TAP::Parser::Iterator::Process - Iterator for process-based TAP sources
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.
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
Iterate through the process output, of course.
Iterate raw input without applying any fixes for quirky input syntax.
Get the wait status for this iterator's process.
Get the exit status for this iterator's process.
Upgrade the input stream to handle UTF8.
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.
