NAME
    Data::ResultsHelper - Perl module to helps sort, paginate and display
    results sets

OVERVIEW
      Data::ResultsHelper was written to help display results that can be thought of as an array of arrays.  I
      call the structure results.  Examples abound, and the more I work with it, the more I see examples.  
      Search results, stock ticker quotes, email message summaries, a directory listing, sql query results, 
      this and so much more!

      Data::ResultsHelper takes the results and changes them into a nicely organized hash ref, which can then be
      outputted using Template::Toolkit or the like.

EXAMPLE
      In the below example, I sub-class the Data::ResultsHelper::HTML.  Data::ResultsHelper is general enough that
      results could be outputted in any number of ways: a csv file, XML, etc.  Please consult the Data::ResultsHelper::HTML
      perldoc for more information.  I simply write a generate_results method which sets $self->{results}.  If 
      $self->{set_cookie} is true, I attempt to cache result sets.  In that case, generate_results would only be 
      called to generate fresh results.
  
      #!/usr/bin/perl -w

      use strict;

      {
        my $self = Helper->new({
          results_dir => '/tmp/stuff',
        });
        print "Content-type: text/html\n\n";
        print $self->results2html;
      }

      package Helper;

      use strict;

      use Data::ResultsHelper::HTML;
      use base qw(Data::ResultsHelper::HTML);

      sub generate_results {
        my $self = shift;
        my $dir = shift || $self->{results_dir};
        my $results = [
          ['File', 'Directory', 'Size', 'Modified time'],
        ];
        require File::Find;
        File::Find::find(sub {
          my $fullpath = $File::Find::name = $File::Find::name;
          my $dir = $File::Find::dir;
          my @stat = stat $fullpath;
          return if($fullpath =~ /^\.\.?$/);
          return if(-d _);
          push @{$results}, [$_, $File::Find::dir, $stat[7], $stat[9]];
        }, $dir);
        $self->{results} = $results;
      }
