#NAME

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

#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.
