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 ] );

croaks 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(@_); }
