package TAP::Parser::Iterator::Stream; use strict; use warnings; use base 'TAP::Parser::Iterator'; =head1 NAME TAP::Parser::Iterator::Stream - Iterator for filehandle-based TAP sources =head1 VERSION Version 3.42 =cut our $VERSION = '3.42'; =head1 SYNOPSIS use TAP::Parser::Iterator::Stream; open( TEST, 'test.tap' ); my $it = TAP::Parser::Iterator::Stream->new(\*TEST); my $line = $it->next; =head1 DESCRIPTION This is a simple iterator wrapper for reading from filehandles, used by L<TAP::Parser>. Unless you're writing a plugin or subclassing, you probably won't need to use this module directly. =head1 METHODS =head2 Class Methods =head3 C<new> Create an iterator. Expects one argument containing a filehandle. =cut # new() implementation supplied by TAP::Object sub _initialize { my ( $self, $thing ) = @_; $self->{fh} = $thing; return $self; } =head2 Instance Methods =head3 C<next> Iterate through it, of course. =head3 C<next_raw> Iterate raw input without applying any fixes for quirky input syntax. =head3 C<wait> Get the wait status for this iterator. Always returns zero. =head3 C<exit> Get the exit status for this iterator. Always returns zero. =cut sub wait { shift->exit } sub exit { shift->{fh} ? () : 0 } sub next_raw { my $self = shift; my $fh = $self->{fh}; if ( defined( my $line = <$fh> ) ) { chomp $line; return $line; } else { $self->_finish; return; } } sub _finish { my $self = shift; close delete $self->{fh}; } sub get_select_handles { my $self = shift; # return our handle in case it's a socket or pipe (select()-able) return ( $self->{fh}, ) if (-S $self->{fh} || -p $self->{fh}); return; } 1; =head1 ATTRIBUTION Originally ripped off from L<Test::Harness>. =head1 SEE ALSO L<TAP::Object>, L<TAP::Parser>, L<TAP::Parser::Iterator>, =cut
