How can I get elements out of an array with Template Toolkit?

Question

I have an array of Paths which i want to read out with Template Toolkit. How can I access the array Elements of this array? The Situation is this: ``` my @dirs; opendir(DIR,'./directory/') || die $!; @dirs = readdir(DIR); close DIR; $vars->{'Tree'} = @dirs; ``` Then I call the Template Page like this: ``` $template->process('create.tmpl', $vars) || die "Template process failed: ", $template->error(), "
"; ``` In this template I want to make an Tree of the directories in the array. How can I access them? My idea was to start with a `foreach` in the template like this ``` [% FOREACH dir IN Tree.dirs %] $dir [% END %] ```

Accepted Answer

Use references to pass arrays or hashes into your template:

```
$vars->{'Tree'} = \@dirs;
```

Then in the template:

```
[% FOR d = Tree %]
    [% d %]
[% END %]
```
