Wysiwyg Editing

Wikiwyg --> is a WYSIWYG browser editor framework --> for wikis. It is designed to be pluggable on top of existing wiki engines -->, with little or no change to the wiki engine’s core software.

Wikiwyg has been successfully integrated with the following wiki engines: Socialtext, Kwiki, MediaWiki, Trac and TWiki.

Wikiwyg is designed to be a modal editor. You can flip back and forth between WYSIWYG and WikiText and Preview modes in a single editing session. Other available/possible modes are Raw-HTML and Multi-User modes. Wikiwyg can even be configured to use just WikiText mode, and still provides many user benefits over a traditional textarea.

Wikiwyg currently support WYSIWYG mode in Firefox and IE 6+. It supports WikiText mode in those browsers, and Safari as well. In unsupported browsers, a Wikiwyg integration should fall back to the wiki engine’s regular edit interface.
