Simple and dumb file system watcher
use Filesys::Notify::Simple;
my $watcher = Filesys::Notify::Simple->new([ "." ]);
$watcher->wait(sub {
for my $event (@_) {
$event->{path} # full path of the file updated
}
});
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 \s-1OS\s0 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 \*(C`wait\*(C' 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.
\s-1NOTE:\s0 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.
