NAME

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

VERSION

       Version 3.23

SYNOPSIS

	 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 vars '@ISA';

	 use Carp qw( croak );
	 use TAP::Parser::SourceHandler::Executable;

	 @ISA = qw( 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]);
	 }
