=head1 NAME
Lintian::Processable::Installable::Class - Lintian interface to binary package data collection
=head1 SYNOPSIS
my ($name, $type, $dir) = ('foobar', 'binary', '/path/to/lab-entry');
my $collect = Lintian::Processable::Installable::Class->new($name);
=head1 DESCRIPTION

packages.
=head1 INSTANCE METHODS
=over 4
=item is_debug_package
The package probably contains only debug symbols.
=cut
sub is_debug_package {
my ($self) = @_;
return 1
if $self->name =~ /-dbg(?:sym)?/;
return 0;
}
=item is_auto_generated
The package was probably generated automatically.
=cut
sub is_auto_generated {
my ($self) = @_;
return 1
if $self->fields->declares('Auto-Built-Package');
return 0;
}
=item is_transitional
The package is probably transitional, i.e. it probably depends
on stuff will eventually disappear.
=cut
sub is_transitional {
my ($self) = @_;
return 1
if $self->fields->value('Description') =~ /transitional package/i;
return 0;
}
=item is_meta_package
This package is probably some kind of meta or task package. A meta
package is usually empty and just depend on stuff. It also returns
a true value for "tasks" (i.e. tasksel "tasks").
=cut
sub is_meta_package {
my ($self) = @_;
return 1
if $self->fields->value('Description')
=~ /meta[ -]?package|(?:dependency|dummy|empty) package/i;
# section "tasks" or "metapackages" qualifies too
return 1
if $self->fields->value('Section') =~ m{(?:^|/)(?:tasks|metapackages)$};
return 1
if $self->name =~ /^task-/;
return 0;
