Integration

The decorators plug into the DependencyFactory of Doctrine Migrations. Inside a definition, asking the factory for the service being defined gives the one Doctrine Migrations makes, which the decorator wraps:

$announcements = new Announcements();
$announcer = new Announcer([new Channel('discord_releases', 'en')], new ChatterPublisher($chatter), $logger);

$dependencyFactory->setDefinition(
    MigrationFactory::class,
    static fn (DependencyFactory $factory): MigrationFactory => new AnnouncingMigrationFactory($factory->getMigrationFactory(), $announcements),
);
$dependencyFactory->setDefinition(
    Migrator::class,
    static fn (DependencyFactory $factory): Migrator => new AnnouncingMigrator($factory->getMigrator(), $announcements, $announcer),
);

An application that already gives its own MigrationFactory wraps that one instead of asking the dependency factory for it.

Both decorators share the same Announcements. The library listens to no event of Doctrine Migrations: without the ORM, Doctrine Migrations dispatches them to an event manager no one can reach, while the migrator sees every run whatever the application.

A Publisher of the application's own replaces ChatterPublisher to send anywhere else.
