NAME

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

CONTENTS

VERSION

Version 3.36

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 its a hash with an exec key
  0.8  if its a .bat file
  0.75 if its 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



croaks 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]);
  }
