Diff, Match and Patch Library http://code.google.com/p/google-diff-match-patch/ Neil Fraser This library is currently available in seven different ports, all using the same API. Every version includes a full set of unit tests. C++: * Ported by Mike Slemmer. * Currently requires the Qt library. C#: * Ported by Matthaeus G. Chajdas. Dart: * The Dart language is still growing and evolving, so this port is only as stable as the underlying language. Java: * Included is both the source and a Maven package. JavaScript: * diff_match_patch_uncompressed.js is the human-readable version. Users of node.js should 'require' this uncompressed version since the compressed version is not guaranteed to work outside of a web browser. * diff_match_patch.js has been compressed using Google's internal JavaScript compressor. Non-Google hackers who wish to recompress the source can use: http://dean.edwards.name/packer/ Lua: * Ported by Duncan Cross. * Does not support line-mode speedup. Objective C: * Ported by Jan Weiss. * Includes speed test (this is a separate bundle for other languages). Python: * Two versions, one for Python 2.x, the other for Python 3.x. * Runs 10x faster under PyPy than CPython. Demos: * Separate demos for Diff, Match and Patch in JavaScript.
