SimpleDiff Ruby 1.0

simplediff-ruby is a Ruby gem implementation of the simplediff algorithm. It finds the difference between two arrays of strings, numbers, hashes, or arrays.

require the gem to expose the SimpleDiff class.

require "simplediff-ruby"

Then call SimpleDiff.compare to find the diffs.

source = ['The', 'quick', 'brown', 'fox']
target = ['The', 'slow', 'green', 'turtle']
SimpleDiff.compare(source, target)

The output will be an array of hashes representing the differences between the compared arrays.

[
  { change: '=', content: ['The'] },
  { change: '-', content: ['quick', 'brown', 'fox'] },
  { change: '+', content: ['slow', 'green', 'turtle'] }
]

Use ruby test/test.rb to run the test cases.

$ ruby test/test.rb
