TAP::Parser::Iterator::Process3perl
Iterator for process-based tap sources
Usage
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;
Version
Version 3.52
Overview
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_executemerge => $attempt_merge_stderr_and_stdout?setup => $callback_to_setup_commandteardown => $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.
