jQuery Merge for php-diff

A client side merge tool for JBlonds' PHP DIFF. Example

Version

THIS IS A BETA RELEASE!
I had not the time to test this very much so if you rely on this script blindly you may get some unexpected results.
You may help me write some tests to be able to check things better.

Usage

This tool requires a side-by-side or inline diff from php-diff and the full content of the compared files as a line-by-line array.

I use something like this on the server side. Also have a look at the the php-diff examples.

$left = explode("\n", preg_replace('/\r\n|\r/', "\n", $THECONTENTOFFILE_A));
$right = explode("\n", preg_replace('/\r\n|\r/', "\n", $THECONTENTOFFILE_B));

$options = array(
    //'ignoreWhitespace' => true,
    //'ignoreCase' => true,
);

/* Initialize the diff class */
$Diff = new \Diff($left, $right, $options);

/* Initiate the SideBySide or Inline Html renderer */
$Renderer = new \Diff_Renderer_Html_SideBySide;
// $Renderer = new \Diff_Renderer_Html_Inline;

/* Render the Diff-table. */
echo $Diff->render($Renderer);

/* Pass $a and $b to javascript */
echo '<script type="text/javascript">var left='.json_encode($left).', right='.json_encode($right).';'</script>

And this as initiation on the client side. Have a look at this example.

$('.Differences').phpdiffmerge({
    left: left,
    right: right,
    merged: function(merge, left, right) {
    	/* Do something with the merge */
        $.post(
        	'ajax.php',
        	{
        		action: 'merge_completed',
        		merge: merge
        	},
        	function() {
        		console.log('done');
        	}
        );
    }
    /* Use your own "Merge now" button */
    // ,button: '#myButtonId'
    /* uncomment to see the complete merge in a pop-up window */
    // ,pupupResult: true
    /* uncomment to pass additional infos to the console. */
    // ,debug: true
});

Playground

In the project folder:

• Run npm install
• Open a php server php -S localhost:8080
• And open the example page in a browser localhost:8080/example

In the example folder you can find a.txt and b.txt where you can change the compared files.
Inside the index.php you can change the DIFF Style from side-by-side to inline and play with the plugin-options.

Options

Can be set by passing an object into the initiation $('.Differences').phpdiffmerge({option: 'foo'});.
Or by passing an options object to an instance of PHPDiffMerge $('.Differences').phpdiffmerge('option', {option: 'bar'});.

left | string: ""
The full content of the left file as an JavaScript line-by-line array.

right | string: ""
The full content of the right file as an JavaScript line-by-line array.

merged | function: function(result, left, right) {}
A callback function that is called after the merge has completed.
all parameters (same as the left and right inputs) are line-by-line arrays remember to .join('/n') them if you want to use them as strings.

button | mixed {optional}
A Selector or element that will be used as trigger for the final merge. If not set or invalid a button will be generated.

debug | boolean: false
Set true to log the steps made while merging into the console.

pupupResult | boolean: false
If true a pop-up window with the new merged content will be presented after merge.

pupupSources | boolean: false
If true two pup-up windows with the full left and right content will be presented after merge.

Methods

Called as string option on an instance: $('.Differences').phpdiffmerge('method', <arguments>);

useLeft
