What shell does scrollback_lines_to_serialize support?

[imsnif]

All shells are supported as long as they use the native terminal scrollback (afaik all shells do this).

I type nu to enter nushell. When I restore session, the pane only asks me to re-run the command nu. That's all. I lost all nushell scrollback history. So what should I do to restore nushell? Thanks a lot.

You should not "start nu" manually. It should be your default shell. Either true default (but I’m not sure they advertise for that for the same reason fish does not advertise for that) or by configuring nu as the default in zellij:

In "~/.config/zellij/config.kdl", set

// Choose the path to the default shell that zellij will use for opening new panes
// Default: $SHELL
//
default_shell "nu"

Thanks for the tip. I tried to set nushell as default_shell. The scrollback restore works randomly.

Edited:
I found the problem why it works randomly. Basically, the session and scrollback will require 60+ seconds to be saved. The doc says the zellij serializes the session data every 1 second and never mention it requires 60 seconds.

From my point of view, I think every change should be saved to disk instead of relying on any kind of time intervals.
