HyperEdit
Tumult Whisk is an application for Apple's Mac OS X developed by Jonathan Deutsch.
Development
In 2003, while studying computer science at Indiana's Purdue University, Jonathan Deutsch wrote HyperEdit to create a live HTML editor that would remove the need to save an HTML file and reload it in a browser to test each change. French news site MacGeneration said live preview was a novel idea in 2003. HypedEdit's live preview was built on Apple's newly released open-source WebKit web rendering engine. It was initially released as donationware.HyperEdit was renamed to whisk with the release of version 2.0. Whisk was released as shareware with a free trial, and some of its code was taken from Deutsch's "Hype" web animation application.
Features
The software is primarily targeted at web developers, combining a HTML, PHP and JavaScript editor in one lightweight program. It offers customizable syntax highlighting for these web languages.Its features include W3C validation, a JavaScript debugger, code snippets, and a real-time preview in the application's right pane.
