Filesys::Notify::Simple − 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 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. |
