Description:
------------
Would be really nice to be able to pass an existing diff and take benefit from the rendering functionality offered by this package. I use this myself to parse the output from svn diff.

This is the dummy engine I use -- this could probably be solved in a better way. To use this class, ATM you need to explicitly instantiate the class:
<?php
$diff = file_get_contents('Text/Diff.php.patch');
$renderer = new Text_Diff_Renderer_inline();
$engine = new Text_Diff_Engine_string_diff($diff);
echo $renderer->render($engine);
?>

Test script:
---------------
class Text_Diff_Engine_string_diff extends Text_Diff
{
function __construct($diff, $dummy = false)
{
if ($dummy == false)
$this->_edits = $this->diff($diff);
}

function diff($diff, $dummy = null)
{
$diff = explode("\n", $diff);

$edits = array();
foreach ($diff as $line) {
switch ($line[0]) {
case ' ':
$edits[] = &new Text_Diff_Op_copy(array(substr($line, 1)));
break;

case '+':
$edits[] = &new Text_Diff_Op_add(array(substr($line, 1)));
break;

case '-':
$edits[] = &new Text_Diff_Op_delete(array(substr($line, 1)));
break;
}
}

return $edits;
}
}
