Minimalistic Open Sound Control (OSC) communication module using asyncio

Project Description

This is an experimental minimalistic Open Sound Control (OSC) communication module which uses asyncio for network operations and is compatible with the asyncio event loop.

Installation

aiosc requires at least Python 3.4. It can be installed using pip:

pip3 install aiosc
pip3 install --user aiosc

Usage

To send an OSC message just use aiosc.send:

import asyncio
import aiosc

loop = asyncio.get_event_loop()
loop.run_until_complete(
    aiosc.send(('127.0.0.1', 9000), '/hello', 'world')
)

To implement an OSC server with aiosc you should create an UDP endpoint using aiosc.OSCProtocol as the protocol. OSCProtocol can be subclassed or directly constructed with a dictionary mapping OSC address patterns to handler methods for incoming messages:

def protocol_factory():
    osc = aiosc.OSCProtocol({
        '//*': lambda addr, path, *args: print(addr, path, args)
    })
    return osc

loop = asyncio.get_event_loop()
coro = loop.create_datagram_endpoint(protocol_factory, local_addr=('127.0.0.1', 9000))
transport, protocol = loop.run_until_complete(coro)

loop.run_forever()

For more examples, see examples/.

OSC address patterns

aiosc dispatches messages to handler methods using glob-style address pattern matching as described in the OSC 1.0 specification. The // operator from OSC 1.1 preliminary specification is also supported.

Examples:

  • /hello/world matches /hello/world.
  • /hello/* matches /hello/world and /hello/sarah.
  • /{hello,goodbye}//world matches /hello/world and /goodbye/cruel/world.
  • //* matches any address.

Notes

Bundles are not yet supported.

Contrary to most OSC implementations, OSC data types are picked from the preliminary spec documented in Features and Future of Open Sound Control version 1.1 for NIME paper. For example, ‘I’ typetag is decoded to Impulse (aka “bang”) which is passed around as aiosc.Impulse singleton.

Suggestions, bug reports, issues and/or pull requests are, of course, welcome.
