TAP::Parser::SourceHandler::Executable
NAME
TAP::Parser::SourceHandler::Executable - Stream output from an executable TAP source
VERSION
Version 3.35
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]);
- }
