This should be able to handle all cases like
Code:
key=value
key =value
key= value
key = value
     key = value

Now, the sort is the bottleneck Smilie But that's OK

Thanks a lot !

List(3pm)						  LogReport's Lire Documentation						 List(3pm)

NAME

       Lire::Config::List - List Value Object.

DESCRIPTION

       Used for configuration parameters which contains a list of values.

   elements()
       Returns this list's values as an array of Lire::Config::Value object.

   get( $idx )
       Returns the value stored at index $idx of this list. An exception is thrown if the index is out-of-bounds.

   remove( $idx )
       Removes the value stored at index $idx of this list. An exception is thrown if the index is out-of-bounds. It returns the deleted element.

   clear()
       Removes all elements from this list

   append( $val, [ $idx ] )
       Adds $val to after element $idx. If $idx is omitted, the element will be added at the end of the array. A negative index is interpreted
       relative to the end of the array.

   move( $idx, $new_idx )
       Moves element $idx at position $new_idx. Indices can be negative and are interpreted as position relative to the end of the array.
