How to work with Python 3.8?

[spamegg1]

Hi @manipuladordedados ,
I was looking for some open source projects to contribute, and came across this while browsing on Code Triage.
I want to contribute but I guess it's been 2 years since the last activity.
I tried running pdiary and came across errors. I guess some of the dependency packages are not maintained up to Python 3.8.
Here is the error I get:

$ pdiary
Traceback (most recent call last):
  File "/usr/local/lib/python3.8/dist-packages/npyscreen/apNPSApplicationEvents.py", line 16, in get
    yield self.interal_queue.pop()
IndexError: pop from an empty deque

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/local/lib/python3.8/dist-packages/npyscreen/apNPSApplicationEvents.py", line 18, in get
    raise StopIteration
StopIteration

I went to npyscreen/apNPSApplicationEvents.py and changed line 18 from raise StopIteration to return.
Then I am able to run pdiary a bit. I get the password prompt. Type my password twice, hit Enter. Then it crashes again with the following error:

pdiary

    conn = sqlcipher.connect(self.database, isolation_level=None, **params)
TypeError: 'kdf_iter' is an invalid keyword argument for this function

Any idea how I can progress? Or should I just abandon the idea of working on this? What other up to date packages can be used instead?

Fixed.
