#NAME
TAP::Parser::SourceHandler::Perl - Stream TAP from a Perl executable
#VERSION
Version 3.48
#SYNOPSIS
use TAP::Parser::Source;
use TAP::Parser::SourceHandler::Perl;
my $source = TAP::Parser::Source->new->raw( \'script.pl' );
$source->assemble_meta;
my $class = 'TAP::Parser::SourceHandler::Perl';
my $vote = $class->can_handle( $source );
my $iter = $class->make_iterator( $source );
#DESCRIPTION
This is a Perl TAP::Parser::SourceHandler - it has 2 jobs:
1. Figure out if the TAP::Parser::Source it's given is actually a Perl script ("can_handle").
2. Creates an iterator for Perl sources ("make_iterator").
Unless you're writing a plugin or subclassing TAP::Parser, you probably won't need to use this module directly.
#METHODS
#Class Methods
#can_handle
my $vote = $class->can_handle( $source );
Only votes if $source looks like a file. Casts the following votes:
0.9 if it has a shebang ala "#!...perl"
0.3 if it has any shebang
0.8 if it's a .t file
0.9 if it's a .pl file
0.75 if it's in a 't' directory
0.25 by default (backwards compat)
#make_iterator
my $iterator = $class->make_iterator( $source );
Constructs & returns a new TAP::Parser::Iterator::Process for the source. Assumes $source->raw
contains a reference to the perl script. croak
s if the file could not be found.
The command to run is built as follows:
$perl @switches $perl_script @test_args
The perl command to use is determined by "get_perl". The command generated is guaranteed to preserve:
PERL5LIB
PERL5OPT
Taint Mode, if set in the script's shebang
Note: the command generated will not respect any shebang line defined in your Perl script. This is only a problem if you have compiled a custom version of Perl or if you want to use a specific version of Perl for one test and a different version for another, for example:
#!/path/to/a/custom_perl --some --args
#!/usr/local/perl-5.6/bin/perl -w
Currently you need to write a plugin to get around this.
#get_taint
Decode any taint switches from a Perl shebang line.
# $taint will be 't'
my $taint = TAP::Parser::SourceHandler::Perl->get_taint( '#!/usr/bin/perl -t' );
# $untaint will be undefined
my $untaint = TAP::Parser::SourceHandler::Perl->get_taint( '#!/usr/bin/perl' );
#get_perl
Gets the version of Perl currently running the test suite.
#SUBCLASSING
Please see "SUBCLASSING" in TAP::Parser for a subclassing overview.
#Example
package MyPerlSourceHandler;
use strict;
use TAP::Parser::SourceHandler::Perl;
use base 'TAP::Parser::SourceHandler::Perl';
# 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(@_);
}
