Here is an alternative, using OO technology to obtain the encapsulation (among other things):
use strict;
use warnings;
{
package SomeThing;
my @verbose;
sub new{
my ($class,%params) = @_;
return bless {%params,
}, $class;
}
sub get_info{
my ($self) = @_;
return \@verbose;
}
sub insert{
my ($self,$opt,$info)=@_;
push @verbose, "\n"
. (my $time = ((scalar localtime)=~/(\d\d:\d\d:\d\d)/)[0])
. " \[$info]\n";
return unless $opt->{VERBOSE};
if(length($info) > 55){
$info =~ s/(.{1,50})/$1-]\n\t [-/;
}
print "$time [$info]\n";
}
}
my $obj = new SomeThing(color=>"Blue");
$obj->insert ({VERBOSE=>1}, "This text");
$obj->insert ({VERBOSE=>1}, "That text");
print $_ for @{ $obj->get_info()};
