Allow NewTab Action to specify the shell that will run

[giggio]

Additionally to the current options to the NewTab command (cwd etc), I'd like to have the option to specify the shell that will run.
Reason: I've been using Nushell for a while, but I still go back to Bash every now and then, and having a keyboard shortcut that allows me to quickly go there would be very helpful.

you can create a new layout that runs bash like this:
https://zellij.dev/documentation/creating-a-layout#command

both the CLI/keybind NewTab action take a layout.

related:
zellij actually support overriding config in layouts:
https://zellij.dev/documentation/layouts-with-config

so, you could set default_shell "nu" in the layout file, unfortunately this doesn't work with the new-tab action:

Note: These fields are ignored when loading a layout through the new-tab action

it does work if you create a new session and choose that layout, but I think setting a pane to run bash is easier for your use case.

I don't work a log with splits, I prefer to have my terminal fullscreen, so the layout solution wouldn't help me. I need a quick keyboard shortcut that opens a new tab on a different shell.

I'm not sure I understand what you mean about splits.

Here's an example with layouts, my default shell is zsh but I can pass this layout to new-tab to start with bash:

layout {
  pane size=1 borderless=true {
    plugin location="zj-status-bar"
  }
  pane command="bash"
}

zellij action new-tab --layout ~/.config/zellij/layouts/bash.kdl

oh nvm, new panes will still open your default shell, maybe that's what you meant.

rather than having new-tab take a new param it might be better if config overriding would be supported like mentioned above.
