NAME¶

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

VERSION¶

Version 3.23

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.
