snippet of program, which i am stuck with, FILE 1:

class Test

puts " This out is from file1 "

## end

## FILE 2:

require “Test”  
puts “This output is from File2”

## 

If File 1 is and File 2 are in two different locations, i get the  
following error :  
FILE2.rb:1:in `require’: no such file to load – Test (LoadError)  
from run.rb:1  
If both the files are in same folder ,it works but if they are located  
in different locations it fails,  
How can make it work, should i provide anything under “require”

Thanks

First of all, you have to require the name of the file, not the name  
of the class inside, so as you are doing require ‘Test’ I will assume  
that File 1 is called Test.rb.

If the location is always the same relative to File2, I mean, if File2  
can always rely that Test.rb is always  
a sibling directory called xxx, you could do:

require ‘…/xxx/File1’

the $: variable is an array that contains a list of directories that  
require looks for  
files. You can push there that folder if you need to require more than  
one  
file:

$:.unshift “…/xxx”

That variable is initialized, among other things, with whatever you  
pass in the -I  
param to the ruby executable. So you could keep your require ‘Test’ and  
just  
do:

ruby -I …/xxx File2.rb

I hope I don’t have any mistake in the above, it was all from the top  
of my head,  
and not tested, so beware of typos :-).

Hope this helps,

Jesus.
