How to return back to the interactive shell directly from any function on the stack

[MidAutumnMoon]

My question is, in a scenario that a parent function called another child function, where that parent is called on the interactive shell, is it possible to return directly back to our interactive shell from that child function?

The current solution is to use return with and/or checks manually after each call to child, which is not elegant in my opinion. I want something like exit but without causing the fish process to shutdown.

The only thing approximating non-local control flow is signal handling. This "sort of" works:

function child
	echo "Child ran"
	kill -INT $fish_pid 
	echo "This will not run"
end

function parent
	echo "Parent ran"
	child
	echo "This will not run either"
end

parent

and will restore interactive control. It runs into problems if the child function is in a pipeline, etc. but maybe this is good enough for your use case.

Thanks! I will take this tricky method into consideration.

There's breakpoint - if this was for some kind of "something went wrong" situation - this is specifically for just getting a chance to change things before continuing to the control flow (or return early).
