TAP::Parser::Iterator::Process - Iterator for process-based TAP sources
Version 3.42
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 writing a plugin or subclassing, you probably won't need to use this module directly.
newCreate 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_commandTries 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_rawIterate 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_unicodeUpgrade the input stream to handle UTF8.
get_select_handlesReturn 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.
