There were some requests to make a powerline prompt for manjaro-zsh-config some years ago. I made one, but I didn’t have time to upload it before my computer broke. However, I found that powerline 10k is better anyway. More features, better performance and more customization.
Powerline would be enabled only for terminals and disabled for TTY for compatibility reasons.
If it is just for the prompt I believe powerline is overkill.
I am using this customized theme for zsh:
if [[ $UID -eq 0 ]];
And it looks like this:
I find it important to see the username, the hostname and the working directory on a separate line so that there is a full line available for long commandlines. And the color coding is for convenience. With different colors for the root user.
I wanted to upload a screenshot of it, but I am not allowed to add a “media file” to this post. Hmmm.
