# 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.
|
|
|
|
## 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
|
|
|
|
### 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.

### To Install ###
|
|
|
|
This jar is not yet to get at maven central.
|
|
|
|
Just add the code below to your maven dependencies:
|
|
```
|
|
<dependency>
|
|
<groupId>com.github.java-diff-utils</groupId>
|
|
<artifactId>diffutils</artifactId>
|
|
<version>1.2.1</version>
|
|
</dependency>
|
|
```
|
|
|
|
## Coming eventually ##
|
|
|
|
* support for inline diffs in output
|
|
* helpers for showing side-by-side, line-by-line diffs or text with inter-line and intra-line change highlights
|
|
* customization of diff algorithm for better experience while computing diffs between strings (ignoring blank lines or spaces, etc)
|
|
* generating output in other formats (not only unified). E.g. CVS.
