You seem to be hard-coding information about a specific battery into the battery class.

That would be like if I was trying to create a class to represent people, hard-coding my personal details as the defaults.

use 5.010; { package Acpi::Info; use Moose; my @attrs = qw< name type online status present technology voltage_min_design voltage_now current_now charge_full_design charge_full charge_now model_name manufacturer serial_number >; for my $attr (@attrs) { has $attr => ( is => "ro", lazy => 1, default => sub { my $self = shift; $self->_build($attr) } ); } sub _build { my ($self, $key) = @_; my $data = $self->_data; $key = "POWER_SUPPLY_" . uc($key); $data =~ /^$key=(.+?)$/m and $1; } has file => ( is => "ro", isa => "Str", ); has _data => ( is => "ro", isa => "Str", lazy => 1, builder => '_build_data', ); sub _build_data { my $self = shift; local @ARGV = $self->file; local $/ = <ARGV>; } } # Usage # my $i1 = Acpi::Info->new(file => '/sys/class/power_supply/BAT1/uevent' +); my $i2 = Acpi::Info->new(file => '/sys/class/power_supply/ACAD/uevent' +); for my $supply ($i1, $i2) { say "----"; for my $attr ($supply->meta->get_all_attributes) { my $aname = $attr->name; next if $aname =~ /^_/; say $aname, " = ", $supply->$aname; } }
perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
