  • Hash merging

    This function also works for hashes.
    def $a = hash('a', 'b')
def $b = hash('c', 'd')
def $c = $a|merge($b)


    will make 

    $c['a'] = 'b'
$c['c'] = 'd'


    Very useful for growing hashes iteratively. However, bear in bind that hashes cannot have numbers as keys! I lost an hour trying to figure out why my 
    foreach
    didn't work. :-)

  • How to set a number as key

    There's a simple solution to set a number as key :

    {def $my_hash=hash()}
 
{foreach $items as $index=>$item}
 
{$my_hash=$my_hash|merge(hash(concat('0',$index), $value))}
