TAP::Parser::Iterator::Process - Internal TAP::Parser Iterator
Version 3.17
- # 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;
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.
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().
nextIterate through the process output, of course.
next_raw
Iterate raw input without applying any fixes for quirky input syntax.
waitGet the wait status for this iterator's process.
exitGet 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.
Originally ripped off from Test::Harness.
