tap::parser::source
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]);
}
