Calling different class files using require

Ruby
1

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.
