# Catalyst::Engine::HTTP::Restarter::Watcher(3pm)

Catalyst::Engine::HTTP::Restarter::Watcher - Watch for changed application files

```
    my $watcher = Catalyst::Engine::HTTP::Restarter::Watcher->new(
        directory => '/path/to/MyApp',
        regex     => '\.yml$|\.yaml$|\.conf|\.pm$',
        delay     => 1,
    );

    while (1) {
        my @changed_files = $watcher->watch();
    }
```

This class monitors a directory of files for changes made to any file matching a regular expression.  It correctly handles new files added to the application as well as files that are deleted.\
 **new ( directory =\> $path** \[, regex =\> `$regex`, delay =\> `$delay ] )` Creates a new Watcher object.\
 **watch** Returns a list of files that have been added, deleted, or changed since the last time watch was called.
