I've used Powerlevel10k for ages (https://github.com/romkatv/powerlevel10k), but it seems it's no longer actively developed / maintained. I think it's a lot cleaner, how I have it set up right now it shows some information like timestamp, Ruby versions, command runtime etc on the right side, whereas Starship shows it right at the prompt.
Starship only supports this in PowerShell for whatever reason.
Edit: Doh. I see what you linked to now. Yea, maybe it does work in more than just PowerShell now?
Transient prompt basically removes your prompt decorations and replaces it with just `>` in your scroll back history in your shell sessions. In my case it's a slightly more complex transient prompt (datetime and exit code of the command), but still greatly simplified.
Makes cut-and-paste of history in to docs and stuff super nice.
oh, wow, didn't realize powerlevel10k was no longer maintained. that's a bummer. I liked it better than Starship last time I yak-shaved my local cli workflow.
