       Test2::Formatter - Namespace for formatters.


       This is the namespace for formatters. This is an empty package.


       A formatter is any package or object with a "write($event, $num)"

           package Test2::Formatter::Foo;
           use strict;
           use warnings;

           sub write {
               my $self_or_class = shift;
               my ($event, $assert_num) = @_;

           sub hide_buffered { 1 }

           sub terminate { }

           sub finalize { }


       The "write" method is a method, so it either gets a class or instance.
       The two arguments are the $event object it should record, and the
       $assert_num which is the number of the current assertion (ok), or the
       last assertion if this even is not itself an assertion. The assertion
       number may be any integer 0 or greater, and may be undefined in some

       The "hide_buffered()" method must return a boolean. This is used to
       tell buffered subtests whether or not to send it events as they are
       being buffered.  See "run_subtest(...)" in Test2::API for more

       The "terminate" and "finalize" methods are optional methods called that
       you can implement if the format you're generating needs to handle these
       cases, for example if you are generating XML and need close open tags.

       The "terminate" method is called when an event's "terminate" method
       returns true, for example when a Test2::Event::Plan has a 'skip_all'
       plan, or when a Test2::Event::Bail event is sent. The "terminate"
       method is passed a single argument, the Test2::Event object which
       triggered the terminate.

       The "finalize" method is always the last thing called on the formatter,
       except when "terminate" is called for a Bail event. It is passed the
       following arguments:

       o   The number of tests that were planned

       o   The number of tests actually seen

       o   The number of tests which failed

       o   A boolean indicating whether or not the test suite passed

       o   A boolean indicating whether or not this call is for a subtest
