Gyr

Come talk with us about Gyr on matrix at #gyr:matrix.org!

Gyr is a framework for quickly developing matrix application services in python3. It provides a WSGI application and several other utilities for working with matrix.

Gyr is designed to be a fairly thin layer of abstraction over application service api--just enough to make things easy without pushing you so far from the spec that you get confused.

Status

Gyr hasn't been worked on in months. For a python application-service framework under more active development I recommend checking out Cadair's python-appservice-framework. Use at your own risk currently, and be especially aware of bugs like this one caused by Gyr's lack of asynchronicity. I hope to return to this framework once I land async in matrix-python-sdk.

Very alpha! Most of the main functionality I'd envisioned is present, however there's poor to non-existent documentation and no unit tests. Contributions are welcome.

Installation

Please install gyr with pip (in a virtualenv if you prefer):

pip install gyr

Usage

I'll try to show a bunch of functionality here, but see examples directory for further usage examples.

from gyr import server, matrix_objects

application = server.Application("http://localhost:8008", "foobar")

as_user = matrix_objects.MatrixUser("@example_as:example.com", application.Api)
room = as_user.create_room(alias="#foo:example.com", is_public=True)

def rm_hndlr(room_id):
    # Gyr will create a user for you if this returns true!
    return False
    
def user_hndlr(user_id):
    # Gyr will create the room for you if this returns true!
    return False
    
def txn_hndlr(events):
    for event in events:
    	room.send_notice(
	    "Received event type {} in room {} from user {}".format(event.type,
	                                                            event.room,
								    event.user)
	)
    return True
	
application.add_handlers(room_handler=rm_hndlr, transaction_handler=txn_hndlr,
                         user_handler=user_hndlr)

Save as example.py. Then from the commandline:

gunicorn example:application

Modules

gyr.server

server provides the WSGI application class. An instance of gyr.server.Application functions as the WSGI app and will automatically parse the request and call any handlers provided to the Application instance.

gyr.api

api provides a helpful wrapper for matrix-python-sdk's api, changing the parts of the api that are different for application services until such time as similiar changes are merged upstream. Pull requests for these changes have been submitted, and some changes already merged into master.

For working with the api, I recommend using the wrappers built around specific objects which are available in gyr.matrix_objects.

gyr.matrix_objects

matrix_objects provides helpful wrapper classes around matrix users, events and rooms. It is not designed to be easily used for the normal client-server api but should provide most necessary functionality for the manipulation of users and rooms that an application service might need to do.

Pull requests enriching the functionality of these classes are very welcome.
