Each element in the diffs array is a “hunk” array, where each element in each “hunk” array is a single change. Each change is a Diff::LCS::ContextChange that contains both the old index and new index values for the change. The “hunk” provides the full context for the changes. Both old and new objects will be presented for changed objects. <code>nil</code> will be substituted for a discarded object.</p> + +<pre class="ruby"><span class="ruby-identifier">seq1</span> = <span class="ruby-node">%w(a b c e h j l m n p)</span> +<span class="ruby-identifier">seq2</span> = <span class="ruby-node">%w(b c d e f j k l m r s t)</span> + +<span class="ruby-identifier">diffs</span> = <span class="ruby-constant">Diff</span><span class="ruby-operator">::</span><span class="ruby-constant">LCS</span>.<span class="ruby-identifier">diff</span>(<span class="ruby-identifier">seq1</span>, <span class="ruby-identifier">seq2</span>, <span class="ruby-constant">Diff</span><span class="ruby-operator">::</span><span class="ruby-constant">LCS</span><span class="ruby-operator">::</span><span class="ruby-constant">ContextDiffCallbacks</span>) + <span class="ruby-comment"># This example shows a simplified array format.</span> + <span class="ruby-comment"># [ [ [ '-', [ 0, 'a' ], [ 0, nil ] ] ], # 1</span> + <span class="ruby-comment"># [ [ '+', [ 3, nil ], [ 2, 'd' ] ] ], # 2</span> + <span class="ruby-comment"># [ [ '-', [ 4, 'h' ], [ 4, nil ] ], # 3</span> + <span class="ruby-comment"># [ '+', [ 5, nil ], [ 4, 'f' ] ] ],</span> + <span class="ruby-comment"># [ [ '+', [ 6, nil ], [ 6, 'k' ] ] ], # 4</span> + <span class="ruby-comment"># [ [ '-', [ 8, 'n' ], [ 9, nil ] ], # 5</span> + <span class="ruby-comment"># [ '+', [ 9, nil ], [ 9, 'r' ] ],</span> + <span class="ruby-comment"># [ '-', [ 9, 'p' ], [ 10, nil ] ],</span> + <span class="ruby-comment"># [ '+', [ 10, nil ], [ 10, 's' ] ],</span> + <span class="ruby-comment"># [ '+', [ 10, nil ], [ 11, 't' ] ] ] ]</span> +</pre> + +<p>The five hunks shown are comprised of individual changes; if there is a related set of changes, they are still shown individually.</p> + +<p>This callback can also be used with <a href="../LCS.html#method-i-sdiff"><code>Diff::LCS#sdiff</code></a>, which will produce results like:</p> + +<pre class="ruby"><span class="ruby-identifier">diffs</span> = <span class="ruby-constant">Diff</span><span class="ruby-operator">::</span><span class="ruby-constant">LCS</span>.<span class="ruby-identifier">sdiff</span>(<span class="ruby-identifier">seq1</span>, <span class="ruby-identifier">seq2</span>, <span class="ruby-constant">Diff</span><span class="ruby-operator">::</span><span class="ruby-constant">LCS</span><span class="ruby-operator">::</span><span class="ruby-constant">ContextCallbacks</span>) + <span class="ruby-comment"># This example shows a simplified array format.</span> + <span class="ruby-comment"># [ [ [ "-", [ 0, "a" ], [ 0, nil ] ] ], # 1</span> + <span class="ruby-comment"># [ [ "+", [ 3, nil ], [ 2, "d" ] ] ], # 2</span> + <span class="ruby-comment"># [ [ "!", [ 4, "h" ], [ 4, "f" ] ] ], # 3</span> + <span class="ruby-comment"># [ [ "+", [ 6, nil ], [ 6, "k" ] ] ], # 4</span> + <span class="ruby-comment"># [ [ "!", [ 8, "n" ], [ 9, "r" ] ], # 5</span> + <span class="ruby-comment"># [ "!", [ 9, "p" ], [ 10, "s" ] ],</span> + <span class="ruby-comment"># [ "+", [ 10, nil ], [ 11, "t" ] ] ] ]</span> +</pre> + +<p>The five hunks are still present, but are significantly shorter in total presentation, because changed items are shown as changes (“!”) instead of potentially “mismatched” pairs of additions and deletions.</p> + +<p>The result of this operation is similar to that of Diff::LCS::SDiffCallbacks.
