Ladies and/or gents, I have found a previous solution that gets really close to what I need, but I guess I am just misunderstanding how it actually works. What I want is to be able to convert a directory structure to a hash or arrays such that it will be easily converted to JSON for presentation to a web application. Here.

UPDATE: I didn't want to delete the original post...so, here is where I am:

Here is the current code, which is not doing what I want it to, and am having trouble wrapping my head around how to get to the structure I want to get. First, the data structure I want:

my @dk = (  {data => [
                    {
                        text => 'data',
                        data => {
                            spriteCssClass => 'folder',
                            'fullPath' => '/data'
                        },
                        contents => [
                                  {
                                    text => 'raw',
                                    data => {
                                        spriteCssClass => 'folder',
                                        fullPath => '/data/raw'
                                    },
                                    contents => [
                                        {
                                            text => 'file1.csv',
                                            data => {
                                                spriteCssClass => 'csv

                                                fullPath => '/data/raw

                                                size => '12345'
                                            }
                                        },
                                        {
                                            text => 'file2.csv',
                                            data => {

Now, the code...which is as far as I have gotten, modifying the previously mentioned code and reference Here.

    my ($directory,$filter) = @_;
    my (@files,@dirs);
    
    find(sub{

        chomp $file;
        my $ref = \@dirs;
        my $truncated = $file;
        $truncated =~ s/^$filter//;
        
        foreach my $dir ( split /\//,$truncated ) {
            my $i = 0;
            next if $dir eq '';
            $i++ while ( $ref->[$i] and $ref->[$i]{name} ne $dir );
