hinotify, a library to inotify which has been part of the Linux kernel since 2.6.13.
inotify provides file system event notification, simply add a watcher to a file or directory and get an event when it is accessed or modified.
This module is named

glibcrather than from the linux headers, as recommended upstream.
The API basically consists of:
initINotify :: IO INotify addWatch :: INotify -> [EventVariety] -- different events to listen on -> FilePath -- file/directory to watch -> (Event -> IO ()) -- event handler -> IO WatchDescriptor removeWatch :: INotify -> WatchDescriptor -> IO ()
A sample program:
import System.Directory import System.IO import System.INotify main :: IO () main = do inotify <- initINotify print inotify home <- getHomeDirectory wd <- addWatch inotify [Open,Close,Access,Modify,Move] home print print wd putStrLn "Listens to your home directory. Hit enter to terminate." getLine removeWatch inotify wd
The code is available via the homepage, and via darcs:

The API is available online.
I’m most grateful for feedback on the API, and what else you might have to suggest.
