Description:
Ruby library listening to file modifications
This Ruby library listens to file modifications and notifies you about the changes. . It detects file modification, addition and removal, and supports multiple directories from a single listener. It uses checksum comparison for modifications made under the same second, and allows supplying regexp-patterns to ignore and filter paths for better results.
