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.

Cheers,
