NAME

6       Filesys::Notify::Simple - Simple and dumb file system watcher
7

SYNOPSIS

9         use Filesys::Notify::Simple;
10
11         my $watcher = Filesys::Notify::Simple->new([ "." ]);
12         $watcher->wait(sub {
13             for my $event (@_) {
14                 $event->{path} # full path of the file updated
15             }
16         });

DESCRIPTION

19       Filesys::Notify::Simple is a simple but unified interface to get
20       notifications of changes to a given filesystem path. It utilizes
21       inotify2 on Linux, fsevents on OS X, kqueue on FreeBSD and
22       FindFirstChangeNotification on Windows if they're installed, with a
23       fallback to the full directory scan if they're not available.
24
25       There are some limitations in this module. If you don't like it, use
26       File::ChangeNotify.
27
28       •   There is no file name based filter. Do it in your own code.
29
30       •   You can not get types of events (created, updated, deleted).
31
32       •   Currently "wait" method blocks.
33
34       In return, this module doesn't depend on any non-core modules. Platform
35       specific optimizations with Linux::Inotify2, Mac::FSEvents,
36       Filesys::Notify::KQueue and Win32::ChangeNotify are truely optional.
37
38       NOTE: Using Win32::ChangeNotify may put additional limitations.
39
40       •   Win32::ChangeNotify uses FindFirstChangeNotificationA so that
41           Unicode characters can not be handled.  On cygwin (1.7 or later),
42           Unicode characters should be able to be handled when
43           Win32::ChangeNotify is not used.
44
45       •   If more than 64 directories are included under the specified paths,
46           an error occurrs.
