NAME
TAP::Parser::Iterator::Process - Iterator for process-based TAP sources
VERSION
Version 3.47
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_commandTries 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.
