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.

Use

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'] }
]

Test

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

$ ruby test/test.rb
