# TAP::Parser::Iterator::Process - phpMan

## NAME
    [TAP::Parser::Iterator::Process] - Iterator for process-based TAP sources

## VERSION
    Version 3.43

## 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.
