About

This package provides bindings to inotify, which has been part of the Linux kernel since 2.6.13.

The inotify subsystem provides file system event notifications. Simply add a watcher to a file or directory and you get events when it is accessed, modified, etc.

News

See CHANGELOG.md.

API

The API basically consists of:

initINotify :: IO INotify

addWatch :: INotify
         -> [EventVariety]   -- different events to listen on
         -> RawFilePath      -- file/directory to watch
         -> (Event -> IO ()) -- event handler callback
         -> IO WatchDescriptor

removeWatch :: WatchDescriptor -> IO ()

See this example or the docs.

Changes

hinotify

0.4.2

0.4.1

  • Depend on inotify library on {Free,Open}BSD

0.4

  • Allow async-2.*

0.3.10

  • Allow async-2.2.

  • Use RawFilePath (ByteString) for filenames, from unix package.

    Changes the Event type and addWatch function.

0.3.9

Patches contributed by Simon Marlow [email protected]

  • Don’t run callbacks in mask_.

    It prevented the callback threads from receiving StackOverflow, amongst other things.

  • Synchronous killThread.

    killThread will now wait for the callback dispatcher threads to finish.

  • Bug fixes

    https://github.com/kolmodin/hinotify/pull/23

0.3.8

  • Use file system encoding for file names.

    When run in a locale like LANG=C, this ensures that the filename is encoded as a filename, so that arbitrary bytes in it will round-trip correctly, rather than being stripped out.

    Fixes https://github.com/kolmodin/hinotify/issues/13

    Patch contributed by Joey Hess [email protected]

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.

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

0.3.1

  • Use inotify.h from glibc rather than from the linux headers, as recommended upstream.

0.3

  • Compiles with GHC 6.12, GHC 6.10.4, GHC 6.8.2 and GHC 6.6.1

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

0.1

  • Initial release
