Helene: A syntax highlighting text editor in javascript.

Description:

What is Helene

Helene is a syntax highlighting text editor written in javascript. It is meant as a replacement for textarea's in webbased IDE's. Helene is developed by Muze ( http://www.muze.nl/ ) for the Ariadne content management system , but can be used for virtually any other system.

Demo

An online demo of Helene can be found at http://helene.muze.nl/ariadne/loader.php/helene/demo/ . The demo is a cvs/svn head version of Helene and thus may contain more features/bugs than the downloadable release.

Supported browsers

Currently Helene supports Internet Explorer and Mozilla. The javascript code is almost entirely DOM based, so any modern browser should in principle be able to run the code.

Features
