       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)" method.

           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 { }

           sub supports_tables { return $BOOL }

           sub new_root {
               my $class = shift;


       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 event is not itself an assertion.
       The assertion number may be any integer 0 or greater, and may be undefined in some cases.

       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 information.

       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:

       The "supports_tables" method should be true if the formatter supports directly rendering
       table data from the "info" facets. This is a newer feature and many older formatters may
       not support it. When not supported the formatter falls back to rendering "detail" instead
       of the "table" data.

       The "new_root" method is used when constructing a root formatter. The default is to just
       delegate to the regular "new()" method, most formatters can ignore this.

       ·   The number of tests that were planned

       ·   The number of tests actually seen

       ·   The number of tests which failed

       ·   A boolean indicating whether or not the test suite passed

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

       The "new_root" method is called when "Test2::API::Stack" Initializes the root hub for the
       first time. Most formatters will simply have this call "$class->new", which is the default
       behavior. Some formatters however may want to take extra action during construction of the
       root formatter, this is where they can do that.
