noticeme 2018.12

Provides a framework for building watchers. Includes a watcher utility program that allows you to create watchers declaratively.

noticeme

Provides python bindings for inotify and framework for building watchers using coroutines.

Please note this only runs on Linux and a have no plans to support any other OS.

There are many, many alternatives though.

noticeme includes the noticeme command for quickly setting up a file watcher.

Using noticeme declaratively

If you just need a small file watcher you can try this out.

pip install --user noticeme # install
nano noticeme.cfg # use noticeme/examples/noticeme.cfg for an example
noticeme # start watching

To see a full list of events:

  noticeme events

Quick look at configuration

see noticeme/examples/noticeme.cfg for details

# noticeme.cfg
[should]
  clear_screen = yes

[imports]
  example = A .py file with a @noticeme.watcher decorator in it

[my_watcher]
  description = This is an example.
  paths = . **
  events = written
  regex = ^docs
  glob = *.txt
  shell = echo "my_watcher: file was added"

Using noticeme to build a file watcher programmatically

import asyncio
import noticeme

@noticeme.watcher('/path/to/directory', 'created modified')
async def my_watcher(event):
  if '.py' == event.path.suffix.lower():
    proc = await asyncio.create_subprocess_exec('cmd', event.path.absolute())
    await proc.wait()

if __name__ == '__main__':
  noticeme.run()

Requirements

• Linux >= 2.6.13
• Python >= 3.5
• cffi
• C compiler installed (if you need to run inotify_build.py)

Install

pip

pip install --user noticeme

Include directly

• Copy noticeme.py and inotify_build.py to your project directory
• Within noticeme's package directory run:

python3 inotify_build.py

• This creates a 'build' directory containing the result of ffibuilder.compile
• You should now be able to use noticeme.
• inotify_build.py will no longer be needed.
