TAP::Parser::Source(3pm) Perl Programmers Reference Guide TAP::Parser::Source(3pm)

NAME

TAP::Parser::Source - Stream output from some source

VERSION

Version 3.17

SYNOPSIS

  use TAP::Parser::Source;
  my $source = TAP::Parser::Source->new;
  my $stream = $source->source(['/usr/bin/ruby', 'mytest.rb'])->get_stream;

DESCRIPTION

Takes a command and hopefully returns a stream from it.

METHODS

Class Methods

"new"

 my $source = TAP::Parser::Source->new;

Returns a new "TAP::Parser::Source" object.

Instance Methods

"source"

 my $source = $source->source;
 $source->source(['./some_prog some_test_file']);
 # or
 $source->source(['/usr/bin/ruby', 't/ruby_test.rb']);

Getter/setter for the source. The source should generally consist of an array reference of strings which, when executed via &IPC::Open3::open3, should return a filehandle which returns successive rows of TAP. "croaks" if it doesn't get an arrayref.

"get_stream"

 my $stream = $source->get_stream;

Returns a TAP::Parser::Iterator stream of the output generated by executing "source". "croak"s if there was no command found.

Must be passed an object that implements a "make_iterator" method. Typically this is a TAP::Parser instance.

"merge"

  my $merge = $source->merge;

Sets or returns the flag that dictates whether STDOUT and STDERR are merged.

SUBCLASSING

Please see "SUBCLASSING" in TAP::Parser for a subclassing overview.

Example

  package MyRubySource;
  use strict;
  use vars '@ISA';
  use Carp qw( croak );
  use TAP::Parser::Source;
  @ISA = qw( TAP::Parser::Source );
  # expect $source->(['mytest.rb', 'cmdline', 'args']);
  sub source {
    my ($self, $args) = @_;
    my ($rb_file) = @$args;
    croak("error: Ruby file '$rb_file' not found!") unless (-f $rb_file);
    return $self->SUPER::source(['/usr/bin/ruby', @$args]);
  }
