=head1 NAME
Lintian::CheckScript - Check script meta data
=head1 SYNOPSIS
use Lintian::CheckScript;
my $cs = Lintian::CheckScript->new ("$ENV{'LINTIAN_ROOT'}/checks/files.desc");
my $name = $cs->name;
foreach my $tag ($cs->tags) {
# $ti is an instance of Lintian::Tag::Info
my $ti = $cs->get_tag ($tag);
print "$tag is a part of the check $name\n";
# Do something with $ti / $tag
}
foreach my $needs ($cs->needs_info) {
print "$name needs $needs\n";
}
if ($cs->is_check_type ('binary') && $cs->is_check_type ('source')) {
# Check applies to binary pkgs AND source pkgs
}
=head1 DESCRIPTION
Instances of this class represents the data in the check ".desc"
files. It allows access to the tags (as Lintian::Tag::Info) and the
common meta data of the check (such as Needs-Info).
=head1 CLASS METHODS
=over 4
=item Lintian::CheckScript->new ($file)
Parses the $file as a check desc file.

sub new {
my ($class, $file) = @_;
my ($header, @tags) = read_dpkg_control ($file);
my $self;
unless ($header->{'check-script'}) {
croak "Missing Check-Script field in $file";
}
$self = {
'name' => $header->{'check-script'},
'type' => $header->{'type'}, # lintian.desc has no type
'abbrev' => $header->{'abbrev'},
'needs_info' => [split /\s*,\s*/, $header->{'needs-info'}//''],
};
$self->{'script_pkg'} = $self->{'name'};
$self->{'script_pkg'} =~ s,/,::,go;

$self->{'type-table'} = {};
for my $t (split /\s*,\s*/o, $self->{'type'}) {

}
}
for my $pg (@tags) {

croak "Missing Tag field for tag in $file" unless $pg->{'tag'};

}
bless $self, $class;
return $self;
}
=item $cs->name
Returns the "name" of the check script. This is the value in the
Check-Script field in the file.
=item $cs->script_pkg
Returns the perl "package" name for the script. Used by the frontend
to run the check.
=item $cs->type
Returns the value stored in the "Type" field of the file. For the
purpose of testing if the check applies to a given package type, the
L</is_check_type> method can be used instead.
Note in rare cases this may return undef. This is the case for the
lintian.desc, where this field is simply not present.
=item $cs->abbrev
Returns the value of the Abbrev field from the desc file.
=cut
Lintian::CheckScript->mk_ro_accessors (qw(name script_pkg type abbrev));
=item needs_info
Returns a list of all items listed in the Needs-Info field. Neither
the list nor its contents should be modified.
=cut
sub needs_info {
my ($self) = @_;
return @{ $self->{'needs_info'} };
}
=item $cs->is_check_type ($type)
Returns a truth value if this check can be applied to a $type package.
Note if $cs->type return undef, this will return a truth value for all
inputs.
=cut
sub is_check_type {
my ($self, $type) = @_;
return 1 if ($self->{'type'}//'ALL') eq 'ALL';
return $self->{'type-table'}->{$type};
}
=item $cs->get_tag ($tagname)
Return the L<tag|Lintian::Info::Tag> or undef (if the tag is not in
this check).
=cut
sub get_tag {
my ($self, $tag) = @_;
return $self->{'tag-table'}->{$tag};
}
=item $cs->tags
Returns the list of tag names in the check. The list nor its contents
should be modified.
=cut
sub tags {
my ($self) = @_;
return keys %{ $self->{'tag-table'}};
