=head1 NAME

TAP::Parser::SourceHandler::RawTAP - Stream output from raw TAP in a scalar/array ref.

=head1 VERSION

Version 3.26

=cut

$VERSION = '3.26';

=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

=cut

sub can_handle {
my ( $class, $src ) = @_;
my $meta = $src->meta;

return 0 if $meta->{file};
if ( $meta->{is_scalar} ) {
return 0 unless $meta->{has_newlines};
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.
