Development Capabilities

Scripting in Pages (1/2)

{{groovy}}
@Grab(group="org.codehaus.groovy.modules.http-builder",
  module="http-builder", version="0.5.1")
import groovyx.net.http.*

def http = new HTTPBuilder( "http://nexus.xwiki.org/nexus/" )
def resp = http.get( path: "service/local/repositories")

println "|=Name|=Type|=Location"
resp.data."repositories-item".each() {
  println "|${it.name}|${it.repoType}|${it. contentResourceURI}"
}
{{/groovy}}

#set ($xwql = "where doc.content like '%welcome%'")
#foreach ($item in $services.query.xwql($xwql).execute())
 #if ($request.confirm == "1")
   #set ($itemDoc = $xwiki.getDocument($item))
    $itemDoc.setContent($itemDoc.getContent().replaceAll(
     "welcome", "bienvenue"))
    $itemDoc.save("Replaced bienvenue")
    * [[$item>>$item]] replaced!
 #else
    * [[$item>>$item]]
