# NAME

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

# VERSION

Version 3.48

# 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]);
      }
