We use InterwikiPlugin to make aliases on CPAN distros on http://search.cpan.org

These aliases are defined on InterWikis page as

I found that if I use such alias with CPAN distro which has name looking like WikiWord then generated HTML for link is wrong.

For example

CPANdist:GraphViz

generates HTML like (line breaks added for clarity)

<a href="http://search.cpan.org/search?mode=dist&amp;query=GraphViz" title="CPAN distributive <span style='background : #FFFFCE;'><font
color="#0000FF>GraphViz</font></span><a href="/twiki/bin/edit/Sandbox/GraphViz?topicparent=Sandbox.TestTopic8">?</a>">CPANdist:GraphViz</a>

what looks like

GraphViz?">CPANdist:GraphViz

After experiments with InterwikiPlugin I found that links are generated correctly if I put $page in single quotes in 'Tooltip Text' field in table on InterWikis page.

Answer

This is the current limitation of the Plugin, you need to watch out to escape $page in the tooltip text. All Interwiki links at TWiki.org are defined that way. See note in InterwikiPlugin:

• Note: The Tooltip Text must not contain any HTML tags (including <nop> escape code), no internal WikiWord links, and no external links. Hint: Escape 'WikiWords' and '$page'.
