Great! I was waiting for this, to move some other things forward. This will be great building block! Have you tested it with Rye shell session in practice?

[rokostik]

@refaktor yes, tested everything I could in interactive shell sessions. I also want to write tests for this but haven't gotten around to doing it yet.

[refaktor]

Great! :)
Did you load it by opening the shell and doing do load %shell_... file or somehow else so I won't be mentally reinventing the wheel :)

[rokostik]

I did the simplest thing possible... savign the state and inputting it by hand from the saved file 😅 I looked at the shell code and I don't think it's currently possible to load the state from a file and continue from there right?

[refaktor]

:)
you can do do load %file in shell or if shell dump/script would have enter-console "" at the end it would enter it. I will probably add some flag to rye executable where it loads a file and enters console after it.
