directory\_watcher version 1.2.0  
by Tim P.  
[http://codeforpeople.rubyforge.org/directory\_watcher](http://codeforpeople.rubyforge.org/directory_watcher)

== DESCRIPTION

## The directory watcher operates by scanning a directory at some interval and generating a list of files based on a user supplied glob pattern. As the file list changes from one interval to the next, events are generated and dispatched to registered observers. Four types of events are supported

added, modified, stable, and removed.

== CHANGES

- 2 minor enhancements
  - added an option to persist state to a file [Benjamin T.]
  - the option to run the directory watcher scanner manually  
(i.e. one loop at a time)

Hi,

directory\_watcher sounds like the ideal candidate to make use of  
filesystem event notifications such as those provided by inotify or  
fsevents. Are there any plans for this in a future version of  
directory\_watcher?

Regards,

Denis

Note that such a thing would be fairly trivial to add to Rev, as libev  
already supports a cross-platform API for directory monitoring which  
uses  
inotify on Linux:
