Subject: Re: saving array

Hmm is narray.rb part of ruby-1.8.x? or a separate package? I'm guessing
that the yaml package implements the #to_yaml method for all the containers
(array, hash etc) which are part of ruby "main". (all thanks to open class
definitions in ruby =D ). So if narray.rb is not part of the stdlib, they
wouldn't have implemented the #to_yaml for you.

Solutions? In your program you can do something like

class NArray
    def to_yaml ()
        ... #Implementation (sorry I'm not familiar with NArray)
    end
end

Archit

P.S. On further scrutiny it revealed that narray.rb is indeed NOT a part
of the stdlib

irb(main):002:0> require 'narray'
LoadError : No such file to load -- narray
        from (irb):2:in `require'
        from (irb):2
irb(main):003:0> require 'narray.rb'
LoadError : No such file to load -- narray.rb
        from (irb):3:in `require'
        from (irb):3
irb(main):004:0> x = NArray.new
NameError : uninitialized constant NArray
        from (irb):4
irb(main):005:0>
