Diff Match Patch #

This is a port of google-diff-match-patch library to Dart. Initially maintained by localvoid, handed off to jheyne for upgrades.

Algorithms #

This library implements Myer's diff algorithm which is generally considered to be the best general-purpose diff. A layer of pre-diff speedups and post-diff cleanups surround the diff algorithm, improving both performance and output quality.

This library also implements a Bitap matching algorithm at the heart of a flexible matching and patching strategy.

  • Support for Dart 2.0

v0.2.2 (2018-10-09) #

  • Upgrade from unittest to test package

v0.2.1 (2014-10-01) #
