Hi,
I have a file with a few settings in, a hash of settings.
EG:
use strict;
use warnings;
our @EXPORT = qw($fileSize);
our $fileSize = { a=> {name => 'small', size => 50}, b=>{name=> 'medium',
size => 75,} c=>{name=> 'large', size => 100} };
These settings are used by several different programs and I don't always
want to apply all the settings. I thought I could do this:
# Make a local copy of HoH
my $ref = $fileSizes;
# remove a hash via key c
delete $ref->{'c'};
Print the original structure
print Dumper($fileSizes);
When I do this I get the reference without the C hash! I'm sure this is by
design, I'm sure there is a good reason for it but how keep a version
private?
Hope
