This module provides support for Twisted to linux inotify API.

In order to use this support, simply do the following (and start a reactor at some point):

   from twisted.internet import inotify
   from twisted.python import filepath

   def notify(ignored, filepath, mask):
       """
       For historical reasons, an opaque handle is passed as first
       parameter. This object should never be used.

       @param filepath: FilePath on which the event happened.
       @param mask: inotify event as hexadecimal masks
       """
       print("event %s on %s" % (
           ', '.join(inotify.humanReadableMask(mask)), filepath))

   notifier = inotify.INotify()
   notifier.startReading()
   notifier.watch(filepath.FilePath("/some/directory"), callbacks=[notify])
   notifier.watch(filepath.FilePath(b"/some/directory2"), callbacks=[notify])

Note that in the above example, a FilePath which is a bytes path name or str path name may be used. However, no matter what type of FilePath is passed to this module, internally the FilePath is converted to bytes according to sys.getfilesystemencoding. For any FilePath returned by this module, the caller is responsible for converting from a bytes path name to a str path name.

Present Since10.1
Function humanReadableMask Auxiliary function that converts a hexadecimal mask into a series of human readable flags.
Class INotify The INotify file descriptor, it basically does everything related to INotify, from reading to notifying watch points.
Class _Watch Watch object that represents a Watch point in the filesystem. The user should let INotify to create these objects
def humanReadableMask(mask): (source)

Auxiliary function that converts a hexadecimal mask into a series of human readable flags.
