bluefin-cli bling not working correctly when using zsh as described in docs

[TheItsNameless]

Describe the bug

I have tried to activate zsh with bluefin-cli using the steps in the documentation:

https://docs.projectbluefin.io/command-line/#terminal-configuration

However, there is an error:

atuin: requires bash >= 3.1 for the integration.
(eval):140: command not found: shopt

I have pinned down the problem to a bug in the /usr/share/ublue-os/bling/bling.sh, where the code checks for the login shell using $(basename "$SHELL") == "zsh", but since the documentation explicitly told me to not change the system shell and only the emulated shell the login shell stays at bash and the command atuin init bash is run in zsh.

What did you expect to happen?

The if-statement in /usr/share/ublue-os/bling/bling.sh should correctly check for the current shell with $0 instead of the login shell.

Also i have tested with $(basename "$0") and it returns bling.sh so this is not the solution either. My current workaround is using $ZSH_NAME as this is only set in zsh.

Ok so I didn't know about this doc and I use fish myself and I changed the user's default shell to fish (oops). I do see what you are talking about on my test instance and was able to reproduce. I also have a good way to grab the current running shell someone is using when the default $SHELL env will still be set to /bin/bash. I will see if I can get it fixed up on the ujust call to make this work for ZSH better in the future.

For reference it looks like someone else has had this issue here: ublue-os/packages#131

There is a PR related to this as well but I think its stale so I might just push in a new option: ublue-os/packages#536

I was able to confirm on my stable test box that the following image has the updated changes needed for zsh and bash to work properly using the bling.sh file as expected.

Hi folks — just checking in to see if this is considered resolved now.
The recent refactors in the latest Bluefin images, it looks like the ZSH/BASH detection issues in bling.sh may already be fixed.
Can anyone confirm whether current images fully address the problem described here, or if further action is still needed?
Thanks!
