Erlang diff match and patch implementation

Diffy

Diff, Match and Patch implementation for Erlang.

Introduction

Diffy is an erlang implementation of the Diff Match and Patch library for plain text. The implementation uses binaries throughout and is utf-8 aware.

Example

1> diffy:diff(<<"fruit flies like a banana">>, <<"fruit flies eat a banana">>)
[{equal,<<"fruit flies ">>},
 {delete,<<"like">>},
 {insert,<<"eat">>},
 {equal,<<" a banana">>}]

TODO

• cleanup_semantic(diffs()) -> diffs()
• make_patch(Text1, Text2) -> patches(), make_patch(unicode_binary(), diffs()) -> patches(), make_patch(Diffs) -> patches()
• match(Text, Pattern, Loc)
