Kupu
Encyclopedia
Kupu was a 'document-centric' open source
client-side
editor for Mozilla
, Netscape
and Internet Explorer
. Inspired by Maik Jablonski's Epoz editor, it was written by Paul Everitt, Guido Wesdorp and Philipp von Weitershausen (and several other contributors, for a complete list refer to the CREDITS.txt file) to improve the JavaScript
code and architecture, pluggability, standards support, support for other webservers than Zope
(which was the original target platform for Epoz), configurability and a lot of other issues. Nowadays Kupu is the default WYSIWYG
editor for the Plone
CMS
, and is mostly maintained by Duncan Booth. It is made available under a BSD-style
license.
. Currently there is integration code for Zope 2, Plone
and Apache Lenya
.
Kupu can be customized and extended in several ways. For simple modifications much of the configuration can be set as attributes on the editor iframe, while buttons, tools and layout can be changed via the CSS
. For larger customizations there's a JavaScript plugin API, and also the core has a clean and solid architecture to allow full extensibility.
Kupu uses CSS in favor of HTML
for layout and presentation. It supports asynchronous saving to the server and sets event handlers from code instead of from the HTML (excepting the toolbar), which makes the code a lot cleaner. It uses DOM functionality to build up HTML. On those and other fronts it tries to use the most modern standardized techniques available on all supported browsers to ensure a good user-experience and clean code.
