 This gem came about because [rspec](http://github.com/rspec/rspec-expectations) doesn't have a decent differ for matching hashes and/or JSON.

 It has extra functionality in also being able to recursively merge hashes and arrays.
 [sub_diff](http://github.com/shuber/sub_diff) can use regular expressions in its match and subsequent diff
 
 DiffMatcher can match using not only regexes but classes and procs.
 And the difference string that it outputs can be formatted in several ways as needed.

+As for matching JSON, the matchers above work well, but don't allow for matching patterns.
