aionotify
aionotify is a simple, asyncio-based inotify library.
Its use is quite simple:
import asyncio
import aionotify
# Setup the watcher
watcher = aionotify.Watcher()
watcher.watch(alias='logs', path='/var/log', flags=aionotify.Flags.MODIFY)
async def work():
await watcher.setup()
for _i in range(10):
# Pick the 10 first events
event = await watcher.get_event()
print(event)
watcher.close()
asyncio.run(work())Links

Events
An event is a simple object with a few attributes:
-
name: the path of the modified file -
flags: the modification flag; useaionotify.Flags.parse()to retrieve a list of individual values. -
alias: the alias of the watch triggering the event -
cookie: for renames, this integer value links the "renamed from" and "renamed to" events.
Watches
aionotify uses a system of "watches", similar to inotify.
A watch may have an alias; by default, it uses the path name:
watcher = aionotify.Watcher()
watcher.watch('/var/log', flags=aionotify.Flags.MODIFY)
# Similar to:
watcher.watch('/var/log', flags=aionotify.Flags.MODIFY, alias='/var/log')A watch can be removed by using its alias:
watcher = aionotify.Watcher()
watcher.watch('/var/log', flags=aionotify.Flags.MODIFY)
watcher.unwatch('/var/log')
