watchman: the hero your filesystem needs

Build Status

A Clojure library providing a facade for Java's WatchService.

Usage

Pull the depenency with leiningen (add this in your project.clj)

[spootnik/watchman "0.3.7"]
(watch.man/watch!
  "/some/dir"
  (fn [event] (println (pr-str event))))

watch! accepts an optional map argument with the following keys:

  • event-types: a collection of any keywords from :create, :modify, :delete

watch! returns the underlying WatchService, watch.man/close can be called on the service.

Each argument to the callback when using watch! will be a map with the following keys:

  • type: :path, :exception or :closing
  • path: The path a :path event happens on
  • types: The types of event a :path event was triggered for
  • srv: The watch service
  • exception: The exception that was raised for :exception events.
