NAME

TAP::Parser::Iterator::Process - Iterator for process-based TAP sources

CONTENTS

VERSION

Version 3.36

SYNOPSIS



  use TAP::Parser::Iterator::Process;
  my %args = (
   command  => [python, setup.py, test],
   merge    => 1,
   setup    => sub { ... },
   teardown => sub { ... },
  );
  my $it   = TAP::Parser::Iterator::Process->new(\%args);
  my $line = $it->next;



DESCRIPTION

This is a simple iterator wrapper for executing external processes, used by TAP::Parser. Unless you’re writing a plugin or subclassing, you probably won’t need to use this module directly.

METHODS

    Class Methods

new

Create an iterator. Expects one argument containing a hashref of the form:



   command  => \@command_to_execute
   merge    => $attempt_merge_stderr_and_stdout?
   setup    => $callback_to_setup_command
   teardown => $callback_to_teardown_command



Tries to uses IPC::Open3 & IO::Select to communicate with the spawned process if they are available. Falls back onto open().

    Instance Methods

next

Iterate through the process output, of course.

next_raw

Iterate raw input without applying any fixes for quirky input syntax.

wait

Get the wait status for this iterator’s process.

exit

Get the exit status for this iterator’s process.

handle_unicode

Upgrade the input stream to handle UTF8.

get_select_handles

Return a list of filehandles that may be used upstream in a select() call to signal that this Iterator is ready. Iterators that are not handle based should return an empty list.

ATTRIBUTION

Originally ripped off from Test::Harness.
