Description:
ubus 0.1.2
Code in this directory enables a subset of libubus functions to be used directly from python.
Installation
To install these bidning you need to have the following libraries and headers installed:
libubox
libubus
python/python3
Examples
connect and disconnect
To connect you need to:
import ubus
ubus.connect("/var/run/ubus/ubus.sock")
To disconnect you can simply:
ubus.disconnect()
Note that calling connect()/disconnect() on opened/closed connection will throw an exception.
add
To add an object to ubus you can (you need to become root first):
def callback(handler, data):
handler.reply(data) # this should return exactly the same data to the caller
ubus.add(
"my_object", {
"my_method": {"method": callback, "signature": {
"first": ubus.BLOBMSG_TYPE_STRING,
"second": ubus.BLOBMSG_TYPE_BOOL,
"third": ubus.BLOBMSG_TYPE_INT32,
}},
},
)
You need to enter the loop to serve the object methods afterwards:
ubus.loop()
Note that it might not be a good idea to call the callback function recursively.
objects
To list the objects which are currently connected to ubus you can call:
ubus.objects()
->
{u'my_object': {u'my_method': {u'first': 3, u'second': 7, u'third': 5}}}
call
To call an actual method on an object you can use:
ubus.call("my_object", "my_method", {"first": "my_string", "second": True, "third": 42})
->
[{"first": "my_string", "second": True, "third": 42}]
listen
To listen for an event you can:
def callback(event, data):
print(event, data) # just print event name and data to stdout
ubus.listen(("my_event", callback))
And you need to enter the loop to start to listen:
ubus.loop()
Note that it might not be a good idea to call the callback function recursively.
send
This will send an event to ubus:
ubus.send("my_event", {"some": "data"})
Notes
There are some tests present (‘tests/’ directory). So feel free to check it for some more complex examples.
To run the tests you need to have ubus installed and become root:
sudo python setup.py test
