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.
