support OMEMO

[jelmer]

It would be great to support OMEMO. This depends on support in slixmpp: https://lab.louiz.org/poezio/slixmpp/merge_requests/1

Hello,
added omemo support here https://github.com/ichthyx/prometheus-xmpp-alerts
I'll do a pr when I have time

@ichthyx: Any news on it? :)

[ichthyx]

It's on my todo list but for now I lack of time sorry.
If you in a hurry, you can get a working version in some branch, but code was not perfect.

@jelmer is master supposed to work?

I have a bunch of error like

    help=argparse.HIDDEN)
         ^^^^^^^^^^^^^^^
AttributeError: module 'argparse' has no attribute 'HIDDEN'

UnboundLocalError: cannot access local variable 'text' where it is not associated with a value

in render_alert

and recipients bugs user@domain become 'u'

btw here an example with the new omemo plugin from Syndace

[jelmer]

Yeah, not sure how that regressed. I've fixed it up and added some tests for the argument parsing.
