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

VERSION
    Version 3.43

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 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]);
      }
