Re: [xwiki-users] [Code snippet] Full user name and link by log-in

[coldserenity]

Transformation into XWiki macro went with ease :)
A lot less code in the pages now.

I did an enhancement on the actual snippet itself, now it's capable of
accepting comma-separated lists of log-ins, transforming them into
comma-separated list of [full-user-name-link-to-user-page].

{{velocity}}
#macro(displayFullNameByLogin $logins)
  ## split incoming string by zero-or-more number of
  ##   ’ ’ (space), ’\t’ (tab) and ’,’ (comma) 
  ## symbols. This way there will be less empty elements in the resulting
array

  #foreach( $login in $userLoginsArray )
      #if ("$!login" == "" )
        ## ignore null or empty (see

      #else
        #set($userDocName = "XWiki."+$login)
        ## check for last iteration before appending ",&nbsp"

        $xwiki.getUserName($userDocName, true)#if( $velocityHasNext
), #end
      #end 
  #end
{{/html}}
#end
{{/velocity}}

Thanks for the hints! :)
