NAME

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

SYNOPSIS

         use Filesys::Notify::Simple;

         my $watcher = Filesys::Notify::Simple->new([ "." ]);
         $watcher->wait(sub {
             for my $event (@_) {
                 $event->{path} # full path of the file updated
             }
         });

DESCRIPTION

       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.

       •   There is no file name based filter. Do it in your own code.

       •   You can not get types of events (created, updated, deleted).

       •   Currently "wait" method blocks.

       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.
