NAME
       TAP::Parser::Iterator::Process - Internal TAP::Parser
       Iterator

VERSION
       Version 3.17

SYNOPSIS
         # see TAP::Parser::IteratorFactory for preferred usage

         # to use directly:
         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
       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"

TAP::Parser::IterPerl:ProgrammeTAP::Parser::Iterator::Process(3p)


       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.
