Hi,

I am wondering if there is a nice way to sort a list of strings. I want to transform $my_list = ["c", "d", "a", "b"] => ["a", "b", "c", "d"].

I have looked into the Sort Tool, but that seems to only deal with nodes. Is there a nice way to simply do this?

Thanks!

   Hi,

   If you are willing to turn the list into a map, it is possible:
   

   #set( $items= [] )
   #set( $tmp = $items.add( { "value" : "c" } ) )
   #set( $tmp = $items.add( { "value" : "d" } ) )
   #set( $tmp = $items.add( { "value" : "a" } ) )
   #set( $tmp = $items.add( { "value" : "b" } ) )
   
   
   <ul>
   #foreach ( $item in $_SortTool.sort( $items, [ "value:asc" ] ) )
      <li>$item.value</li>
   #end
   </ul>

   Another way to sort strings is by converting the ArrayList to an Array--then passing that as a sort parameter, for example:

   #set($myList = ["c","d","a","b"])
   #set($sorted = $_SortTool.sort($myList.toArray()))
   
   #foreach($obj in $sorted )
        $obj
   #end

   Thanks for the suggestions Wing and Nadira!!

   I will be using both of these in the future.
