Filesys...::Simple(3)

Okay bestie, welcome to the Filesys::Notify::Simple page from the User Contributed Perl Documentation 💅 — you’ll find it filed under Filesys...::Simple(3), and it’s literally a simple and dumb file system watcher. Let’s get into it ✨

🌸 NAME 🌸

Filesys::Notify::Simple — a simple and dumb file system watcher 🎀

✨ SYNOPSIS ✨

Here’s the whole vibe, copied exactly so you can steal it:

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 🦋

So 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 — that’s the official escape hatch 🫶

• There is no file name based filter — do it in your own code, bestie.
• You can not get types of events (created, updated, deleted).
• Currently the wait method blocks.

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