hinotify 0.1

Initial release

API

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

Download

The code is available via the homepage, and via darcs:

darcs get --partial http://haskell.org/~kolmodin/code/hinotify/

The API is available online.

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