NAME

VERSION

SYNOPSIS

12         # see TAP::Parser::IteratorFactory for preferred usage
13
14         # to use directly:
15         use TAP::Parser::Iterator::Process;
16         my %args = (
17          command  => ['python', 'setup.py', 'test'],
18          merge    => 1,
19          setup    => sub { ... },
20          teardown => sub { ... },
21         );
22         my $it   = TAP::Parser::Iterator::Process->new(\%args);
23         my $line = $it->next;
24

DESCRIPTION

26       This is a simple iterator wrapper for executing external processes,
27       used by TAP::Parser.  Unless you're subclassing, you probably won't
28       need to use this module directly.

METHODS

31   Class Methods
32       "new"
33
34       Create an iterator.  Expects one argument containing a hashref of the
35       form:
36
37          command  => \@command_to_execute
38          merge    => $attempt_merge_stderr_and_stdout?
39          setup    => $callback_to_setup_command
40          teardown => $callback_to_teardown_command
41
42       Tries to uses IPC::Open3 & IO::Select to communicate with the spawned
43       process if they are available.  Falls back onto "open()".
44
45   Instance Methods
46       "next"
47
48       Iterate through the process output, of course.
49
50       "next_raw"
51
52       Iterate raw input without applying any fixes for quirky input syntax.
53
54       "wait"
55
56       Get the wait status for this iterator's process.
57
58       "exit"
59
60       Get the exit status for this iterator's process.
61
62       "handle_unicode"
63
64       Upgrade the input stream to handle UTF8.
65
66       "get_select_handles"
67
68       Return a list of filehandles that may be used upstream in a select()
69       call to signal that this Iterator is ready. Iterators that are not
70       handle based should return an empty list.
