Diff Algorithms
Diff Algorithms
This article details the journey of creating a new Go diff library, addressing the shortcomings of existing libraries. It covers the challenges in diff algorithm implementation, including complexity and readability, and explains the design of the new API for arbitrary slices and text. The implementation section delves into preprocessing, heuristics like Anchoring, and post-processing techniques used to improve performance and diff readability, highlighting that different implementations of the same algorithm can yield vastly different results.
Note
i'm glad this was well referenced enough to piece together the many ideas used to make a friendly library (from papers to blogs to live journal)
building from the ground up by selecting the core data structure was impactful to the overall design and achieving the goals that were laid out. helpful to see it in action (and acknowledgement that other data structures may have sufficed)
