=head1 NAME
Test2::Util::Facets2Legacy - Convert facet data to the legacy event API.
=head1 DESCRIPTION
This module exports several subroutines from the older event API (see
L<Test2::Event>). These subroutines can be used as methods on any object that
provides a custom C<facet_data()> method. These subroutines can also be used as
functions that take a facet data hashref as arguments.
=head1 SYNOPSIS
=head2 AS METHODS
package My::Event;
use Test2::Util::Facets2Legacy ':ALL';
sub facet_data { return { ... } }
Then to use it:
my $e = My::Event->new(...);
my $causes_fail = $e->causes_fail;
my $summary = $e->summary;
....
=head2 AS FUNCTIONS
use Test2::Util::Facets2Legacy ':ALL';
my $f = {
assert => { ... },
info => [{...}, ...],
control => {...},
...
};
my $causes_fail = causes_fail($f);
my $summary = summary($f);
=head1 NOTE ON CYCLES
When used as methods, all these subroutines call C<< $e->facet_data() >>. The
default C<facet_data()> method in L<Test2::Event> relies on the legacy methods
this module emulates in order to work. As a result of this it is very easy to
create infinite recursion bugs.
These methods have cycle detection and will throw an exception early if a cycle
is detected. C<uuid()> is currently the only subroutine in this library that
has a fallback behavior when cycles are detected.
=head1 EXPORTS
Nothing is exported by default. You must specify which methods to import, or
use the ':ALL' tag.
=over 4
=item $bool = $e->causes_fail()
=item $bool = causes_fail($f)
Check if the event or facets result in a failing state.
=item $bool = $e->diagnostics()
=item $bool = diagnostics($f)
Check if the event or facets contain any diagnostics information.
=item $bool = $e->global()
=item $bool = global($f)
Check if the event or facets need to be globally processed.
=item $bool = $e->increments_count()
=item $bool = increments_count($f)
Check if the event or facets make an assertion.
=item $bool = $e->no_display()
=item $bool = no_display($f)
Check if the event or facets should be rendered or hidden.
=item ($max, $directive, $reason) = $e->sets_plan()
=item ($max, $directive, $reason) = sets_plan($f)
Check if the event or facets set a plan, and return the plan details.
=item $id = $e->subtest_id()
=item $id = subtest_id($f)
Get the subtest id, if any.
=item $string = $e->summary()
=item $string = summary($f)
Get the summary of the event or facets hash, if any.
=item $undef_or_int = $e->terminate()
=item $undef_or_int = terminate($f)
Check if the event or facets should result in process termination, if so the
exit code is returned (which could be 0). undef is returned if no termination
is requested.
=item $uuid = $e->uuid()
=item $uuid = uuid($f)
Get the UUID of the facets or event.
B<Note:> This will fall back to C<< $e->SUPER::uuid() >> if a cycle is
detected and an event is used as the argument.
