HeckelDiff

What is HeckelDiff?

HeckelDiff is a Pure Swift implementation of Paul Heckel’s A Technique for Isolating Differences Between Files

Features:

This is a simple diff algorithm that provides the minimum set of steps to transform one collection into another. Transformations are listed as discrete operations:

• Insertion – what items should be inserted into the array, and at what index.
• Deletion – what items should be removed from the array, and at what index.
• Move – what items should be moved, and their origin and destination indices.
• Update – what items should be updated/replaced with new context, and at what index.
