Motivation#

My wiki has a long list of books, some of which end with '?'. This made a real mess when I hadn't filled in the links. And, I had always wanted more control over how missing page links looked anyhow. So, I wrote a filter that recognizes the HTML that JSPWiki generates for missing page links, and replaces them with a pure CSS span, eliminating the '?' along the way. Now, I can fiddle with the CSS all I like, even replacing the '?' if the broswer understands :after. You can see a screen shot of the result on my Column Filter page. This missing page links are in red.

Technical Details#

The key is the filters XML file, where you specify the filter. The filter will then be applied to all pages.

<?xml version="1.0"?>
<pagefilters>
   <filter>
      <class>com.bradfordholcombe.JSPWiki.filters.EditLinkFilter</class>
   </filter>
</pagefilters>

CSS example:

A.needed {
   color: #800;
   text-decoration:none;
   border-bottom: 1px dashed #8f8fff;
}
A.needed:visited {
   color: #800;
   text-decoration:none;
}
A.needed:hover {
   text-decoration:underline;
   color:white;
   background-color: #ff8f8f;
   border-bottom: 1px dashed #ff8f8f;
}

Installation#

Drop the JAR in your lib directory, and update your filter XML and CSS files. That should be it. The source code and JAR are below as attachments.

Bugs#

Please note any bugs or suggestions here. I have tested it extensively on JSPWiki 2.1.103 and Resin 2.1. Let me know if you find any issues.
