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', '', '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.
