DokuWiki Cloud Plugin Namespace Discrimination Patch
All this info can be found at the various reference locations. I've added it here for convenience.
None of this work is my own –Jeff 2010-06-07
I made a small modification to this plugin and added the ability to limit the word cloud and tag cloud to specific namespaces. When clicking the word cloud, it will restrict the search to the namespace specified. The tag cloud, however, will still display a full backlinks list. Its only been casually tested, so YMMV. I had to change the syntax up a little bit to allow for namespaces.

Syntax
{{cloud>[ns]#[num]}}
{{tagcloud>[ns]#[num]}}
Where [ns] and [num] are both optional. default ns is *, and default num is still 501). ns shortcuts (.,:,*) are resolved. If using all defaults, simply {{cloud>}} will do.
