Hello,

First off, I am really embarressed to be posting something that I thought would be so easy. I'm trying to parse filenames into hash trees. I'm humbled that I can't make this work. Arg.

#!/usr/bin/perl -w

use strict;
use Data::Dumper;
$Data::Dumper::Deepcopy=1;
$Data::Dumper::Purity=1;
$Data::Dumper::Sortkeys=1;

my @filenames = <DATA>;
chomp @filenames;

my $files = ();

foreach my $file (@filenames) {
   print "processing file: $file\n";
   foreach my $part (reverse split(/[-_.]/,$file)) {
      print "processing part: $part\n";
      # $files = \{$part};            # nope
      # $files = \$files->{$part};    # nope
      # $files = \${$files->{$part}}; # nope
      # $files = \%{$files->{$part}}; # nope
      # $files = $files->{$part};     # nope
      # $files = {$files->{$part}};   # nope
      # $files = {$files->{$part}};   # nope
      # $files = ($files->{$part});   # nope
      # $files = \($files->{$part});  # nope
      # $files = ${$files->{$part}};  # nope
      # $files = {$part => $files};   # nope
      $files->{$part} = \$files;
   }
}

print "\n\nit looks like this:\n";
print Dumper($files);

print "\n\nBut I want it to end up like this:\n";
my $test;
$test->{'0001'}{test}{thing}{sgi} = 1;
$test->{'1'}{tif} = 1;
$test->{'2'}{tif} = 1;
$test->{'10'}{tif} = 1;
$test->{final}{'0001'}{tif} = 1;
$test->{final}{'0002'}{tif} = 1;
$test->{final}{'0003'}{tif} = 1;
$test->{final}{'0004'}{tif} = 1;
# etc....
print Dumper($test);

__DATA__

10.tif
