# Diffy
[![Build Status](https://travis-ci.org/zotonic/diffy.svg?branch=master)](https://travis-ci.org/zotonic/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
```erlang
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)
