=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 );

|
|
|
|
=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.

=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

=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.
