NAME

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

VERSION

Version 3.20

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 .sh file
   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]);
   }
