angular-diff
============

Diff filter for angular.js. Show inline text diff in your page

I took the idea and the algorithm (and the code) from [http://ejohn.org/projects/javascript-diff-algorithm/](http://ejohn.org/projects/javascript-diff-algorithm/)

Install
-------

To use angular-diff you have to:

1. install angular-diff with bower:

    ```bower install angular-diff```

2. In your ```index.html```, include the angular-diff file

    <script src="bower_components/angular-diff/angular-diff.min.js"></script>

In your module declaration you have to include the diff module

    var module = angular.module('yourModule', [
        ...
        'diff',
    ]);

USAGE
-----

It's a filter, you use it in your html like this:

    <div ng-bind-html="oldText|diff:newText"></div>

This will show the diff between ```oldText``` and ```newText```

Note that the filter returns html with ```<ins>``` and ```<del>``` tags, so in order to
display it you have to use ng-bind-html.

Here's a demo, that's worth more than a thousand words:
