Very simple way of controlling your Python application via Slack.

Yasuf consists of a single, simple decorator that allows you to execute the decorated function via Slack and get it's output back, without modifying the function in any way.

Let's say you have a function say_hello that takes a single integer argument, prints out "Hello!" that many times and returns string describing how many times it has done so:

def say_hello(count):
    for i in range(count):
        print("Hello!")
    return "I've just said Hello! {} times!".format(count)

Controlling this function is as simple as decorating it with the yasuf.handle decorator:

from yasuf import Yasuf

yasuf = Yasuf('slack-token', channel='#general')

The first argument is your token which you can get here and channel specifies the default channel Yasuf will be listening to.

@yasuf.handle('Say hello ([0-9]+) times!', types=[int])
def say_hello(count):
    (...)

The first argument of handle specifies the regexp that the function should respond to, where each capture group corresponds to one argument of the decorated function and types is a list of functions that will be applied to the captured arguments to convert them from string to whatever the decorated function expects.

Now you can run (or run_async).

yasuf.run()

From now on whenever you type Say hello 3 times! Yasuf will response with a couple hellos. Or you can ask Yasuf what he knows with the built-in function 'help'.

python3 -m pip install --user yasuf
