Ohhh, that might come in handy. I will probably test it soon. Thanks!

I’m having some troubles getting it up and running. It’s been a while since I messed with python, so please bear in mind if I might be doing something silly :)

The error I’m getting is this:

Projects/Sandbox/nbxmpp-client nbxmpp-client-xYpYLqyi took 10s 
➜ nbc
Traceback (most recent call last):
  File "/home/marcosdevera/.local/bin/nbc", line 5, in <module>
    from nbxmpp_client.main import run

  File "/usr/lib/python3/dist-packages/gi/__init__.py", line 129, in require_version
    raise ValueError('Namespace %s not available for version %s' %
ValueError: Namespace GtkSource not available for version 5

What I did to get there?

Projects/Sandbox/nbxmpp-client 
➜ pipenv --python 3.10
...
Projects/Sandbox/nbxmpp-client 
➜ pipenv shell
...
Projects/Sandbox/nbxmpp-client nbxmpp-client-xYpYLqyi 
➜ pip install nbxmpp-client

I have the following (I think) relevant system packages installed:

Thanks in advance!

@marcos looks like you're missing gir1.2-gtksource-5

Thanks a lot! That led me a step further, but now I get this:

you need libadwaita 1.2 (but your system offers 1.1). You're welcome to join xmpp:gajim@conference.gajim.or… for help!

@marcos An appimage would be handy, I'm having all the same problems and this is a tool most people will not use on a regular basis.
