Plug of basically the same idea except as a pip package:

https://github.com/Aperocky/diarycli

`pip install diarycli`

Alternatively there is a shell version if you are averse to python/pip package manager as well:

https://github.com/Aperocky/diaryman/blob/master/diaryman.sh

I've been using this for years, it doesn't have any fancy features - it only reliably opens up/create today's diary in vim whenever I type `diary` in command line. with some minor utilities.

It is life changing - having `diary` where I can type my thoughts into whenever. I maintain a separate one both for work and life - and both are proving invaluable.
