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 hinotify
.
See example code in the examples
directory, distributed with the source
code.

hinotify 0.1 : Initial release
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 :: 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 wd
The code is available via the homepage, and via darcs:
git clone https://github.com/kolmodin/hinotify.git
The API is available online.
I'm most grateful for feedback on the API, and what else you might have to suggest.
