HashDiff.diff(a,b) returns array, not object with method should() about hashdiff HOT 4 CLOSED

Yes, should is not part of Hashdiff, it's from the gem RSpec. Normally
there's no need to use "diff.should" except in tests.

Hi there,

I'm a bit confused. I'm following the QuickStart, which says to compare in
the following way (eg.):

diff = HashDiff.diff(a, b)
diff.should == [['-', 'a', 3], ['-', 'b', 2]]

However, variable diff is set to a standard array type and does not have a
method 'should'. Am I missing something? Or did the specs change in the
meantime?

I'm using ruby v 1.9.2. My intention is two compare two complex hash to
see if they're identical. So in the code above, I just want to check if
diff.should == [].

Thanks,

Wim.

Thanks for the quick answer! It confused me a bit, I hope you understand. Perhaps it's possible to adjust the documentation?

So this should be ok, right?

# Test if two hashes have exactly the same content
diff = HashDiff.diff(a, b)
diff.empty?

Will this also work if one of the values happens to be nil?

Perhaps there is a more efficient way of doing this? Eg. a method that returns as soon as a difference is encountered?

Thanks in advance.

Indeed the documentation can be improved a bit to avoid confusion.

Thank you for your response. Using diff.empty? appears to work as expected.

I trust you will make a note for updating the documentation. For the rest, I regard this as a non-issue and hereby close it.

Thank you for your time!
