=head1 NAME
TAP::Parser::SourceHandler::RawTAP - Stream output from raw TAP in a scalar/array ref.
=head1 VERSION
Version 3.42
=cut
our $VERSION = '3.42';
=head1 SYNOPSIS
use TAP::Parser::Source;
use TAP::Parser::SourceHandler::RawTAP;
my $source = TAP::Parser::Source->new->raw( \"1..1\nok 1\n" );
$source->assemble_meta;
my $class = 'TAP::Parser::SourceHandler::RawTAP';
my $vote = $class->can_handle( $source );
my $iter = $class->make_iterator( $source );
=head1 DESCRIPTION
This is a I<raw TAP output> L<TAP::Parser::SourceHandler> - it has 2 jobs:
1. Figure out if the L<TAP::Parser::Source> it's given is raw TAP output
(L</can_handle>).
2. Creates an iterator for raw TAP output (L</make_iterator>).
Unless you're writing a plugin or subclassing L<TAP::Parser>, you probably
won't need to use this module directly.
=head1 METHODS
=head2 Class Methods
=head3 C<can_handle>
my $vote = $class->can_handle( $source );
Only votes if $source is an array, or a scalar with newlines. Casts the
following votes:
0.9 if it's a scalar with '..' in it
0.7 if it's a scalar with 'ok' in it
0.3 if it's just a scalar with newlines
0.5 if it's an array

return 0 if $meta->{file};

return 0.9 if ${ $src->raw } =~ /\d\.\.\d/;
return 0.7 if ${ $src->raw } =~ /ok/;
return 0.3;
}
elsif ( $meta->{is_array} ) {
return 0.5;
}
return 0;
}
=head3 C<make_iterator>
my $iterator = $class->make_iterator( $source );
Returns a new L<TAP::Parser::Iterator::Array> for the source.
C<$source-E<gt>raw> must be an array ref, or a scalar ref.
C<croak>s on error.
