Hi,

I'm new both to this mailing list and to Ruby. Here's an example, question
will come later.

>> private.rb

class PrivateMethodTest
    private
    def privateMethod(the_string)
        'haha! ' + the_string
    end

    public
    def publicMethod(the_string)
        self.privateMethod(the_string)
    end
end


>> private_test.rb

require 'private.rb'
require 'test/unit'

class PrivateMethodTestTest < Test::Unit::TestCase

    def test_publicMethod
        var = PrivateMethodTest.new()
        assert_equal('haha! test', var.publicMethod('test'))
    end
end

Now the question: why is it, that when the self. (bolded in the code) is
there, the test fails, whereas if I remove it, the test is successful? This
is the failure message:

  1) Error:
test_publicMethod(PrivateMethodTestTest):
NoMethodError: private method `privateMethod' called for
#<PrivateMethodTest:0x2b0876d805a0>
    ./private.rb:9:in `publicMethod'
    private_test.rb:8:in `test_publicMethod'

What am I missing?

Thanks for any help and sorry if this question is silly :)
Cheers,
Chris
