NAME¶
TAP::Parser::SourceHandler::Perl - Stream TAP from a Perl executable
VERSION¶
Version 3.28
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" 0.75 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 vars '@ISA'; use TAP::Parser::SourceHandler::Perl; @ISA = qw( 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(@_); }
