Hi Jukone,

The idiom I have seen used and use myself is...
withing File1.rb

require File.dirname(__FILE__) + '/../../Dir1/File1.rb'

Hope that helps.

Some recommend being a bit more implicit with the path structure. So
more along the lines of,

require File.join(File.dirname(__FILE__), '..', '..', 'Dir1',
'File1'))

File.join will apply the proper file separator for any given platform
running your code. Btw, there is no need to put the '.rb' extension -
it is implied.

I have been meaning to finish my 'relative require' gem, http://elreq.rub...,
that allows you to just do the following,

require '../../Dir1/File1'

Which I find much nicer, cleaner and easier. The gem is finished, I
just need to publish it. I'll do that this weekend.

$:.unshift(File.basename($0))
require "../Dir2/File2.rb"
require "../Dir3/File3.rb"
require "../Dir4/File4.rb"
....

Oops. Those should have been "../../Dir2/File2.rb" &c.

Heh...I'm not batting so well here. That should also have been
File.dirname, not basename! And probably the path should be expanded.
One more try here...

$:.unshift(File.expand_path(File.dirname($0)))
require "../../Dir2/File2.rb"
require "../../Dir3/File3.rb"
require "../../Dir4/File4.rb"
....
