blargel / easy_diff Goto Github PK

Hi, I've came across a problem with easy_diff that breaks, but I'm not sure why, because for some nested hashes it works fine, here is the gist that demonstrates the weird behaviour:

https://gist.github.com/anonymous/f2995ef213e4c8f8f54c

With given hashes, the output for removed should be an empty hash, but instead it gives whole hash.
I think it's a bug, unless it's not then i would like to know what exactly is causing this.

Easy_diff 0.0.6
ruby -v:
ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-darwin14]

So, I love this tool. But, I'm trying to diff some rather complicated JSON documents, and everything goes swimmingly until an array contains hashes. My preferred behavior would be to recursively diff each hash in the array. I'm looking at the code, and may attempt this myself, but I'm wondering if you've already tried and hit issues.

Steps to Reproduce :
If original = {
:tags => ['a', 'b', 'c'],
:pos => {:x => '1', :y => '2'},
:some_str => "bla",
:some_int => 1,
:some_bool => false,
:extra_removed => "bye"
}

modified = {
:tags => ['b', 'c', 'd'],
:pos => {:x => '1', :y => '2'},
:some_str => "bla",
:some_int => 2,
:some_bool => true,
:extra_added => "hi"
}

Expected Result :

• Then after doing : "removed, added = original.easy_diff modified", the removed and added hash should not contain the key 'pos', as the corresponding key value is same in both hash.

Actual Result :

• Then after doing : "removed, added = original.easy_diff modified", the removed and added hash contains the key 'pos' with value as {} (i.e. :pos => {}).

Tested in version : 0.0.2

Say I have the following:

a = { :a => 1 }
b = { :a => 2, :b => 5 }
remove, added = a.easy_diff(b) # => [{:a=>1}, {:b=>5, :a=>2}]

I would like to get a diff of only when the keys are added or removed, not if the value of a key changes like so:

a = { :a => 1 }
b = { :a => 2, :b => 5 }
remove, added = a.easy_diff(b, :ignore_values => true) # => [{}, {:b=>5}]

Is that possible?
