PPIx::Regexp::Structure::Regexp - Represent the top-level regular expression
=head1 SYNOPSIS
use PPIx::Regexp::Dumper;
PPIx::Regexp::Dumper->new( 'qr{foo}smx' )
->print();
=head1 INHERITANCE
C<PPIx::Regexp::Structure::Regexp> is a
L<PPIx::Regexp::Structure::Main|PPIx::Regexp::Structure::Main>.
C<PPIx::Regexp::Structure::Regexp> has no descendants.
=head1 DESCRIPTION
This class represents the top-level regular expression. In the example
given in the L</SYNOPSIS>, the C<{foo}> will be represented by this
class.
=head1 METHODS
This class provides the following public methods. Methods not documented
here are private, and unsupported in the sense that the author reserves
the right to change or remove them without notice.
=cut
package PPIx::Regexp::Structure::Regexp;
use strict;
use warnings;
use base qw{ PPIx::Regexp::Structure::Main };
our $VERSION = '0.036';
sub can_be_quantified { return; }
=head2 capture_names
foreach my $name ( $re->capture_names() ) {
print "Capture name '$name'\n";
}
This method returns the capture names found in the regular expression.
=cut
sub capture_names {
my ( $self ) = @_;
my %name;
my $captures = $self->find(
'PPIx::Regexp::Structure::NamedCapture')
or return;
foreach my $grab ( @{ $captures } ) {
$name{$grab->name()}++;
}
return ( sort keys %name );
}
=head2 max_capture_number
print "Highest used capture number ",
$re->max_capture_number(), "\n";
This method returns the highest capture number used by the regular
expression. If there are no captures, the return will be 0.
=cut
sub max_capture_number {
my ( $self ) = @_;
return $self->{max_capture_number};
}
# Called by the lexer once it has done its worst to all the tokens.
# Called as a method with no arguments. The return is the number of
# parse failures discovered when finalizing.
sub __PPIX_LEXER__finalize {
my ( $self ) = @_;
my $rslt = 0;
foreach my $elem ( $self->elements() ) {
$rslt += $elem->__PPIX_LEXER__finalize();
}
# Calculate the maximum capture group, and number all the other
# capture groups along the way.
$self->{max_capture_number} =
$self->__PPIX_LEXER__record_capture_number( 1 ) - 1;
return $rslt;
