Go-diff is a Go language port of Neil Fraser's google-diff-match-patch code. His original code is available at:
http://code.google.com/p/google-diff-match-patch/
All the code and its tests has been ported. Now there are still several tests failing due to bugs in the port, but since it is a pretty test-complete library, we have a good measure to tell when will it be in a stable state (100% of tests passing). If you feel like contributing to the library, please pick a failing unit test and make it pass, thanks!
In order to run the tests:
cd diff && go test
go get github.com/sergi/go-diff/diff
