Monitoring folder for changes

Ruby
1

Is there any gem or code example that would help me to watch a given
folder for changes and trigger a callback upon change detection?

Thanks!

If speed is more important than portability, you may want to consider
utilizing operating specific features. I believe Linux, OSX & Windows
all provide notifications of changes to the file system so you wouldn’t
have to periodically poll.
