# java-diff-utils
Diff Utils library is an OpenSource library for performing the comparison operations between texts: computing diffs, applying patches, generating unified diffs or parsing them, generating diff output for easy future displaying (like side-by-side view) and so on.

Main reason to build this library was the lack of easy-to-use libraries with all the usual stuff you need while working with diff files. Originally it was inspired by JRCS library and it's nice design of diff module.

**This is originally a fork of java-diff-utils from Google Code Archive.**

## Examples ##

Look [here](https://github.com/wumpz/java-diff-utils/wiki) to find more helpful informations and examples. 

## Main Features ##

  * computing the difference between two texts.
  * capable to hand more than plain ascci. Arrays or List of any type that implements hashCode() and equals() correctly can be subject to differencing using this library
  * patch and unpatch the text with the given patch
  * parsing the unified diff format
  * producing human-readable differences
  * inline difference construction

### Algoritms ###

This library implements Myer's diff algorithm. But it can easily replaced by any other which is better for handing your texts. I have plan to add implementation of some in future.
