EXPORTS

$array_ref = filter $events => $PACKAGE

$array_ref = filter $events => $PACKAGE1, $PACKAGE2

$array_ref = filter $events => qr/match/

$array_ref = filter $events => qr/match/, $PACKAGE

This function takes an arrayref of events as the first argument. All additional arguments must either be a package name, or a regex. Any event that is generated by a tool in any of the package, or by a tool that matches any of the regexes, will be returned in an arrayref.

$grouped = group_events($events)

This function iterates all the events in the argument arrayref and splits them into groups. The resulting data structure is:

    { PACKAGE => { SUBNAME => [ $EVENT1, $EVENT2, ... }}
    

If the package of an event is not known it will be put into and arrayref under the '__NA__' key at the root of the structure. If a sub name is not known it will typically go under the '__ANON__' key in under the package name.

In addition there is an '__ALL__' key under each package which stores all of the events sorted into that group.

A more complete example:

    {
        '__NA__' => [ $event->[3] ],
        'Test2::Tools::Basic' => {
            '__ALL__' => [ $events->[0], $events->[1], $events->[2] ],
            plan => [ $events->[0] ],
            pass => [ $events->[1] ],
            ok => [ $events->[2] ],
        },
    }
    

$arrayref = facets TYPE => $events

This function will compile a list of all facets of the specified type that are found in the arrayref of events. If the facet has a "Test2::EventFacet::TYPE" package available then the facet will be constructed into an instance of the class, otherwise it is left as a hashref. Facet Order is preserved.

    my $assert_facets = facets assert => $events;
    # [
    #   bless({ details => 'pass', pass => 1}, 'Test2::EventFacet::Assert'),
    #   bless({ details => 'pass', pass => 1}, 'Test2::EventFacet::Assert'),
    # ]
