XWiki Preferences

In XWiki Enterprise 2.x the WYSIWYG content editor is configurable using XWiki preferences. Each preference listed below has a matching configuration parameter which it overwrites.

Preference NameTypeConfiguration Parameter


Administration Section

Starting with XWiki Enterprise 3.0 the recommended way to configure the WYSIWYG content editor is through its global administration section.


Configuring the WYSIWYG editor through XWiki preferences is possible only in XWiki Enterprise 2.x.

Edit XWiki.XWikiPreferences page with the object editor and fill the properties specified in the XWiki Preferences quick reference section above. If the XWiki.XWikiPreferences object doesn't have those properties then you'll have to add them to the class. Finally, reload the edited page to see the WYSIWYG editor changes.

Velocity Templates

The WYSIWYG editor is configured by a velocity macro named wysiwyg_storeConfig which can be found in templates/macros.vm. In older versions of XWiki Enterprise (prior to 1.9) the code of the wysiwyg_storeConfig macro is placed in templates/editwysiwygnew.vm. Use the parameters listed in the Configuration Parameters quick reference section to configure the editor. You may have to restart the server in order for the changes to take effect because velocity templates can be cached at application startup.

Custom Skin

You can overwrite the wysiwyg_storeConfig velocity macro from templates/macros.vm in your custom skin. Reload the edited page to see the WYSIWYG editor changes.


Enable toolbar features

This applies only to XWiki Enterprise 2.x. Starting with 3.x you can use the administration section.

Editing features (e.g. make text bold, change text color) are provided by editor plugins (e.g. text, color). Another way to see this is that similar editing features are grouped together in a plugin (e.g. changing the background color and the text color features form the color plugin). In order to enable a feature and make it available on the toolbar for instance you first have to enable the plugin that provides that feature.

Let's see how you can add the Background Color button to the WYSIWYG editor toolbar. In this example we're going to edit macros.vm template but you can do the same using only XWiki preferences.

First, search for the wysiwyg_storeConfig velocity macro in templates/macros.vm. This macro should have a line like this:

#set($ok = $parameters.put('plugins', $xwiki.getXWikiPreference('wysiwyg.plugins', "submit line separator embed text 
valign list indent history format symbol link image table macro import#if($full && $request.sync) sync#end")))

Add the color plugin:

#set($ok = $parameters.put('plugins', $xwiki.getXWikiPreference('wysiwyg.plugins', "submit line separator embed text color 
valign list indent history format symbol link image table macro import#if($full && $request.sync) sync#end")))

The position of the plugin name in the list is not important. What matters is that it appears in the list so the WYSIWYG editor can load it. You can find what plugins are available in Plugins and Features section of this page.

Next you have to add backcolor feature to the toolbar. Change the following line:

#set($ok = $parameters.put('toolbar', $xwiki.getXWikiPreference('wysiwyg.toolbar', 'bold italic underline strikethrough |
subscript superscript | unorderedlist orderedlist | outdent indent | undo redo | format | hr symbol | paste'


#set($ok = $parameters.put('toolbar', $xwiki.getXWikiPreference('wysiwyg.toolbar', 'bold italic underline strikethrough |
subscript superscript | unorderedlist orderedlist | outdent indent | undo redo | format | hr symbol | paste | backcolor'

You can place the Background Color button anywhere on the toolbar. Just make sure you leave a space before and after, unless its the first or the last feature on the toolbar.

That's it. You have to restart your server because macros.vm is cached by default at application startup. Reload the edited page and you should see the Background Color button appear on the toolbar of your WYSIWYG editor.

Add an 'Insert HTML macro' button on the tool bar

Suppose you use the HTML macro very often and thus you'd like to have a quick way to insert it from the tool bar. You don't use the HTML macro that often? No problem, it works with any macro. You just need to follow this steps:

  1. Add macro:html (or macro:yourCoolMacro if you like yourCoolMacro more) to the tool bar configuration. For XWiki Enterprise 2.x you can follow the previous example. For XWiki Enterprise 3.x please use the administration section.
  2. Set a custom icon for the tool bar button by adding:
.macro-html {
  background-image:url("/xwiki/resources/icons/silk/html.gif") !important;

to your skin. Of course you can use a different icon and you can replace html with the identifier of your macro. The easiest way to adds this CSS fragment to the skin is by adding a XWiki.StyleSheetExtension object to a page and set it to be always used on the wiki.
