Greetings! I'm pleased to announce hinotify 0.1, a library to inotify[1] 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. The API basically consists of: inotify_init :: IO INotify inotify_add_watch :: INotify -> [EventVariety] -- different events to listen on -> FilePath -- file/directory to watch -> (Event -> IO ()) -- event handler -> IO WatchDescriptor inotify_rm_watch :: INotify -> WatchDescriptor -> IO () A sample program:

import System.Directory import System.IO

import System.INotify

main :: IO () main = do inotify <- inotify_init print inotify home <- getHomeDirectory wd <- inotify_add_watch inotify [Open,Close,Access,Modify,Move] home print print wd putStrLn "Listens to your home directory. Hit enter to terminate." getLine inotify_rm_watch inotify wd

The code is available via www: http://haskell.org/~kolmodin/code/hinotify/download/hinotify-0.1.tar.gz and via darcs: darcs get http://haskell.org/~kolmodin/code/hinotify/ The API is available at: http://haskell.org/~kolmodin/code/hinotify/docs/api/ The library is very young and I'm most grateful for feedback on the API, and what else you might have to suggest.
