Figure out if the I<raw> source it's given is a file containing raw TAP output. See L<TAP::Parser::IteratorFactory> for more details. 2. Takes raw TAP from the text file given, and converts into an 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 looks like a regular file. Casts the following votes: 0.9 if it's a .tap file 0.9 if it has an extension matching any given in user config. =cut sub can_handle { my ( $class, $src ) = @_; my $meta = $src->meta; my $config = $src->config_for($class); return 0 unless $meta->{is_file}; my $file = $meta->{file}; return 0.9 if $file->{lc_ext} eq '.tap'; if ( my $exts = $config->{extensions} ) { my @exts = ref $exts eq 'ARRAY' ? @$exts : $exts; return 0.9 if grep { lc($_) eq $file->{lc_ext} } @exts; } return 0; } =head3 C<make_iterator> my $iterator = $class->make_iterator( $source ); Returns a new L<TAP::Parser::Iterator::Stream> for the source. C<croak>s on error. =cut sub make_iterator { my ( $class, $source ) = @_; $class->_croak('$source->raw must be a scalar ref') unless $source->meta->{is_scalar}; my $file = ${ $source->raw }; my $fh; open( $fh, '<', $file ) or $class->_croak("error opening TAP source file '$file': $!"); return $class->iterator_class->new($fh); } =head3 C<iterator_class> The class of iterator to use, override if you're sub-classing. Defaults to L<TAP::Parser::Iterator::Stream>. =cut use constant iterator_class => 'TAP::Parser::Iterator::Stream'; 1; __END__ =head1 CONFIGURATION { extensions => [ @case_insensitive_exts_to_match ] } =head1 SUBCLASSING Please see L<TAP::Parser/SUBCLASSING> for a subclassing overview. =head1 SEE ALSO L<TAP::Object>, L<TAP::Parser>, L<TAP::Parser::SourceHandler>, L<TAP::Parser::SourceHandler::Executable>, L<TAP::Parser::SourceHandler::Perl>, L<TAP::Parser::SourceHandler::Handle>, L<TAP::Parser::SourceHandler::RawTAP> =cut
