NAME
       TAP::Parser::Source::Perl - Stream Perl output

VERSION
       Version 3.17

SYNOPSIS
         use TAP::Parser::Source::Perl;
         my $perl = TAP::Parser::Source::Perl->new;
         my $stream = $perl->source( [ $filename, @args ] )->get_stream;

DESCRIPTION
       Takes a filename and hopefully returns a stream from it.  The filename
       should be the name of a Perl program.

       Note that this is a subclass of TAP::Parser::Source.  See that module
       for more methods.

METHODS
   Class Methods
       "new"

        my $perl = TAP::Parser::Source::Perl->new;

       Returns a new "TAP::Parser::Source::Perl" object.

   Instance Methods
       "source"

       Getter/setter the name of the test program and any arguments it
       requires.

         my ($filename, @args) = @{ $perl->source };
         $perl->source( [ $filename, @args ] );

       "croak"s if $filename could not be found.

       "switches"

         my $switches = $perl->switches;
         my @switches = $perl->switches;
         $perl->switches( \@switches );

       Getter/setter for the additional switches to pass to the perl
       executable.  One common switch would be to set an include directory:

         $perl->switches( ['-Ilib'] );

       "get_stream"

         my $stream = $source->get_stream($parser);

       Returns a stream of the output generated by executing "source". Must be
       passed an object that implements a "make_iterator" method. Typically
       this is a TAP::Parser instance.

       "shebang"

       Get the shebang line for a script file.

         my $shebang = TAP::Parser::Source::Perl->shebang( $some_script );

       May be called as a class method

       "get_taint"

       Decode any taint switches from a Perl shebang line.

         # $taint will be 't'
         my $taint = TAP::Parser::Source::Perl->get_taint( '#!/usr/bin/perl -t' );

         # $untaint will be undefined
         my $untaint = TAP::Parser::Source::Perl->get_taint( '#!/usr/bin/perl' );

SUBCLASSING
       Please see "SUBCLASSING" in TAP::Parser for a subclassing overview.

   Example
         package MyPerlSource;

         use strict;
         use vars '@ISA';

         use Carp qw( croak );
         use TAP::Parser::Source::Perl;

         @ISA = qw( TAP::Parser::Source::Perl );

         sub source {
             my ($self, $args) = @_;
             if ($args) {
                 $self->{file} = $args->[0];
                 return $self->SUPER::source($args);
             }
             return $self->SUPER::source;
         }

         # use the version of perl from the shebang line in the test file
         sub _get_perl {
             my $self = shift;
             if (my $shebang = $self->shebang( $self->{file} )) {
                 $shebang =~ /^#!(.*\bperl.*?)(?:(?:\s)|(?:$))/;
                 return $1 if $1;
             }
             return $self->SUPER::_get_perl(@_);
         }
