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 and fsevents on OS X 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 the File::ChangeNotify manpage.

• 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 the Linux::Inotify2 manpage and the Mac::FSEvents manpage are truely optional.
