\##Introduction##

Engine for performing and rendering text diffs. Basically the old PEAR library but I added 5.3+ namespacing and intend to include a patch method.

\##Installation##

```
composer require martynbiz/diff

```

\##Usage##

```
// code to highlight the difference between strings
$a_lines = explode("\n", $a);
$b_lines = explode("\n", $b);

$check_diff = new \MartynBiz\Diff\Diff( 'auto', array($a_lines, $b_lines) );

// set which render to use
// $renderer = new \MartynBiz\Diff\Renderer\Unified();
$renderer = new \MartynBiz\Diff\Renderer\Inline();

$diff = $renderer->render($check_diff);

```
