APRSD Command Plugin Development
|
|
================================
|
|
|
|
APRSDPluginBase
|
|
------------------------
|
|
|
|
Plugins are written as python objects that extend the APRSDPluginBase class.
|
|
This is an abstract class that has several properties and a method that must be implemented
|
|
by your subclass.
|
|
|
|
Properties
|
|
----------
|
|
|
|
* name - the Command name
|
|
* regex - The regular expression that if matched against the incoming APRS message,
|
|
will cause your plugin to be called.
|
|
|
|
Methods
|
|
-------
|
|
|
|
* command - This method is called when the regex matches the incoming message from APRS.
|
|
If you want to send a message back to the sending, just return a string
|
|
in your method implementation. If you get called and don't want to reply, then
|
|
you should return a messaging.NULL_MESSAGE to signal to the plugin processor
|
|
that you got called and processed the message correctly. Otherwise a usage
|
|
string may get returned to the sender.
|
|
|
|
|
|
Example Plugin
|
|
--------------
|
|
|
|
There is an example plugin in the aprsd source code here:
|
|
aprsd/examples/plugins/example_plugin.py
|
|
|
|
.. code-block:: python
|
|
|
|
import logging
|
|
|
|
from aprsd import plugin
|
|
|
|
LOG = logging.getLogger("APRSD")
|
|
|
|
|
|
class HelloPlugin(plugin.APRSDRegexCommandPluginBase):
|
|
"""Hello World."""
|
|
|
|
version = "1.0"
|
|
# matches any string starting with h or H
|
|
command_regex = "^[hH]"
|
|
command_name = "hello"
|
|
|
|
def process(self, packet):
|
|
LOG.info("HelloPlugin")
|
|
reply = "Hello '{}'".format(packet.from_call)
|
|
return reply
|
