This web application allows viewing formatted diff/patch files directly from your Gmail or Google Drive.
A hosted version is available here.
-
Apps is hosted using Google App Engine. It uses python backend, but there is very little going on on the server side.
-
The user's files are never copied to the server. Patches are sent from Google server to the client browser for rendering.
-
A small JS library does diff color formatting on the data, locally on the browser.
See Google Cloud Platform github repos for sample applications and scaffolding for other python frameworks and use cases.
Also see Google Drive SDK - Open Files for details about the Drive SDK, how to write apps for Drive and how to integrate open files.
-
I could not figure out how to fetch Google Drive files when running a local web server. I do not think it is possible, since the Drive API configuration requires a real URI, and cannot route to localhost.
-
To test the JavaScript code that colors the diff files, you can use a skeleton html file like:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Test</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<link rel="stylesheet" href="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.2/themes/smoothness/jquery-ui.css" />
<link rel="stylesheet" type="text/css" href="diff.css" />
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.2/jquery-ui.min.js"></script>
<script src="diff.js"></script>
<script type="text/javascript">
$.ajax({
url: "sample.patch",
beforeSend: function( xhr ) {
xhr.overrideMimeType( "text/plain; charset=x-user-defined" );
}
})
.done(function( data ) {
$("#file").html(toDiff(data));
});
</script>
<style>
</style>
</head>
<body>
<div id="file" class="diff"></div>
</body>
</html>
Please place a sample.patch to test rendering.
