=head1 NAME
PPI::Statement::Package - A package statement
=head1 INHERITANCE
PPI::Statement::Package
isa PPI::Statement
isa PPI::Node
isa PPI::Element
=head1 DESCRIPTION
Most L<PPI::Statement> subclasses are assigned based on the value of the
first token or word found in the statement. When PPI encounters a statement
starting with 'package', it converts it to a C<PPI::Statement::Package>
object.
When working with package statements, please remember that packages only
exist within their scope, and proper support for scoping has yet to be
completed in PPI.
However, if the immediate parent of the package statement is the
top level L<PPI::Document> object, then it can be considered to define
everything found until the next top-level "file scoped" package statement.
A file may, however, contain nested temporary package, in which case you
are mostly on your own :)
=head1 METHODS
C<PPI::Statement::Package> has a number of methods in addition to the standard
L<PPI::Statement>, L<PPI::Node> and L<PPI::Element> methods.
=cut
use strict;
use PPI::Statement ();
use vars qw{$VERSION @ISA};
BEGIN {
$VERSION = '1.218';
@ISA = 'PPI::Statement';
}
=pod
=head2 namespace
Most package declarations are simple, and just look something like
package Foo::Bar;
The C<namespace> method returns the name of the declared package, in the
above case 'Foo::Bar'. It returns this exactly as written and does not
attempt to clean up or resolve things like ::Foo to main::Foo.
If the package statement is done any different way, it returns false.
=cut
sub namespace {
my $self = shift;
my $namespace = $self->schild(1) or return '';
$namespace->isa('PPI::Token::Word')
? $namespace->content
: '';
}
=pod
=head2 file_scoped
Regardless of whether it is named or not, the C<file_scoped> method will
test to see if the package declaration is a top level "file scoped"
statement or not, based on its location.
In general, returns true if it is a "file scoped" package declaration with
an immediate parent of the top level Document, or false if not.
Note that if the PPI DOM tree B<does not> have a PPI::Document object at
as the root element, this will return false. Likewise, it will also return
false if the root element is a L<PPI::Document::Fragment>, as a fragment of
a file does not represent a scope.
=cut
sub file_scoped {
my $self = shift;
my ($Parent, $Document) = ($self->parent, $self->top);
$Parent and $Document and $Parent == $Document
and $Document->isa('PPI::Document')
and ! $Document->isa('PPI::Document::Fragment');
}
