hinotify: inotify for Haskell
About
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.
News
hinotify 0.3.7
- Bug fix: When registerering a new watch on a path which is already watched,
don’t overwrite the event listener from the previous watch.
hinotify 0.3.2
- Make each
WatchDescriptor
contain its INotify
. Changes to the function types:
-removeWatch :: INotify -> WatchDescriptor -> IO ()
+removeWatch :: WatchDescriptor -> IO ()
- Fix typo in declaration of
Deleted
in data Event
;
- { isDirecotry :: Bool
+ { isDirectory :: Bool
hinotify 0.3.1
- Use
inotify.h
from glibc
rather than from the linux headers, as
recommended upstream.
hinotify 0.3
- Compiles with GHC 6.12, GHC 6.10.4, GHC 6.8.2 and GHC 6.6.1
hinotify 0.2
- Updates to the API
- Function names is now in semiCamelCase
- Restructure event parameters to make it more consistent
- Small test suit in
tests/
- Compiles with GHC 6.8.2 and GHC 6.6.1
- Requires Cabal 1.2
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 :: 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
Download
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.
