Hi,
I have 2 source files...A.rb and B.rb
Methods in A access methods in B and vice versa.
So i put require 'B' in A.rb and require 'A' in B.rb but it gives
NameError.
Please help.

I use ver. 1.8. In that 'require' can access all files in the current
dir.

Hi Marcus,
My main.rb file has some variables that are initialized once and then
they are accessed inside a method.
How should i scope such vars?

require 'Parser'
Parser.parse("Exhibitors.csv", ",")
def self.processRecord(tile_name, category_name, block_name_arr)
........
end
Parser.rb

require 'Processor'
class Parser
def self.parse(dataFile, delimiter)
..........
processRecord(tile, category, [block1, block2, block3, block4])

Nice! Can you show us the Filesystem structure of those 2 files? Are
they in the same directory ?

Yes, they are in the same directory.
I think the problem is Processor.rb has some statements that get
executed when it is 'required' in the other file.
I want just the method to be accessible.
How to do that?

You need to use `require_relative`, instead of `require`. Please try
this.

Thank you for your help, Arup.
I was able to solve my problem using $ vars and if __FILE__ == $0 in the
Processor class.

@Arup
You are completely on the wrong track: in Ruby 1.8 there is
no require_relative! Using require is correct.

Nice to hear! But did you try `require_relative` ?

That sounds so wrong. Global variables usually are considere harmful
or at least really bad style.
You really should try to restructure your code and avoid
circular dependencies if at all possible.

Marcus

But as far as I know, to work `require 'Processor'`, the CWD should be
added to the $LOAD_PATH. Am I right ?
