in reply to Read the Dumper data back to a hash.

I prefer to use the Data::Dump module, since it has a simpler interface and it doesn't try to set any variables, which makes it more convenient to use in most cases. Here is a sample of writing a structure to a file and reading it back again using Data::Dump:

#!perl use strict; use warnings; use Data::Dump qw(dump); # Create a complex structure my %hash = ( number => 42, string => 'This is a string', array => [ 1 .. 10 ], hash => { apple => 'red', banana => 'yellow' }, ); # See what it looks like print "Here is the structure before dumping to file:\n"; dump \%hash; # Print structure to file open my $out, '>', 'dump_struct' or die $!; print {$out} dump \%hash; close $out; # Read structure back in again open my $in, '<', 'dump_struct' or die $!; my $data; { local $/; # slurp mode $data = eval <$in>; } close $in; # See what the structure read in looks like print "Here is the structure after reading from file:\n"; dump $data; __END__
