YAML string range problem

ruby-talk
1

Hi,

YAML dump/load does roundtrip for range of strings, for example:

require ‘yaml’

t = “0”…"1"
s = YAML.dump(t)
puts YAML.load(s)

gives 0…1 (range of integers). Problem might reside in
yaml/rubytypes.rb or Range#to_s, but I couldn’t fix it well.

_why, have you tried yaml test case in the ruby CVS?

And attached is another test case I haven’t added because…
Locate the file as test/yaml/test_marshal.rb in the src dir.

require ‘test/unit’
require ‘yaml’
require File.join(File.dirname(File.expand_path(FILE)), ‘…/ruby/marshaltestlib’)

module YAML
module Marshal
class TestMarshal < Test::Unit::TestCase
include MarshalTestLib

def encode(o)
o.to_yaml
end

def decode(s)
YAML.load(s)
end
end
end
end

Ok. I’m off on vacation for another three days, checking e-mail on my
handheld. I’ll get this all on Monday. I know exactly the problem. It
is in lib/yaml/rubytypes.rb.

$ cvs ann test_yaml.rb
…
1.10 (akira 08-Feb-04): #

1.12 (nahi 16-Feb-04): t = 0…1
1.12 (nahi 16-Feb-04): assert_equal( t, YAML.load( YAML.dump( t ) ) )
1.10 (akira 08-Feb-04): t = “0”…“1”
1.11 (akira 08-Feb-04): assert_equal( t, YAML.load( YAML.dump( t ) ) )
1.11 (akira 08-Feb-04): t = “…”…“…”
1.11 (akira 08-Feb-04): assert_equal( t, YAML.load( YAML.dump( t ) ) )
1.11 (akira 08-Feb-04): t = “.rb”…“.pl”
1.11 (akira 08-Feb-04): assert_equal( t, YAML.load( YAML.dump( t ) ) )
1.11 (akira 08-Feb-04): t = “.rb”…“.pl”
1.10 (akira 08-Feb-04): assert_equal( t, YAML.load( YAML.dump( t ) ) )
…

So I thought that you didn’t run it or you might failed cvs
update…
