HashDeepDiff

Find the exact difference between two Hash objects and build a report to visualize it

Installation

Add this line to your application's Gemfile:

gem 'hash_deep_diff'

And then execute:

$ bundle

Or install it yourself as:

$ gem install hash_deep_diff

Usage

Basic example

left = { a: :a }
right = { a: :b }

HashDeepDiff::Comparison.new(left, right).report

- left[a] = a
+ left[a] = b

please see Documentation for more information

Customization

You can implement and use your own reporting engines with the default HashDeepDiff::Delta objects as a source of the report. In order to do so implement your own version of the reporting engine (example can be found here) and inject it into a Comparison

left = { a: :a }
right = { a: :b }

HashDeepDiff::Comparison.new(left, right, reporting_engine: CustomEngine).report
