TAP::Parser::Iterator::Process.3perl

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"

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.
