Hi,
I have a strange problem with arrays in Perl.
That is to say, for me it is strange and perhaps there is a special reason for it that I do not know of.
Not a real Perl Ace.
This is the program, as an example:

use strict;
my $pu;
my $pu_list_cmd;

Hello,
I'm quite new to perl so my question is rather basic and I know there is probably a simple way around it but I can't seem to find it.

Hello,
I'm looking at simplfying a function that flattens an array, it uses recursion and filters objects by type but this seems to be a waste of resources to me at least, using conditionals like this seems like a bad idea.

tree::simple::visitor::tonestedarray
Tree::Simple::Visitor::ToNestedArray(3pm) User Contributed Perl Documentation Tree::Simple::Visitor::ToNestedArray(3pm)
NAME
Tree::Simple::Visitor::ToNestedArray - A Visitor for creating nested array trees from Tree::Simple objects.
SYNOPSIS
use Tree::Simple::Visitor::ToNestedArray;
my $visitor = Tree::Simple::Visitor::ToNestedArray->new();
# given this Tree::Simple tree
my $tree = Tree::Simple->new("Root")
->addChildren(
Tree::Simple->new("Child1")
->addChildren(
Tree::Simple->new("GrandChild1"),
Tree::Simple->new("GrandChild2")
),
Tree::Simple->new("Child2"),
);
# include the trunk (Root)
$visitor->includeTrunk(1);
# visit the tree
$tree->accept($visitor);
my $array_tree = $visitor->getResults();
# this then creates the equivalent nested array tree:
# [
# 'Root', [
# 'Child1', [
# 'GrandChild1',
# 'GrandChild2'
# ],
# 'Child2'
# ]
# ]
# if you don't include the trunk (Root) then ...
$tree->accept($visitor);
my $array_tree = $visitor->getResults();
# this then creates the following nested array tree:
# [
# 'Child1', [
# 'GrandChild1',
# 'GrandChild2'
# ],
# 'Child2'
# ]
DESCRIPTION
Given a tree constructed from a Tree::Simple heirarchy, this Visitor will create the equivalent tree of nested arrays.
METHODS
new There are no arguments to the constructor the object will be in its default state. You can use the "setNodeFilter" and "includTrunk"
methods to customize its behavior.
includTrunk ($boolean)
Setting the $boolean value to true(1) will cause the node value of the tree's root to be included in the nested array output, setting
it to false will do the opposite.
setNodeFilter ($filter_function)
This method accepts a CODE reference as its $filter_function argument and throws an exception if it is not a code reference. This code
reference is used to filter the tree nodes as they are placed into the array tree. The $filter_function is passed a Tree::Simple
object, and is expected to return the value desired for inclusion into the array tree.
visit ($tree)
This is the method that is used by Tree::Simple's "accept" method. It can also be used on its own, it requires the $tree argument to be
a Tree::Simple object (or derived from a Tree::Simple object), and will throw and exception otherwise.
getResults
This method will return the array tree constructed.
BUGS
None that I am aware of. Of course, if you find a bug, let me know, and I will be sure to fix it.
CODE COVERAGE
See the CODE COVERAGE section in Tree::Simple::VisitorFactory for more inforamtion.
SEE ALSO
These Visitor classes are all subclasses of Tree::Simple::Visitor, which can be found in the Tree::Simple module, you should refer to that
module for more information.
