NAME

File::ChangeNotify::Event - Class for file change events

VERSION

version 0.31

SYNOPSIS

    my $watcher = File::ChangeNotify->instantiate_watcher(
        directories => [ '/my/path', '/my/other' ],
        filter      => qr/\.(?:pm|conf|yml)$/,
        exclude => [ 't', 'root', qr(/(?!\.)[^/]+$) ],
    );
    for my $event ( $watcher->new_events ) {
        print $event->path, ' - ', $event->type, "\n";
    }

DESCRIPTION

This class provides information about a change to a specific file or directory.

METHODS

File::ChangeNotify::Event->new(...)

This method creates a new event. It accepts the following arguments:

  • path => $path

    The full path to the file or directory that changed.

  • type => $type

    The type of event. This must be one of "create", "modify", "delete", or "unknown".

$event->path

Returns the path of the changed file or directory.

$event->type

Returns the type of event.

$event->has_attributes

This returns true for modify events which include information about a path's attribute changes.

$event->attributes

If the event includes information about changes to a path's attributes, then this returns a two-element arrayref. Each element is in turn a hashref which will contain at least one of the following keys:

  • permissions

    The permissions mask for the path.

  • uid

    The user id that owns the path.

  • gid

    The group id that owns the path.

Note that only keys which changed will be included.

$event->has_content

This returns true for modify events which include information about a file's content.

$event->content

This returns a two-element arrayref where the first element is the old content and the second is the new content.

Note that this content is stored as bytes, not UTF-8. You will need to explicitly call "Encode::decode" on the content to make it UTF-8. This is done because there's no reason you couldn't use this feature with file's containing any sort of binary data.
