I'm getting the same error.

[jwoglom]

Sounds like the same issue as @7, just applied to Python 3.8 rather than 3.7.

Can you try my fork of npyscreen (https://github.com/jwoglom/npyscreen) which on line 18 of apNPSApplicationEvents.py does not have an explicit "raise StopIteration"?

Will try your fork in a little bit. Thanks!

[reardenlife]

@jwoglom

Alright. Your fork worked out good, I can see the interface. Yet I am unable to find any documentation. It is unclear for example how to add a new contact (I've got 0 right now).

[jwoglom]

@reardenlife The contacts list piggybacks off of the contacts which are delivered to it via Signal. so if you have the application on your phone, then any contacts/threads should hopefully appear.

If not, I imagine you can manually add to the JSON in .local/share/signal-cli/data/+1your_phone (or wherever your data folder is) with something like:

"contactStore" : {
  "contacts" : [ {
    "name" : "[contact name]",
    "number" : "+1[phone]",
    "color" : "blue_grey",
    "profileKey" : "[some weird base64'd data, I think this can be set as a raw JSON null]"
  }, [..]

Don't know where to go from here. Using macos.

[jwoglom]

@WangElectronics I have not been able to get dbus working properly on macos in some time -- it is quite finicky. Not sure where to lead you from there. Make sure you're running a dbus server on your machine.
