38 Test2::Formatter - Namespace for formatters.
42 This is the namespace for formatters. This is an empty package.
44 =head1 CREATING FORMATTERS
46 A formatter is any package or object with a C<write($event, $num)> method.
48 package Test2::Formatter::Foo;
53 my $self_or_class = shift;
54 my ($event, $assert_num) = @_;
58 sub hide_buffered { 1 }
72 The C<write> method is a method, so it either gets a class or instance. The two
73 arguments are the C<$event> object it should record, and the C<$assert_num>
74 which is the number of the current assertion (ok), or the last assertion if
75 this event is not itself an assertion. The assertion number may be any integer 0
76 or greater, and may be undefined in some cases.
78 The C<hide_buffered()> method must return a boolean. This is used to tell
79 buffered subtests whether or not to send it events as they are being buffered.
80 See L<Test2::API/"run_subtest(...)"> for more information.
82 The C<terminate> and C<finalize> methods are optional methods called that you
83 can implement if the format you're generating needs to handle these cases, for
84 example if you are generating XML and need close open tags.
86 The C<terminate> method is called when an event's C<terminate> method returns
87 true, for example when a L<Test2::Event::Plan> has a C<'skip_all'> plan, or
88 when a L<Test2::Event::Bail> event is sent. The C<terminate> method is passed
89 a single argument, the L<Test2::Event> object which triggered the terminate.
91 The C<finalize> method is always the last thing called on the formatter, I<<
92 except when C<terminate> is called for a Bail event >>. It is passed the
95 The C<new_root> method is called when C<Test2::API::Stack> Initializes the root
96 hub for the first time. Most formatters will simply have this call C<<
97 $class->new >>, which is the default behavior. Some formatters however may want
98 to take extra action during construction of the root formatter, this is where
