# TAP::Parser::SourceHandler::Executable(3p)

Stream output from an executable TAP source

## NAME

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

## VERSION

Version 3.50

## 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]);
  }
```
