NAME

TAP::Parser::SourceHandler::Executable − Stream output from an executable TAP source

use TAP::Parser::Source;
use TAP::Parser::SourceHandler::Executable;
my $source = TAP::Parser::Source−>new−>raw(['/usr/bin/ruby', 'mytest.rb']);
$source−>assemble_meta;
my $class = 'TAP::Parser::SourceHandler::Executable';
my $vote = $class−>can_handle( $source );
my $iter = $class−>make_iterator( $source );

DESCRIPTION

This is an executable TAP::Parser::SourceHandler − it has 2 jobs:

1. Figure out if the TAP::Parser::Source it’s given is an executable
command ("can_handle").

2. Creates an iterator for executable commands ("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 an executable file. Casts the following votes:

0.9 if it's a hash with an 'exec' key
0.8 if it's a .bat file
0.75 if it's got an execute bit set

"make_iterator"

my $iterator = $class−>make_iterator( $source );

Returns a new TAP::Parser::Iterator::Process for the source. "$source−>raw" must be in one of the following forms:

{ exec => [ @exec ] }
[ @exec ]
$file

"croak"s on error.

"iterator_class"

The class of iterator to use, override if you’re sub-classing. Defaults to TAP::Parser::Iterator::Process.

SUBCLASSING

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

Example

package MyRubySourceHandler;
use strict;
use Carp qw( croak );
use TAP::Parser::SourceHandler::Executable;
use base 'TAP::Parser::SourceHandler::Executable';
# expect $handler−>(['mytest.rb', 'cmdline', 'args']);
sub make_iterator {
my ($self, $source) = @_;
my @test_args = @{ $source−>test_args };
my $rb_file = $test_args[0];
croak("error: Ruby file '$rb_file' not found!") unless (−f $rb_file);
return $self−>SUPER::raw_source(['/usr/bin/ruby', @test_args]);
}
