I had to do something similar to this but my object data was in XML files. In that case I used
XML:Simple but for this application I would use
Config::Tiny as follows.
car.txt contents:
[pinto]
horse_power = 50
price = 10
[corvette]
horse_power = 200
price = 11000
#!/usr/bin/env/perl
use strict;
use warnings;
use Car;
my $car = Car->new('corvette');
print "My ", $car->model, " has ", $car->horse_power, " horsepower!";
1;
package Car;
use strict;
use warnings;
use Config::Tiny;
my $CONFIG = './car.txt';
sub new {
my ($class, $model) = @_;
my $cfg = Config::Tiny->new();
$cfg = Config::Tiny->read($CONFIG);
die warn "No such model $model!\n" unless exists $cfg->{$model};
return bless { model => $model, %{$cfg->{$model}} } , __PACKAGE__
+;
}
sub model {die warn "Can't change model!" if @_ > 1; $_[0]->{model}; }
sub horse_power {$_[0]->{horse_power} = $_[1] if @_ > 1; $_[0]->{horse
+_power}; }
sub price {$_[0]->{price} = $_[1] if @_ > 1; $_[0]->{price}; }
1;
