About
-----
Asynchronous messaging using python's new facility(async-await syntax), introduced in version 3.5 is so fun!
So, I decided to provide an asynchronous context manager and iterator wrapper for
`Linux Infra-Red Remote Control(LIRC) <http://www.lirc.org/>`_.
Happily, the Cython is working well with asyncio. So the `lirc_client` C extension has been made by cython's extenstion
type.
In addition, an `IRCDispatcher` type and a `listen_for` decorator have been provided.
Install
-------
::
$ apt-get install liblircclient-dev python3.5-dev build-essential
$ pip install cython
$ pip install aiolirc
Quick Start
-----------
The simplest way to use this library is the famous `very_quickstart` function as follows::
from aiolirc import very_quickstart, listen_for
@listen_for('play')
async def do_play(loop):
...
# Do play stuff
very_quickstart('my-prog') # my-prog is configured in your lircrc file.
Another coroutine function named `quickstart` is also available.This lets you have control over the event loop
life-cycle::
import asyncio
from aiolirc import quickstart
main_loop = asyncio.get_event_loop()
try:
main_loop.run_until_complete(quickstart(loop=main_loop))
except KeyboardInterrupt:
print('CTRL+C detected. terminating...')
return 1
finally:
if not main_loop.is_closed():
main_loop.close()
The `IRCDispatcher`
-------------------
Constructor
^^^^^^^^^^^
::
def __init__(self, source: LIRCClient, loop: asyncio.BaseEventLoop=None):
Example of usage
^^^^^^^^^^^^^^^^
::
import asyncio
from aiolirc.lirc_client import LIRCClient
from aiolirc.dispatcher import IRCDispatcher, listen_for
@listen_for('amp power', repeat=5)
async def amp_power(loop):
...
# Do your stuff
@listen_for('amp source')
async def amp_source(loop):
...
# Do your stuff
async with LIRCClient('my-prog') as client:
dispatcher = IRCDispatcher(client)
await dispatcher.listen()
The `LIRCClient`
----------------
Constructor
^^^^^^^^^^^
::
def __cinit__(self, lircrc_prog, *, lircrc_file='~/.config/lircrc', loop=None, check_interval=.05, verbose=False,
blocking=False):
To advance control over the messages received from lirc, asychronously iter over an instance of the `LIRCClient` after
calling `LIRCClient.lirc_init()`. And make sure the `LIRCClient.lirc_deinit()` has been called after finishing your work
with `LIRCClient`::
from aiolirc.lirc_client import LIRCClient
client = LIRCClient('my-prog')
try:
client.lirc_init()
async for cmd in client:
print(cmd)
finally:
client.lirc_deinit()
You may use the `LIRCClient` as an asynchronous context manager as described as follows, to automatically call the
`LIRCClient.lirc_init()` and `LIRCClient.lirc_deinit()` functions, and also acquiring a lock to prevent multiple
instances of the `LIRCClient` from reading messages from lirc_client wrapper::
from aiolirc.lirc_client import LIRCClient
async with LIRCClient('my-prog') as client:
async for cmd in client:
print(cmd)
Systemd
-------
Create a main.py::
import sys
import asyncio
from aiolirc import IRCDispatcher, LIRCClient
async def launch(self) -> int:
async with LIRCClient('my-prog', lircrc_file='path/to/lircrc', check_interval=.06) as client:
dispatcher = IRCDispatcher(client)
result = (await asyncio.gather(dispatcher.listen(), return_exceptions=True))[0]
if isinstance(result, Exception):
raise result
return 0
def main(self):
main_loop = asyncio.get_event_loop()
try:
return main_loop.run_until_complete(launch())
except KeyboardInterrupt:
print('CTRL+C detected.')
return 1
finally:
if not main_loop.is_closed():
main_loop.close()
if __name__ == '__main__':
sys.exit(main())
