Programming

Bored of simple text in your pages? Are you interested in giving life to your wiki? Then you can make use of XWiki's powerful programming API directly from your wiki pages. XWiki offers support for several scripting languages: Velocity, Groovy, Python, Ruby and even PHP.
XWiki exposes an API that allows you to manipulate the wiki and its documents easily.
To whet your appetite simply put the following code in your page:
{{velocity}}
#set($query = "where doc.parent is null or doc.parent='' order by doc.name asc")
#foreach($item in $services.query.xwql($query).execute())
#set($orphanedDoc = $xwiki.getDocument($item))
* [[$orphanedDoc.displayTitle>>$orphanedDoc]] (located in space //$orphanedDoc.space//, contains $orphanedDoc.attachmentList.size() attachments)
#end
{{/velocity}}
#set($query = "where doc.parent is null or doc.parent='' order by doc.name asc")
#foreach($item in $services.query.xwql($query).execute())
#set($orphanedDoc = $xwiki.getDocument($item))
* [[$orphanedDoc.displayTitle>>$orphanedDoc]] (located in space //$orphanedDoc.space//, contains $orphanedDoc.attachmentList.size() attachments)
#end
{{/velocity}}
You'll get a list of orphaned pages (i.e. pages that have no parent). For example:
Check the Developer's Guide and especially the XWiki Scripting section to learn more.
You might also want to check out the Extensions wiki which contains a lot of code snippets that you can reuse in your pages.
