# [NAME](#NAME)

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

# [VERSION](#VERSION)

Version 3.52

# [SYNOPSIS](#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](#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](#METHODS)

## [Class 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](#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.
