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.
