iaw4 has asked for the wisdom of the Perl Monks concerning the following question:

there are a number of nice packages on cpan for monitoring files in a cross-OS portable fashion, such as File::Monitor, or File::ChangeNotify, or AnyEvent::Filesys::Notify. I believe, for real-time quick notifications, they rely on Mac::FSEvents. Otherwise, they fall back to very slow scanning.

the problem is that Mac::FSEvents no longer compiles on osx yosemite. there are now errors in FSEvents.xs. probably a change in OSX.

is there a different cpan module recommended that provides immediate notification of file changes? I just need a simple blocking call on a few files with a callback.

Replies are listed 'Best First'.

    I don't use OSX but perhaps if you posted the errors someone might be able to fix them. At the very least you can report this as an issue on
