Subject: Re: [Rails] FileSystemWatcher - has any one done this?

FreeBSD has kqueue, and Windows has a built-in feature as well. I’ve
done several polling routines using the opendir() syscall, and much
prefer kqueue. Webservers have well-written internal methods, but I
don’t know if they expose an API.

But the question remains “how to do it in a platform-independant way
from Ruby”. Polling will work, but if you want low-latency
notification, you’ll burn cpu.

There’s Ara Howard’s ‘dirwatch’ package on the RAA:

http://raa.ruby-lang.org/project/dirwatch/

I’ve never used it myself, however.

HTH,

Dan
