Overview

Filesys::Notify::Simple is a simple but unified interface to get notifications of changes to a given filesystem path. It utilizes inotify2 on Linux, fsevents on OS X, kqueue on FreeBSD and FindFirstChangeNotification on Windows if they're installed, with a fallback to the full directory scan if they're not available.

There are some limitations in this module. If you don't like it, use File::ChangeNotify.

In return, this module doesn't depend on any non-core modules. Platform specific optimizations with Linux::Inotify2, Mac::FSEvents, Filesys::Notify::KQueue and Win32::ChangeNotify are truely optional.

NOTE: Using Win32::ChangeNotify may put additional limitations.

•

Win32::ChangeNotify uses FindFirstChangeNotificationA so that Unicode characters can not be handled. On cygwin (1.7 or later), Unicode characters should be able to be handled when Win32::ChangeNotify is not used.

•

If more than 64 directories are included under the specified paths, an error occurrs.
