Velocity Macros

Some Velocity queries

• Admin rights
  #if ($xwiki.hasAdminRights())
    The current user has admin rights
  #end

• Edit rights
  #if($hasEdit)
    The current user has edit rights
  #end

• Language
  #if ($context.language == "de")
    German translation is required
  #elseif ($context.language == "fr")
    French translation is required
  #else
    THE LANGUAGE "$context.language" IS NOT SUPPORTED.
  #end

Create Velocity Macro

1. Add a new macro to the file "macros.vm"
   • see "<xwiki-installation-root>/xwiki/templates"
   • add at the end of the file your new macro, for example:
     #macro(myMacroName)
     Hello World!
     #end
2. Register the new macro in the file "macros.txt"
   • see "<xwiki-installation-root>/xwiki/templates"
   • add at the end of the file the line, for example:
     myMacroName=velocity:myMacroName:
3. After XWiki restart the new velocity macro can be used in a common way: either using the WYSIWYG editor or text mode.
